Does the automatic start stop system save fuel?

Engine start-stop technology is fuel-efficient. The method of starting and stopping the engine is as follows:

1. Normally, as long as the vehicle is started, the automatic start-stop system is in normal working condition;

2. When you drive at a traffic light or stop for other reasons, step on the brake, and the engine will automatically turn off after two seconds;

3. Then if you want to go, release the brake and press the accelerator, or gently turn the steering wheel, and the engine will start again.

A large number of tests have proved that after turning on the automatic start and stop, it can save about 8%-15% of fuel on the road. However, some car owners have raised questions: if the road conditions are too bad, the start and stop time is very short and frequent, will the fuel consumed by the car start more than not turning off the engine?

In fact, after the automatic start-stop takes effect, the engine is still in a state of "high temperature" because it has just stopped working, so when it is restarted, the resistance is relatively small. Studies have shown that in such a state, the fuel consumption of the engine starting is only equivalent to the fuel consumption of seconds in the idle state, so in theory, stopping for more than 1 second can save fuel.

I can save fuel! Turn on the automatic start and stop, the driving computer will automatically judge the state of the vehicle, and without affecting the safety of the vehicle and the comfort of the ride, realize the automatic start-off of the engine, thereby reducing unnecessary fuel consumption and emissions in the case of engine idling.

When does auto-start-stop work?

When a series of conditions are met, such as the engine reaches a certain temperature, the battery is sufficient, the doors are closed, and it is not on a very steep uphill or downhill road, and the brakes need to be applied to make the vehicle close to a stop or completely stopped, the engine will automatically turn off. When the engine is turned off, the engine will automatically start when safety or comfort requirements cannot be met, such as excessive heating or cooling in the car, voltage drop in the car's battery, steering wheel turning, etc.

Most models are now equipped with automatic start-stop, but some people feel that this feature affects the driving experience, or does not feel the fuel saving effect. But you know what? Auto-start and stop actually really helps to save fuel.

On the contrary, it is more fuel-guzzling, and many of the devices on the car are very weak and cannot be used.

Automatic start-stop can indeed save fuel in principle and practice, but it does not save money. Because the automatic start and stop will have some damage to the engine of the car and some devices of the car, the frequent use of automatic start and stop can save fuel, but it will also cause some damage to the car. The most important thing is that this automatic start-stop device will affect the car owner's car experience, and many car owners will also turn off these automatic start-stop devices when they encounter a large traffic jam.

It can be seen that the automatic start-stop device is not always practical when it is practical, although it can reduce fuel consumption, but in the eyes of the division machine, it is not a pleasing device.

All in all, the automatic start-stop system does reduce fuel consumption. This is because the automatic start-stop device can make the car's engine sleep at the right time, reducing fuel consumption, but it does not mean that it is enough to save money.

Really fuel-efficient; Because the automatic start and stop is only to let the car be in a state of shutdown, the planning machine does not completely stop the task, the owner starts again, the planning machine can quickly restore the situation before the revival, so it is very fuel-efficient.

It's really fuel-efficient; Because the automatic start-stop only keeps the car temporarily in a state of shutdown, the engine does not completely stop working, the owner starts again, and the engine can quickly return to the previous state, so it is very fuel-efficient.

It's really fuel-efficient; This is because automatic start-stop can reduce fuel consumption caused by idling, but it can lead to accelerated engine wear.

Of course. Because the function of automatic start and stop can reduce the fuel consumption of the car at idle, so as to achieve the purpose of fuel saving.

Automatic start-stop fuel saving.

Automatic start-stop can indeed save fuel, but the saved fuel money is almost enough to replace the start-stop special battery, and it will indeed increase the wear and tear of the engine. Automatic start-stop can indeed save fuel, but not money, the automatic start-stop function is developed to reduce fuel consumption at idle, it is indeed able to save fuel, and it is also helpful for environmental protection.

Sun Tao published in the journal "Automotive Practical Technology", "Start-stop System Control and System Application". As mentioned above, when the car is in a traffic jam or stops at a red light, the control device will automatically turn off the engine.

The start-stop system can reduce fuel consumption and emissions by about 8% under comprehensive working conditions, and the energy saving effect can reach 10% to 15% in congested urban areas.

Automatic start and stop

The automatic start and stop of the engine is to automatically turn off the engine when the vehicle is temporarily stopped during driving. When it's time to move on, the system automatically restarts the engine. English name:stop&start, referred to as intelligent fuel-saving system, is a set of control engine start and stop system.

It is by implanting a reinforced motor with an idle start-stop function in the traditional engine, so that the engine is completely extinguished and does not work when the car meets the idle stop conditions. When the whole vehicle needs to start and move forward, the idle start-stop motor system quickly responds to the driver's start command, quickly starts the engine, and connects instantaneously, thereby greatly reducing fuel consumption and exhaust emissions.

The engine automatic start-stop system is fuel-saving, and the engine automatically starts and stops, and the English name stop&start is referred to as the intelligent fuel-saving system, which is a system that controls the start and stop of the engine. The engine can be started quickly and connected instantly, which greatly reduces fuel consumption and exhaust emissions. The advantages and disadvantages of the automatic start-stop system are as follows

Advantages of the automatic start-stop system:

Fuel-saving, although the process from the shutdown to the start of the section beam is very short, but it can still help the owner save about 10% of gasoline. This function usually looks inconspicuous when waiting for traffic lights, but when it is approaching holidays or when there is a traffic jam on a rainy day, all car owners will be deeply aware of it. During rush hour, they would stay on the road for half an hour.

At this time, the automatic start-stop function can help the car owner save a lot of fuel.

Disadvantages of the automatic start-stop system:

As the cost of cars increases, cars with automatic start-stop systems are a little more expensive than those without this technology. In addition, due to the frequent and repeated engine starts and stops, the requirements for oil quality are high. In places where traffic jams are normal, the formation of carbon deposits and the maintenance cost of batteries and starters increase, and as a result, the oil saved is not enough to replace batteries and repair starters.

At the same time, there is also a common problem, that is, the engine should be turned off when it should not be turned off, and sometimes the car will keep shaking when it stops and goes.
