What does the engine auto start-stop system mean?

[DelMadelyn]

Engine auto start-stop system: A system that automatically shuts off the engine when the vehicle comes to a temporary stop (such as waiting at a red light) during driving, and automatically restarts the engine when it's time to move forward again. Advantages and disadvantages of the engine auto start-stop function: 1. Advantages: It can reduce unnecessary fuel consumption, lower emissions, and improve fuel economy. In urban traffic when waiting for traffic signals or during traffic jams, it can minimize engine idling time. Additionally, after the engine shuts off, its power supply can replace the belt pulley to provide operating power for the engine cooling fan and in-car air conditioning. 2. Disadvantages: It requires more durable starters and batteries. Conventional starter designs allow for high operating currents but are intended for very short usage periods. Repeated use of the starter can easily cause overheating and damage. Therefore, starters with auto start-stop functionality must be significantly more durable than regular starters.
