How Does the Engine Start-Stop System Work?

[SanArcher]

The working principle of the engine start-stop system is: 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 there is sufficient energy to restart. Once these three conditions are met, the engine automatically stops turning. The engine start-stop system is a set of mechanisms 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 is time to move forward again.
