What does the engine auto start-stop system mean?
2 Answers
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.
The auto start-stop system is really a great assistant in cars. I remember when I first started driving this car, I didn't quite understand what it meant. It automatically turns off the engine when you stop at a red light, helping me save fuel and money. During rush hour in the city, traffic is terrible with frequent starts and stops, but the system handles it automatically, saving me the trouble of manual operation. It adds up to saving hundreds of dollars on fuel each year—quite a bargain. Even better, it reduces exhaust emissions, making it environmentally friendly. Especially in summer, even when stuck in traffic, it doesn't get stuffy, and the air conditioning works normally without affecting comfort. The only minor annoyance is a slight vibration when starting up, but you get used to it after a few days. Overall, it feels quite practical and convenient. I recommend everyone use this feature—it's a win-win for energy savings and environmental protection.
