What does engine start-stop technology mean?

[SanAdeline]

Introduction to the meaning of engine start-stop technology: Engine start-stop technology refers to the automatic shutdown of the engine when the vehicle comes to a temporary stop during driving (e.g., at a red light). When it's time to move forward again, the system automatically restarts the engine. Here are more details: 1. The working principle of the start-stop system is that when the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates sufficient energy for the next start. Once these three conditions are met, the engine automatically stops. 2. The operation of the automatic start-stop system is as follows: while driving, as soon as the brake pedal is pressed directly and the vehicle comes to a complete stop for about two seconds, the engine will automatically shut off. As long as the brake pedal is held down, the engine remains off. As soon as the brake is released or the steering wheel is turned, the engine automatically restarts immediately, allowing the driver to press the accelerator and start moving again, all while remaining in D gear.
