The meaning of the car engine start-stop technology is: a system that automatically shuts off the engine when the vehicle needs to temporarily stop during driving and automatically restarts the engine when it is time to move forward again. The method of car start-stop is: 1. When encountering a red light or other reasons to stop while driving, the engine automatically shuts off after stepping on the brake; 2. When starting again, simply release the brake and step on the accelerator or gently turn the steering wheel, and the engine will restart. The principle of the start-stop technology is: when stopping by stepping on the brake and shifting out of gear, the system automatically detects that the engine is idling and not in gear, the speed sensor shows zero, the battery sensor shows there is energy, and the engine automatically stops rotating. When stepping on the clutch, releasing the brake, or turning the steering wheel, the system will quickly start the engine.
Engine start-stop technology means that when the car is waiting at a traffic light or briefly stopped, for example, when you firmly press the brake, the system will automatically turn off the engine to avoid idling. When you're ready to go, releasing the brake or pressing the accelerator will immediately restart it. I drive a sedan equipped with this feature, running daily in the city, and it saves quite a bit on fuel—estimated to save hundreds in fuel costs over a year. It's especially useful during traffic jams; with the engine off, there's no noise or exhaust, making the city air fresher. At first, I was a bit bothered by the slight jerk during startup, but you get used to it. This little technology relies on sensors and a reinforced battery, not too complex, but the effect is significant—saving fuel and being eco-friendly. I recommend all car owners give it a try, especially on frequently congested roads—it's truly worth it!
