How Does the Engine Start-Stop System Work?
1 Answers
Engine start-stop system working principle: When the vehicle comes to a halt due to traffic congestion or at an intersection, the driver depresses the brake pedal and shifts into neutral. At this point, the start-stop system automatically checks: the engine is idling and in neutral; the wheel speed sensors of the anti-lock braking system show zero rotation; and the electronic battery sensor indicates sufficient energy for a restart. Once these three conditions are met, the engine automatically shuts off. When the traffic light turns green, the driver presses the clutch pedal, which immediately activates the start-stop system and quickly restarts the engine. The driver then shifts into gear, presses the accelerator, and the vehicle promptly moves off. Supported by advanced battery technology and corresponding engine management software, the start-stop system can function effectively even at lower temperatures, requiring only a brief warm-up period to activate.
