Does Start Stop Wear Out your Starter? (Best solution)

The aim is to make it easier for the starter motor to do its job. “Using cheaper oils can cause more damage to your car’s engine than anything else,” he told Practical Motoring. “Operational stop-start causes no wear and tear at all; wear and tear at cold start-up is a thing, though,” he said.

  • Most people think a start stop starter wears out quickly. Well, eventually yes. But not as quickly as you think considering how many more cycles they go through on a daily basis. Traditional starters are designed for 50,000 starts.

What causes a starter to wear out?

CAUSES OF FAULTY STARTERS: CAUSE OF FAILURE Electrical connections faulty. Solenoid switch (engaging relay) stiff or faulty. Electric motor damaged electrically. Single-pinion gear, starter pinion or freewheel damaged.

Is Start Stop reliable?

Stop/Start systems aren’t as potentially damaging as cold starts, though, simply because the engine isn’t cold. Not only are the engines at operating temperature before the stop/start system begins to work, the vehicles also use electric water pumps to maintain optimal engine temperature when they’re stopped.

Why did my car starter stop working?

Cause: It is rare, but does happen – in most cases, this is caused by a dead battery in the vehicle or the battery having been disconnected when being serviced. Remote starters usually have some type of non-volatile memory to retain things like programming features and remote control codes.

What are the signs of a bad starter?

Symptoms of a Bad or Failing Starter

  • Engine won’t turn over. The most common indicator that a problem with your starter exists is when you turn your key and nothing happens.
  • Starter engages but doesn’t spin the motor.
  • Grinding noise when trying to start the motor.
  • Smell or see smoke when starting the motor.

How long does a stop/start battery last?

How long so start stop batteries last? While the majority of regular LSI batteries are generally guaranteed to last around four years, they can in fact go on to last up to six or seven years.

Why do cars shut off when stopped?

The concept of the stop-start system is simple. It automatically shuts off the engine when the vehicle is at rest to cut fuel use and eliminate idle emissions. It then restarts the engine automatically when the driver lifts off the brake (or puts in the clutch to select 1st gear) to get going again.

Is Start Stop bad for a turbo?

Manufacturers do guarantee that cars with stop-start fitted will suffer no reliability gripes for their foreseen active duties. It’s genuinely very bad for an engine (any engine) to be turned off with red-hot turbo(s) and this is an area where stop-start could really do some damage.

Why is my car not starting but the battery isn’t dead?

If your vehicle won’t start, it’s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you’re dealing with a battery or an alternator problem.

When your car won’t start but all the lights come on?

Similar to the starter engine, a broken or damaged ignition switch can stop your car from starting. If your headlights can turn on, but your car won’t crank, that means that your battery is charged, but either the starter or ignition is the problem.

Is it my battery or starter?

When the car won’t start, the most logical place to start is with the battery. You may require a jump to get the battery going again. If you are able to jump your car off and keep it running, but then dies again when you shut the car off, this is a sign there is an issue with the battery. Look over the battery itself.

Would a bad starter cause a car to stall?

While it is very unlikely for a running engine to die or stall due to the bad starter motor. However it still possible. It must be a series of events before that can happen. The bad shorted starter motor will cause a car battery to discharge.

Can a bad starter drain your battery?

A faulty or bad starter system can drain your car’s battery leaving it useless when in need. A good starter system draws only the amount of power it requires for initiating. Logically, a bad starter can drain a car battery by drawing too much power even when it is not in action.

Don’t start-stop systems wear out your car’s starter?

Start-stop systems are here to stay, despite the fact that some are hardly detectable and others cause the car to tremble each time they are activated. They were first implemented in Europe and Asia, where congested city driving necessitates automobiles spending more time at a stop. They automatically shut off the engine while the car is not moving. When the driver begins to raise their foot from the brake pedal, they swiftly restart the engine in order for the vehicle to move away from a stoplight or traffic congestion.

The majority of such systems already maintain the functionality of the vehicle’s accessories, including the lights, wipers, audio system, and climate control.

However, in stop-and-go traffic, this is typically sufficient to save a large amount of gasoline.

Start-stop systems took longer to make their way to the United States, in part because they didn’t give much of a benefit even in the Environmental Protection Agency’s city-driving test cycle.

  • However, the biggest concern that most automobile purchasers have concerning modern start-stop systems is whether or not they would cause damage to their vehicle’s starting motor.
  • The answer is a resounding nay.
  • This individual requested that we keep his identity a secret for a variety of reasons, one of which being that his present employer had not authorized his remarks.
  • ‘In these instances, automotive engineers do not employ ‘conventional’ starting motors,’ he stated.
  • (1) The gear ratio between the starter-drive pinion and the flywheel ring gear has been improved in order to make the starter’s motor rotate more slowly.
  • WE WILL EXPLAIN: How Can You Make Drivers’ Experiences with Start-Stop Systems More Pleasant?
  • The longer the life of a high-torque motor is extended by allowing it to spin more slowly throughout the coast-down process.
  • Starting-stop starters mostly rely on needle bearings for the rotating assemblies, rather than oil-impregnated bushings, which are more expensive.
  • A distinct design for turning power on and off to the motor is possible, maximizing contact design and wear, as opposed to contacts that have to be incorporated as part of a spring-loaded plunger assembly, as shown in Figure 1.
  • In addition, start-stop motors are combined with other technologies that determine when each cylinder of the engine will reach top-dead center, as previously mentioned.

The whole technical explanation of why you don’t have to be concerned about starting motors wearing out prematurely as a result of start-stop systems is now complete. GreenCarReports may be found on Facebook and Twitter.

Does Start Stop Wear Out your Starter

The majority of people
believe that a start-stop starter wears out soon. Yes, eventually, eventually. Considering how many more cycles they go through on a regular basis, this will not happen as rapidly as you may expect. Traditional starters are built to last for 50,000 starts or more. Stop start starters are intended to be used for 200,000 or more starts before failure. The reason behind this is as follows.

Start stop starters are gear reduction starters

Gear reduction is included into the design of start stop starters. Start stop starters with a gear reduction ensure that the motor continues to spin at the same speed, but the start motor turns at a considerably slower pace than a standard starter. What is the significance of this? The reason for this is because 90 percent of the carbon brush wear in a standard starting happens during the coast down period after the starter has been switched off Do you understand what I’m saying? The majority of the brush wear does not occur during the cranking process, but rather during the cleaning process.

Because the cranking and coasting speeds of a gear reduction starting are far lower than those of a typical starter, the coasting duration is significantly shorter, resulting in significantly less brush wear.

Start stop starters use a different brush composition

On springs, traditional starters make use of a carbon brush. Over time, the carbon brush wears a groove into the commutator of the motor, causing it to fail. The failure of the starter is caused by brush and commutator wear. A start-stop starter, on the other hand, makes use of a different mix of carbon and copper in order to achieve a longer life and to need less pressure against the commentator.

Start stop starters use different bearings

Traditional starters support the motor shafts using sintered bronze oil-impregnatedSintered Bronze Bearingsleeve ‘bearings,’ which are also known as ‘sleeve bearings.’ Sintered bearings do not rotate in the same way that a standard ball bearing does. As an alternative, sintered brass sleeves are formed from ground-up brass that is compacted under high pressure to form a tube-like structure. Keep an eye out for the pores in the sintered bronze ball bearing. That’s where the oil has taken up residence.

In order to provide lubrication, oil is physically drawn into the spaces between the ground up brass particles, and this oil is what keeps the machine running.

As a result, needle bearings are used instead of ball bearings by start stop starter manufacturers.

Start stop starters use different solenoids

In a typical starter, the solenoid performs two functions: it brings the pinion gear into proper alignment with the flywheel teeth while simultaneously functioning as a power switch, allowing battery power to be sent to the starter motor through the starter motor. The start stop solenoid has only one function: to bring the pinion gear into proper alignment with the flywheel. A different method is used to switch on and off the electricity. An electrical starting with this feature prevents the arcing and pitting that occurs on electrical contacts in a standard starter.

Because the solenoid in a start stop starting does not have to keep the contacts against one another during cranking, the solenoid in a start stop starter requires significantly less power to function, which in turn decreases the total current required for cranking by a significant amount.

Start stop starters integrate with piston position

Rather than waiting for the crankshaft to turn completely around, a start-stop system fires the fuel injectors in the middle of a complete rotation rather than at the end of the rotation. Consequently, a piston can reach top dead center faster, and the IGN system can fire earlier, resulting in shorter crank times and energy consumption.

There are many start stop starter designs

The term ‘start stop starters’ refers to starters that are essentially beefed up versions of the regular starter. In addition, they include dual layer brushes and an entirely new pinion gear spring system that decreases the wear on the ring gear and flywheel by about ninety percent.

Tandem solenoid start stop starter

Whereas a standard starter can only engage with the flywheel when the flywheel is spinning at zero rotation, a tandem solenoid design can interact with the flywheel at any rotational speed up to and including 600 rotations per minute. This reduces the amount of time it takes to restart.

Permanently engaged starter

The flywheel spin of a standard starter is limited to zero rotation, but a tandem solenoid design may interact with the flywheel at any rotational speed up to and including 600 rotations per minute. Thus, the time required for restarting is reduced significantly.

Auto-Start/Stop: Is It Bad For My Engine? (Mythbusting)

By the end of 2012, the Obama Administration had finalized the rules for automobile manufacturers, with the goal of achieving a corporate average fuel efficiency of 54.5 miles per gallon by 2025. Manufacturers used a range of updated technology, such as Auto-Start/Stop, to aid in the achievement of this aim. A rising number of people, however, are concerned about whether or not the Auto-Start/Stop system wears out engine components. In this unbiased investigation, we look at how the Auto-Start/Stop system works and if it might cause damage to your engine.

There is no evidence that automated start/stop causes the starting motor or other engine components to wear out more quickly than normal.

Some engines also start nearly solely using compression, which is a rare occurrence.

What is Auto-Start/Stop Technology?

When the vehicle comes to a complete stop at a traffic signal or stop sign, the Auto-Stop/Start feature will briefly turn off the engine. When you are ready to get back on your feet, the system will automatically begin working again. Unless you spend the vast majority of your journey on the highway, it is unlikely that you will notice the fuel-saving advantages of this technology. However, urban commuters who are stuck in stop-and-go traffic will see a significant improvement in their car’s fuel economy as a result of the adjustment, with up to five percent greater efficiency being achieved.

How Does Auto-Stop/Start Work?

Automatic stop/start systems are available from a variety of manufacturers, with Denso serving as the major provider. It is this business that offers Auto-Stop/Start technology to all of the American automakers, including Audi and Volvo, as well as Fiat, Toyota, and Hyundai. When the car comes to a complete stop, this sophisticated technology recognizes it. It knows to activate because sensors have detected that the brake pedal has been pushed and that the engine RPM has lowered. The engine is turned off, and the transmission is disengaged by the system.

While the technique makes use of the starter to turn the engine, there are a number of other components that are involved in the overall process.

Because even if the engine has temporarily stopped, the vehicle’s accessories continue to operate as usual throughout this period. It is unlikely that you will notice any differences in the air conditioner, windshield wipers, or radio throughout this procedure.

Is Auto-Start/Stop Bad for the Engine or Starter?

Starting your automobile is the most damaging thing you can do to its engine. But it is the cold-starting of the engine that does the most damage to the engine’s components. Putting a cold cup into a pot of hot water is similar to starting an engine after hours or days of inactivity, except that the damage does not occur as quickly. Using the Auto-Start/Stop feature, the car’s engine is not cold when it is started. Despite the fact that the engine was running only a few seconds ago, it will restart while the motor is still warming up.

  1. For as long as the key is still in the ignition, the technology will begin to operate the vehicle before it enters the danger zone.
  2. In order to incorporate the new technology, other sections have also been modified to reflect this.
  3. Providers are constantly looking for ways to improve upon the Auto-Start/Stop system, developing better procedures and more energy-efficient machinery.
  4. Instead, it makes use of engine combustion to propel the vehicle forward.
  5. In spite of this, you will find plenty of folks on the internet who will warn you how destructive Auto-Start/Stop is to your engine.
  6. Unless and until compelling proof to the contrary is presented, it is reasonable to presume that current automobiles are built to withstand the impacts of Auto-Start/Stop technology.

How to Disable Auto-Start/Stop Technology?

The Auto-Start/Stop system in your car can be overridden manually if your vehicle is equipped with this feature. In many circumstances, all that is required is the push of a button to turn off the technological system. It’s important to remember that if you switch off the Auto-Start/Stop feature, your car’s fuel efficiency may suffer by as much as five percent. Additionally, because the manufacturers have not developed a mechanism to permanently override the system, you will have to manually turn it off every time you start the car to avoid being charged.

In this instance, you are probably not overly concerned with fuel efficiency and are instead searching for the highest potential performance from your vehicle.

It is preferable to leave the Auto-Start/Stop function turned on whenever feasible, not only to save money at the gas pump, but also to limit emissions into the atmosphere. Isn’t it true that we all want to do our part to rescue our planet?

Does Auto-Stop/Start Technology Wear Out Engine Components?

Even if your automotive mechanical knowledge is limited to prime-time television advertising, you are surely aware that the majority of engine wear occurs when you first start your car and that this wear is the most costly. Has our society progressed to the point where most new automobiles are equipped with auto-stop/start technology, which increases the number of starts in an ordinary commute by 100 times, making us more vulnerable to engine and component failures than we were previously? When Do We Need Auto-Stop/Start Technology, and What Is the Benefit of Using It?

It doesn’t take a rocket scientist to figure out that you save a lot of fuel when the car isn’t running at all.Find a Hybrid with Auto-Stop/Start Technology at BestRide.comAuto-Stop/Start technology automatically shuts off the engine when the vehicle comes to a complete stop and then restarts it when the driver wants to get back on the road.Find a Hybrid with Auto-Stop/Start Technology at BestRide.

The Auto-Stop/Start feature won’t save you much money if your commute consists of a single stoplight and a long stretch of highway; however, if your commute is anything like the majority of Americans’, with a lot of stop-and-go traffic on your way to and from the office, it can save you anywhere from three to five percent on your fuel consumption.How Does It Work?

Generally speaking, auto-stop/start detects that the vehicle has come to a complete stop and that the engine RPM has dropped to a full stop or close to it, as well as that the brake pedal has been depressed.At that point, the system shuts off the engine and disconnects the transmission.

When the system detects that the driver is lifting her foot off the brake, it automatically restarts the engine while the transmission is still in gear.

The pinion gear, which you can see in the animation below, must also be moved out of the way so that it does not become engaged with the ring gear on the flywheel once the engine is running.For a vehicle that only needs to be started a few times a day, it’s an ingenious little device that has remained virtually unchanged since Charles Kettering received a patent for it in 1917.via GIPHYHowever, vehicles with auto-stop/start systems must be started dozens, and A typical starting, like as the one made by Boss Kettering, will simply not do the job.Find a Vehicle Equipped with Auto-Stop/Start Technology at BestRide.comDenso offers three distinct types of Auto-Stop Start starters, depending on the application and the manufacturer’s requirements:

  • With dual-layer, long-life electrical brushes and a unique pinion spring mechanism that reduces ring gear and flywheel wear caused by typical starters by approximately 90 percent, the first starter is fairly traditional in design
  • However, it has been engineered to be more durable than its predecessor. The second type of starting is a ‘Tandem Solenoid’ starter, which allows the engine to re-engage with the starter motor at any speed between idle (about 600 RPM) and zero RPM, depending on the engine speed. A standard starting would take two seconds and a half to restart the vehicle
  • The most sophisticated Denso starter, developed in collaboration with Toyota, would take only a single second and a half to restart. When it comes to starting the car, it is referred to as a ‘Permanently Engaged’ starter because, as the name implies, the pinion gear is permanently meshing with the ring gear on the flywheel, which prevents any lag time when the vehicle has to be restarted.

Try out a few different automobiles when you’re out shopping for your next car to see how each one handles the auto-stop/start system in different ways. It can be done more or less flawlessly by certain individuals. Others, as Ray Magliozzi described it in his column this week, ‘start with a minor earthquake of a tremble’ to get things going. As an additional measure, starter makers employ rubber shock absorbers and clutches to isolate engine oscillations, which helps to decrease engine-restart noise and engine-stop vibrations.

  1. What Is the Status of the Transmission?
  2. In reality, before 2007, the only automobiles equipped with auto-stop/start technology were those equipped with a manually-shifted transmission.
  3. When you’re stuck in traffic, you don’t have the option of moving the car into park every time you come to a complete stop.
  4. When the car comes to a complete stop, they automatically shift into neutral.
  5. When the driver presses the accelerator, it comes back into play.
  6. It is widely understood that the cold start of an engine is the most susceptible period for internal engine components.
  7. Stop/Start systems, on the other hand, are not as potentially destructive as cold starts, simply because the engine is not cold when the system is activated.

If the engine is turned off for a period of time sufficient to drastically lower engine temperature, the engine will automatically restart.

Finally, providers are addressing wear on components such as primary engine bearings by using dry lubricants on them.

New bearings are currently in use, and they are designed to survive 250,000 to 300,000 start cycles, depending on the application.

What if I don’t like it?

To our knowledge, there is no manufacturer that permits you to permanently stop the function.

The future of any of this technology is still uncertain, and manufacturers and suppliers are attempting to create other means of achieving the same aims without having to overcome the technological obstacles.

It is powered by engine combustion.

In the near term, though, you shouldn’t be concerned about whether or not your engine or its different components are being harmed as a result of repeated starts.

They’ve been designed specifically for it, and they’re designed differently from the components in a car that doesn’t have this technology.

Is Your Car’s Start-Stop System Hurting You in the Long Run?

There are a variety of tips and techniques available to assist you in increasing your fuel efficiency. And one of them is rapidly being integrated directly into automobiles. Many modern automobiles are equipped with a start-stop technology, which is intended to decrease the amount of petrol used when the vehicle is idling. But, in reality, does this function actually save you fuel? And even if it does, are there any long-term ramifications that may arise as a result of this?

How does the start-stop system in your car work?

Close-up of the start-stop system deactivation button on the Mercedes-AMG GLB 35 in 2021 | Matthew Skwarczek is a writer and musician from Poland. Start-stop systems, also known as ‘auto start-stop systems,’ were first developed in the 1970s but have only recently gained in popularity due to their ease of use. The advancements in automobile electronics, particularly in starter motors and hybrid powertrains, are to credit for this development. Despite the fact that each start-stop system is slightly different, they all function in a similar manner.

  • The ECU then momentarily disables your vehicle’s fuelling and ignition systems, thereby turning off the engine.
  • It’s even feasible to equip cars with manual transmissions with start-stop systems,CJ Pony Partsnotes, if the vehicle is equipped with one.
  • However, manufacturers have taken a number of initiatives to address this issue.
  • Hybrid vehicles can also ‘smooth out’ any residual coarseness due to the fact that their starter motorsoften doubles as a generator.

Does using the start-stop system damage the engine or other parts of your car?

However, no matter how advanced stop-start systems are, they are not foolproof. And, more importantly, employing them means that your car’s engine will switch on and off many times during a single journey. As a result, some consumers have expressed worry that the technology may be speeding up engine wear and perhaps inflicting long-term harm.

  • Aside from that, starting motors, as well as the batteries that power them, do ultimately wear out.
  • RELATED: Maintaining Your Car or Motorcycle Battery to Prevent It From Going Flat However, according to RAC, these potential problems have been rectified in the majority of instances.
  • Furthermore, many stop-start systems do not activate until the engine has reached operating temperature.
  • Second, vehicles equipped with start-stop systems, whether hybrid or not, have starters that are overbuilt and large in order to solve wear-and-tear problems.
  • If this occurs, the engine continues to operate in order to replenish the battery.

According to Haynes, the stop-start mechanism is also aware of whether or not your air conditioning is functioning. If this is the case, the engine continues to operate in order to keep it operating. In addition, if your heater is on, the situation is the same, CJ Pony Parts explains.

However, while start-stop systems are unlikely to cause damage to your engine, are they actually beneficial in terms of fuel economy? Yes, in a nutshell. However, like with any fuel-saving technology, the amount of money you save is dependent on how and where you drive. As previously stated, if your HVAC system is functioning, your engine will not shut down automatically.

When Edmunds evaluated the start-stop system on a Mini Cooper, the reviewers discovered that using the air conditioning resulted in a 2.9 percent boost in fuel efficiency.

In addition, the Jaguar and BMW that were tested alongside the Mini both reduced their fuel consumption by around 10% by utilizing start-stop technology.

So, unless you absolutely despise the frequent restarts, it’s worthwhile to keep it running.

Stop-start systems: is there a long-term impact on my car’s engine?

More information may be found at: How to Buy a Used Car – Expert Tips When the driver has made the decision to stop, but for any reason changes his or her mind, such as when the traffic pulls away abruptly, this is an example of what happens. Because the engine may be ‘committed’ to stopping yet is still spinning at that point, one solenoid cranks up the starting motor to bring it up to speed with the engine before the second solenoid smoothly engages the gear. This prevents crushing.

Disadvantages of stop-start technology:

When it comes to durability and long life, all of the bases should be covered when it comes to the starting gear itself. However, the increased frequency of stop-start cycles leads to greater engine wear unless measures are taken to avoid it in the first place. Gerhard Arnold, Federal Mogul’s bearing design manager, estimates that a typical automobile, without automated stop-start, will experience up to 50,000 stop-start occurrences during the course of its lifetime.’ ‘However, because the automated stop-start feature is engaged every time the automobile comes to a complete stop, the amount increases substantially, possibly reaching as many as 500,000 stop-start cycles throughout the engine’s lifetime.’ That is a significant increase in distance traveled, and it presents significant problems to the durability and life of the engine’s bearings.

The crankshaft is a critical component of the engine, as well as one of its most substantial and heavy components.

These are the major bearings, and the effect is most noticeable on the bearing at the back of the engine, directly near to the starting motor, which is the most damaged.

However, as the engine comes to a halt, the crank settles into the bearing, resulting in the two metal surfaces coming into contact. This is referred to as ‘hydrodynamic lubrication.’ More information may be found at: Winter automobile maintenance advice.

How rust helps to prevent wear

When the engine is first started, there is a period of time before the two bearing surfaces get divided by the oil film known as the ‘border condition,’ during which the crankshaft is rotating but there is metal-to-metal contact between the bearing surfaces. This is the time of year when the most wear occurs. Because of the stop-start feature, the boundary condition (and metal-to-metal contact) might occur possibly 500,000 times throughout the engine’s lifetime instead of 50,000, resulting in typical bearings wearing out far sooner than 50,000 times.

The first is that bearing manufacturers are researching and developing novel bearing materials with improved self-lubricating qualities in order to prevent wear during initial startup operations.

Irox is coated with particles of iron oxide (rust), which in this microscopic form is astonishingly slippery.

Low friction oils help prolong engine life

The second point to mention is advancements in lubricating lubricants. Modern engine oils have an additive package that is comprised of a complicated chemical cocktail that is designed to enhance performance. Martyn Mann, technical director of the Millers Oils firm in the United Kingdom, believes that the composition of these packages is critical: ‘We’ve decreased friction with our oils and increased the longevity of the oil layer, and we believe that this is the way to go in the future with stop-start systems,’ says the team.

According to Mann, ‘we developed a formulation and tested it on a friction rig, and discovered that we could reduce the sliding friction between conventional components such as pistons and liners by 50%.’ More information may be found at: What type of oil should I use in my automobile?

The engine surfaces are adhered to by tiny nano-particles such as miniscule ball bearings that exfoliate under high pressure, leaving behind polymer ‘flakes.’ Currently, the technology is only available in Miller’s high-end racing lubricants, but in the context of stop-start racing, it has the potential to minimize wear at each re-start, which is when the most wear occurs.

While current technology is still in its early stages, only time will tell whether or not every automobile manufacturer has gotten it quite right.

Does stop-start help save fuel?

Idling the engine when stationary in conditions such as heavy traffic or waiting for traffic lights to change can conserve the amount of gasoline that would have been consumed by the engine if you had driven away from the stoplight instead. The amount of gasoline saved is sometimes debated, and it is nearly completely dependent on the sort of driving conducted when using the system. Obviously, the more time spent motionless, the more gasoline is saved. It is possible that stop-start will not activate in some circumstances.

Similarly to Volvo’s system, it may fail to shut off the engine when the battery voltage falls below a specific threshold, when the driver unfastens their seatbelt, or when the air conditioning is turned on.

Does start/stop damage starter?

However, the most often asked topic about newstart-stopsystems is whether or not they would wear down the car’s startermotor over time. The answer is a resounding nay. (1) The gear ratio between the starting -drive pinion and the flywheel ring gear is tuned in order to make the starter’s motor turn more slowly than it otherwise would. Installation of the incorrect battery technology, which can only support a limited number of charging cycles, has occurred. The outdoor temperature is either too hot or excessively low.

  • The temperature of the engine is either too high or too low.
  • A.Stop-start technology is becoming increasingly popular since it is typically reliable and helps to reduce fuel usage and pollutants.
  • What might cause damage to a starting motor is another question that may arise.
  • The solenoid switch (also known as the engaging relay) is stiff or defective.
  • What is the best way to start a car with a faulty starter?
  1. Check the connections to make sure they are secure. The first item to examine is the connections
  2. This is essential. Check the engine’s grounding system. In contrast to a battery, a starter does not have a ground wire that connects to it. Check the wire that connects to the starting solenoid. Check for corrosive materials. Using a hammer to tap on the starter’s starter
  3. Start the automobile using a jump start
  4. Bypassing the starting relay is possible. Start the automobile by pressing the start button.

Auto engine shutdown systems such as Mazda’s i-Stop are said to as the ‘Coca-Cola’ of automotive technology, and while the company attempts to spice up its benefits, the automobiles would be better off without it. The vehicle engine shutdown and restart system is one of the most egregious examples of this self-serving design goal on the part of the automaker. You continue driving. You come to a complete halt at a red light. After a while, the engine will shut down on its own. When the light turns green, you begin to raise your foot off the brake, and the engine begins to rev as if by magic, revving again.

Systems such as Mazda’s i-Stop – as well as what seems like an infinite number of other proprietary names for comparable bogus technology –


I receive inquiries regarding this on a regular basis; one such inquiry came to me lately in the normal manner (by carrier pigeon): ‘When I was an apprentice 30 years ago, we were told that the process of starting an engine accounted for around 80% of the entire wear and strain on that engine. In addition, idling the engine for 10 minutes burned almost the same amount of gasoline as starting the vehicle. In light of the fact that these facts are still valid, how can the stop/start option be considered beneficial?

TI Apart from that, I am frequently contacted by people who have concerns regarding early wear and tear on the starting system.


First and foremost, automatic engine shutdown and restart systems save you a ton of money on gasoline. Claims made by automobile manufacturers that you would save a significant amount of money are complete and utter bunk. Even if you leave your engine running all day, it will still not cost you as much as a burger and fries at a fast food restaurant. At idle, engines simply do not burn much gasoline since they are just driving the ancillaries and overcoming their own internal friction, as well as a little amount of drag in the torque converter (if the engine is driving an automatic gearbox) and overcoming their own internal friction.


However, the underlying reason why these automatic technologies are used in many new automobiles is so that the automaker may legally ‘game’ the government-mandated fuel economy testing. We’ve talked about these examinations in the past. They are laboratory tests from which the official fuel consumption estimates are obtained – and these values are extremely significant to vehicle manufacturers since fuel consumption is becoming increasingly relevant to regulators and purchasers. The tests are, however, not very reflective of real-world driving situations.

  1. Unfortunately.
  2. Those valleys over there, aren’t they?
  3. When taken together, the two exams take 20 minutes, with approximately one-third of that time spent halted.
  4. Consequently, if you’re a vehicle manufacturer, and you’re in this fierce rivalry with all other car manufacturers, and you add the engine shutdown option in the car, over half of the official city cycle test is spent with the engine turned off.

You’ll get a little advantage over a competition who doesn’t have such equipment in his vehicle. Consequently, you have successfully gamed the system, and nothing unlawful has occurred as a result.


However, what this implies for you as the automobile owner is that you are required to wear it. And it’s nasty – especially when the computer is restarted. This is especially true with a diesel engine, which must contend with a tremendous amount of compression as it restarts. And this is especially true if your vehicle is equipped with a continuously variable gearbox (CVT). They have a reputation for having quite aggressive torque converters. As a result, the restart is rudimentary at best. It’s a nightmare.

  • It’s fantastic.
  • Everything is fine.
  • However, the re-start has the feeling that crack-smoking zombies are assaulting from below the hood.
  • German automobile manufacturers have received some bad news: When the automobile feels like it’s on active service and taking fire in Fallujah, it’s not exactly a luxurious experience.
  • Instead, the default state on every starting is ‘active’, which makes them difficult to turn off completely.

For added aggravation, certain automakers – I’m looking at you, Subaru and Mazda – don’t allow you to entirely switch off the system, or at the very least not as thoroughly as you’d want. While you may press and hold the button to temporarily disable it, the default status on restart is ‘active’ every time you come back in the car for another go at driving. And if there is a method to stop it permanently, you’ll either need to be a computer programmer or a 15-year-old to figure it out, which seems unlikely.

  • When you stop to think about it, that is the pinnacle of Japanese technical hubris right there in one sentence.
  • For example, if you want the radio off and so you turn it off, every time you go back into your car, the radio is turned back on with the volume set to ‘9’ once again.
  • I suppose they are the most knowledgeable.
  • Whatsoever.


However, there are also additional aspects to consider, such as wear and tear. First and foremost, let’s talk about the beginning system itself: Almost everything may be designed to be dependable for an unlimited number of cycles. For example, if the system is shutting down and restarting (I dunno) 50 times a day, six days a week, that’s 300 cycles in one week. That equates to 15,000 cycles every year, or 300,000 cycles throughout the course of the vehicle’s 20-year service life.

I don’t see it as being a particularly difficult struggle for a half-competent research and development staff. As a result, the durability of the starter and solenoid – and so on – and all of the gear – is not a concern.


Wear and tear, as well as fuel consumption, are addressed in John’s carrier pigeon points. To be honest, the amount of wear and tear on an engine is always at its highest when the engine is started from a cold state. Isn’t it true that the clearances are incorrect because the metal pieces have not expanded to their normal working temperatures? Additionally, a significant amount of oil has managed to drain away from the bearings and other critical parts over a period of several hours while you were doing whatever else you were doing, and it takes a few revolutions of the crank to pressurize all of the oil galleries, and of course, if you never allow the engine to warm up, you also get a significant amount of water contamination in the sump, which does not help either, and it is not recommended.

In this case, wear and tear is less a result of the initial cold start-up than it is a function of the extremely early beginning cold operation.


With a hot start, none of these issues are really a concern. Assuming the engine is fully operational, there is sufficient of oil ‘upstairs,’ and all of the components are in good working order, the wear rate is nearly nil. And these systems are rather sophisticated; some of them even manage to coordinate the engine’s halt at precisely the proper location for a restart. Essentially, this implies that one of the cylinders’ compression stroke should come to a stop around the top dead center of the stroke.

An engine that is up to date does not require any more gasoline when it starts on the first try.

(These are beautiful gadgets, but they are quite wasteful and also rather unstable.)


The other issue raised by John regarding significant fuel use at starting is supported by two key facts. For starters, and this is still true today, a rich fuel/air combination is required for a cold start. Automatic choke removal in fuel-injected engines is analogous to taking the manual choke lever out of an old car’s engine. Do you remember when you did that? However, this does not apply while resuming in traffic. First and foremost, when John was taught this information as an apprentice in the 1980s, automobiles still had carburetors: remember those?

  1. One of those issues was that as you opened the throttle, the manifold vacuum dropped, which was problematic since you were also utilizing that vacuum to feed fuel to the carburettor at the same time.
  2. So that’s a negative sign.
  3. It’s as though the engine stutters for a moment before deciding to begin moving again.
  4. Its purpose is to squirt in a small amount of more fuel in order to fix the stutter.
  5. Consequently, if you’re my age – that is, older than Facebook plus 30 years – you’ll recall the intricate routine dad had to go through in order to start the family car.
  6. You know the drill: choke at three-quarters throttle (not eleven sixteenths or seven eighths), two pumps on the gas, count ‘one potato, two potato,’ pray, start – and hopefully that’ll be the last of it!

And it goes through all of this nonsense on its own. Thankfully. Many stop-start systems employ capacitors and other electric storage devices to resume in the event of a battery failure. Car batteries are designed to withstand shallow cycling (many restarts) quite well.


Finally, and without wishing to be insensitive, the battery doesn’t seem to give a damn about the fact that the car has been started several times. (Some systems don’t even use the car’s battery, instead relying on a capacitor to store enough charge to restart the engine when the car comes to a stop at a red light.) Automobile batteries are completely tolerable to short restart cycles such as: start, charge, start, charge, start charge, repeat. That’s something they really like. For a long period of time.

Someone in the aftermarket sector should be really, extremely pleased with this development.


So there you have it: auto-stopping and restarting technology in action. Technology that is both clever and durable, but also perversely arrogant and full of nonsense at the same time. In addition to being inapplicable to you on a practical level. Let’s not lose sight of it. There you have it, a wonderful metaphor for many of the folks I’ve encountered in the automobile sector all in one location. And, of course, complexity is the nemesis of trustworthiness. It is unpolished because it is not providing you with any actual advantage, and it is thus simply another thing that might go badly wrong down the road, if you continue to consume this garbage.

  • So, if you’re test driving a vehicle that has automatic stop/start, take advantage of the opportunity to determine whether you can tolerate the restart in particular.
  • And don’t just take the salesman’s word for it; put it through its paces until you are completely happy.
  • I hope this has been of assistance.

Top 8 Reasons Why Aftermarket Fuel Savers Don’t Work

John Cadogan is a well-known actor.

What is automatic start-stop and how does it work?

In its most basic form, the start-stop system reduces fuel consumption and pollutants by allowing the engine to idle for brief periods of time, such as when waiting at traffic lights. As a result, the automated start-stop technology helps to conserve gasoline while also protecting the environment. With this method, CO2 emissions can be decreased by 3 – 8%, depending on the application. Automated start-up systems have been rapidly adopted across all vehicle classes as a result of the environmental advantages and increased economy that they provide.

How automatic start-stop systems work

The start-stop system identifies when the vehicle is at rest and, using sensors, it determines a variety of other aspects regarding the vehicle’s operating mode and behavior. When a motorist comes to a complete stop at a traffic signal and shifts the transmission to neutral, the start-stop system shuts down the engine automatically. Some more modern models even turn off the engine if the vehicle’s speed falls below a particular threshold. Despite the fact that the engine, and therefore the major source of power for all systems, has been turned off, all electrical consumers and aides continue to get electricity.

Immediately after engaging the clutch, the automatic start-stop mechanism kicks in and restarts the engine.

Even if the car is brought to a complete stop with the brake pedal still down, the engine will be shut down automatically by the automatic start-stop system. As soon as the brake pedal is depressed, the automated mechanism kicks in and starts the engine.

Sensors control the automatic start-stop system

The information regarding the driving situation that an automated start-stop system receives comes from a variety of sensors. In order to determine whether the vehicle is moving or not, sensors such as the neutral gear sensor, wheel speed sensor, and crankshaft sensor are used. The engine controller is in charge of coordinating the start-stop procedures and ensuring that they are in sync with the engine management system. The electronic battery sensor (EBS) transmits information about the status of charge, voltage, and temperature of the battery to a host computer.

When components of a start-up unit that are subjected to a high level of stress are strengthened and built for a long service life, the starter is better able to handle the pressures that come with an increased number of starts and avoid early wear and tear.

Recuperation and automatic start-stop systems New battery generations for innovative technologies

Instead of being limited even in cars equipped with automated start-stop systems, batteries with AGM technology were specifically built for vehicles that not only have start-stop technology but also an energy recovery (recuperation) system and other fuel-saving technologies. It is possible for a battery using AGM technology to accept the energy that it gets through recuperation with a high degree of efficiency. Batteries using EFB technology, on the other hand, are only intended for use in vehicles with entry-level automated start-stop systems.

Recuperation – how electricity is generated from braking energy

The generation of electrical energy occurs as soon as the vehicle brakes and the engine shifts into thrust mode, which is referred to as recuperation or recovery of braking energy. In automobiles equipped with recuperation, the generator recharges the battery with the recovered energy, which is then used to power the comfort features during the ensuing stop period. By combining this efficient technology with a strong AGM battery, it is possible to achieve higher fuel savings while also reducing emissions to a larger extent than with basic start-stop systems.

As a result, the whole motor power is available for acceleration, and the engine may operate at peak efficiency.
