Engine start-stop technology

As the name implies, the engine start-stop system automatically turns off the engine when the vehicle stops temporarily (for example, waiting for a red light) during driving. When it is necessary to continue driving, the system will automatically restart the engine.

For models equipped with automatic transmission, the working principle of the automatic start-stop system is as follows:
As long as the brake pedal is directly depressed during driving, the engine will automatically turn off about two seconds after the vehicle is completely stopped. If you continue to step on the brake pedal, the engine will remain off. As long as the brake is released or the steering wheel is turned, the engine will automatically ignite again, and the throttle can be started again immediately, and the whole process is in the D gear state.
In order to solve the problem of too tired to step on the brakes, as long as the AUTOHOLD electronic handbrake is turned on at the same time, the engine will only lightly step on the accelerator in the Mercedes-Benz)
After the board is activated, the right foot does not need to be on the brake all the time.
or vibration

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. It is estimated that by 2012, 50% of newly launched cars in Europe will be equipped with start-stop systems. According to reports, the system can achieve 15% fuel saving capacity under urban road conditions.
The working principle of engine start-stop technology
The working principle of the start-stop system is when the vehicle stops due to congestion or intersection. The driver depresses the brake pedal, stops and shifts into gear. At this time, the start/stop system will automatically detect: the engine is idling and not in gear; the wheel speed sensor of the anti-lock brake 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 stops automatically.
When the signal light turns green, the driver steps on the flameout device to start the "start stop" and quickly start the engine. The driver enters the gear, depresses 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 also work normally at low temperatures and can be started after a short warm-up process.

Instructions for use

As long as the brake pedal is directly depressed during driving, the engine will automatically turn off about two seconds after the vehicle is completely stopped. If you continue to step on the brake pedal, the engine will remain off. As long as the brake is released or the steering wheel is turned, the engine will automatically ignite again, and the throttle can be started again immediately, and the whole process is in the D gear state.
