What exactly is engine start stop technology?

The engine start-stop is to automatically turn off the engine when the vehicle is temporarily stopped while driving (such as waiting for a red light).

When it's time to move on, the system automatically restarts the engine. The engine start-stop system is the most rapidly developing automotive environmental protection technology in recent years, especially suitable for stop-and-go urban road conditions.

The start-stop technology increases fuel consumption. Automatic start-stop technology is mainly used in traffic jams, in which most of the engine is hot, and the fuel consumption of the hot car itself is not much.

At start-up and hot start, the speed and time have no adverse effect on the lubrication of the friction parts. Traditionally, it is believed that the wear and tear on the engine is in the state of cold start and high temperature cold start, with the current oil quality, as long as the oil can be used, then the impact on wear should be lower than the impact of high temperature.

The start-stop system works when the vehicle stops due to congestion or intersections. The driver presses the brake pedal and stops to disengage. At this time, the start stop system automatically detects:

The engine is idling and there is no gear; The wheel speed sensor of the anti-lock system shows zero; The electronic battery sensor shows that there is enough energy for the next start. When these three conditions are met, the engine automatically stops turning.

The automatic start-stop system works as follows:

When the condition of the whole vehicle meets all other judgment conditions of engine shutdown, ECM will control the engine to turn off; When the signal light or road conditions allow for continued driving, the ECM again determines the driver's intention to start by the driver's action (pressing the clutch), and thus controls the starter to start the engine, quickly returning the engine to normal operation.

For vehicles equipped with automatic transmissions, when the vehicle needs to stop and wait, press the brake pedal until it stops, the engine will be controlled by EMC to turn off, and the gear can also be shifted to P gear and the brake pedal can be released, and the engine will not start; When you need to continue driving, release the brake pedal and the engine starts immediately, and if you have previously shifted to P, the engine starts immediately when D gear is engaged.

What is the use of engine start-stop technology.

The shortcomings of automatic start-stop are obvious, the original design purpose of automatic start-stop technology is to save fuel, after the automatic start-stop function is turned on, the vehicle is in a "dormant" state in the process of short-term stopping, the pulley stops rotating, and at the same time tries to reduce the process of engine idling and idling.

After the engine is turned off, the engine pulley is replaced by the on-board power supply to keep the on-board fan running.

According to the estimation of professional institutions, the fuel saving rate of vehicles with automatic start-stop function can reach more than one-tenth in the actual use process, and the CO2 emissions that people are now paying great attention to will also be reduced a lot.

Now many cars are installed with the automatic start and stop function, but not many people use it, or use it for a period of time and no longer use it, thinking that the automatic start and stop function is too hurtful to the battery, and affects the driving experience, but in fact, the benefits of the automatic start and stop function are still many.

1. The main benefit of the automatic start-stop function is fuel saving.

When our vehicle starts again after a short period of stopping, because the engine is in normal operating temperature, the starting resistance is small, and when starting, the engine flywheel is started with the help of the starter, and the fuel consumption of starting at this time is only equivalent to the fuel consumption of idle seconds, so theoretically stopping for more than 1 second will have a fuel-saving effect, in addition, the German Bosch company has done relevant tests on the engine start-stop technology, and the conclusion is that the average fuel-saving rate of the engine start-stop technology is about 9%-14%, The more congested the road section, the larger the car displacement, the more obvious the fuel-saving effect, we have a similar test in China Automotive Technology and Research Center before, and the result is that the fuel saving rate is as high as 8%-27%, which is already a considerable part of the cost, and over time, you can save a lot of money, originally, the original purpose of the invention of this technology is to save fuel.

2. Reduce the generation of carbon deposits.

If the car engine is in such idling and low-speed operation for a long time, there is no great harm, but due to the low idle speed, the combustible mixed gas of the engine will not be fully burned, and it is easy to produce the accumulation and precipitation of carbon deposits in the engine, which indirectly affects the performance of the engine, shortens the life of the engine, and affects the normal operation of the engine. The automatic start and stop of the car can greatly shorten the idle time of the engine, thereby reducing the carbon deposit generated by the engine.

3. Reduce exhaust emissions.

Energy saving and emission reduction, because the automatic start-stop technology of the engine can allow us to pass through congested road sections or wait for red lights, the vehicle does not emit exhaust, thereby reducing the exhaust emissions of the vehicle. A few seconds less for one person, there are so many cars in the country, everyone is a few seconds less, our air quality will definitely improve several grades, and the beautification of the living environment starts from ourselves.

There are pros and cons to automatic start-stop technology, but any successful technology is to serve us, there is no perfect technology and flawless things in the world, so we enjoy the convenience of technology at the same time, but also to bear the corresponding burden, so as to balance, in addition, I wish the majority of riders smooth sailing, everything goes well!

Well, it's useful, and that's why in recent years, cars have engine start-stop technology, in order to save energy. For example, when you wait for a red light, it will extinguish the fire when you step on the brakes, and it will start when you let go, and you can go with refueling, which is more convenient. It's also more intelligent.

If there is no impact, don't worry.

1. The original intention of the engine start-stop technology is to improve fuel economy.

2. Generally speaking, the engine start-stop technique with concealment can indeed improve fuel economy to a certain extent. Because the engine is in a state of long-term low-speed operation when waiting for the red light, it not only wastes fuel but also easily leads to carbon deposition, which affects the service life of the engine. Therefore, during the 1 minute of waiting for the red light, allowing the engine to rest temporarily is equivalent to saving fuel and protecting the engine.

3. But these are the so-called ideal states, each country's road shelter is different, each owner's driving habits are different, in a special driving state, the engine start-stop technology may increase fuel consumption, and even threaten driving safety!

It refers to the automatic shutdown of the car when it stops temporarily during driving (such as waiting for a red light). One of the systems automatically restarts the engine when moving forward. The engine start-stop system is the fastest growing automotive environmental protection technology in recent years, especially in the stop-and-go urban road conditions that meet the objective requirements.

The driver was sitting in the cabin, and the red light at the intersection in front of him was on. The driver presses the brake pedal and stops to engage gear. At this time, the start-stop system automatically checks:

The engine is running empty, without gear; The wheel speed sensor of the anti-lock braking system shows zero; The electronic battery sensor shows that there is enough energy for the next start. Once these three conditions are met, the engine will automatically stop running.

When the signal light turns green, the driver can press the clutch to start the "start-stop" and the engine starts quickly. When the driver puts gear on the accelerator, the car starts quickly. Supported by high-efficiency battery technology and the corresponding engine management program, the start-stop system can function normally at low temperatures and can be activated with only a short warm-up process.

For different models of different brands, the design of the automatic start-stop system is not necessarily the same. The start-stop logic of a little car mode is not very good, the intervention time is not accurate, sometimes the start-stop system that stops for a long time does not respond, but when the card is swiped at the toll booth, a slight brake makes it uninvited. In addition, the noise and vibration at the start are relatively high, which is one of the most criticized shortcomings of passengers.

In addition, if the traffic jam is severe, the engine stops working for a long time, the combustion chamber temperature drops, and the unburned hydrocarbons and paraffin wax develop and change into carbon deposits attached to the inner wall of the cylinder. The situation is even worse if oil is scarce. Carbon deposits increase fuel consumption and weaken power.

This is an automatic start-stop function that is designed to reduce fuel consumption, but it increases fuel consumption. There is no doubt that automatic start-stop saves fuel. Under normal circumstances, the fuel saving rate of automatic start and stop can reach 5%-15%.

The larger the displacement, the more congested the road and the more obvious the fuel-saving effect. However, many people are concerned that the automatic start-stop will damage the engine, especially on roads that are congested with fluids. Some people think that automatic start-stop is unreliable, etc.

Therefore, there is no need to turn off the automatic start-stop at all.

The engine of a car equipped with automatic start-stop function is used 400,000 times, so it is said that it starts an average of 50 times a day, and it can be used for 2 years, which can have the same life as the car. As for the start-stop motor, the engineers of the car company have specially developed a motor with the help of the start-stop motor in order to work for a long time, and of course they will consider the number of uses, so that they don't have to worry about using it.

Engine start-stop technology refers to the automatic stopping of the engine when the vehicle is temporarily stopped while driving, such as waiting for a red light. When it's time to move forward, the system automatically restarts one of the engine's systems.

The start-stop system works when the vehicle stops due to a traffic jam or intersection. The driver presses the brake pedal and stops to engage gear. At this time, the start-stop system automatically detects:

The engine is idling, ungeared; The wheel speed sensor of the anti-lock braking system shows zero; The electronic battery sensor shows that there is enough energy for the next start. When these three conditions are met, the engine will automatically stop.

The working mode of the automatic start-stop system: as long as the brake pedal is directly pressed during driving, the engine will automatically turn off after the vehicle completely stops for about two seconds, and if the brake pedal is pressed all the time, the engine will remain off. As soon as you release the brakes or turn the steering wheel, the engine will immediately ignite automatically, and you can press the accelerator and start immediately, the whole thing is in the D position.

In order to solve the problem that the brakes are too tired all the time, as long as the Auto Hold electronic parking brake is also turned on, then the engine will only start after gently pressing the accelerator pedal, and the right foot does not need to press the brake all the time.

When the signal light turns green, the driver depresses the clutch and then it's time to start &ldquostarter &rdquo and start the engine quickly. The driver shifts gears and steps on the accelerator, and the vehicle starts quickly. With the support of high-efficiency battery technology and the corresponding engine management program, the start-stop system can work at low temperatures and can be started with only a short warm-up process.

Engine start-stop technology refers to the automatic stopping of the engine when the vehicle is temporarily stopped during driving. When it's time to move forward, the system automatically restarts one of the engine's systems.

The working principle is as follows: By implanting an enhanced motor with the start-stop function of Zhengzhou in the traditional lift-and-cover motor, when the vehicle meets the start-stop conditions, the engine will be completely extinguished and no longer work. When the whole vehicle needs to be started again, the idle start-stop motor system quickly responds to the driver's start command, quickly starts the engine, and is instantly connected, which greatly reduces fuel consumption and exhaust emissions.

Engine start-stop technology can reduce unnecessary fuel consumption, reduce emissions and improve fuel economy. When waiting for traffic lights or traffic jams in urban traffic, the idle idle time of the engine can be reduced as much as possible, and after the engine is turned off, its power supply can replace the pulley to provide operating power for the engine cooling fan and car air conditioning.

How to use the start-stop technology of the signal vertical motor: As long as you press the brake pedal directly while driving, the engine will automatically shut down after the vehicle has completely stopped for about two seconds, and if you keep pressing the brake pedal, the engine will remain off. As soon as you release the brakes or turn the steering wheel, the engine will immediately ignite automatically, and you can press the accelerator and start immediately, the whole thing is in the D position.
