The auto start-stop system saves fuel, and here are the reasons: 1. Definition: The auto start-stop system, known as STOP&START or STT in English, is an intelligent fuel-saving system that controls the engine's start and stop functions. 2. Principle: The auto start-stop system enhances the traditional engine with a reinforced motor that enables idle start-stop functionality. When the vehicle meets the conditions for idle stop, the engine shuts off completely. When the vehicle needs to move again, the idle start-stop motor system quickly responds to the driver's command, restarting the engine instantly and seamlessly, thereby significantly reducing fuel consumption and exhaust emissions.
