What is engine start-stop technology?

 

The engine start-stop is to automatically turn off the engine when the vehicle is temporarily stopped (for example, waiting for a red light) during the driving process. A system that automatically restarts the engine when it's time to move on.

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. According to reports, this system can achieve 15% fuel-saving capacity in urban conditions.

The driver sits in the cockpit, the red light at the intersection ahead lights up, the driver depresses the brake pedal, stops and picks up gear. At this time, the Start/Stop system automatically detects: the engine is idling and not in 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 stops automatically.

When the signal light turns green, the driver depresses the clutch, and the "start stopper" can be activated immediately, and the engine can be started quickly. The driver shifts the gear, steps on the accelerator, and the vehicle starts quickly. Supported by efficient battery technology and a corresponding engine management program, the start-stop system works well even at lower temperatures and requires only a brief warm-up process to activate.
