What is the Principle of Engine Start-Stop Technology?

[NaomiLynn]

Engine start-stop technology principle: 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 detects that the engine is idling without gear engagement, the wheel speed sensors of the anti-lock braking system show zero, and the electronic battery sensor indicates sufficient energy for restarting. Once these three conditions are met, the engine automatically stops rotating. Engine automatic start-stop is a system that automatically shuts off the engine when the vehicle temporarily stops during driving (such as waiting at a red light) and automatically restarts the engine when it's time to move forward again.
