What does engine start-stop mean?
2 Answers
Engine start-stop is a very practical automotive energy-saving and emission-reduction technology. It automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. Below is a detailed explanation of engine start-stop: 1. At a red light: The system can automatically shut off the engine, and when the car needs to move forward again, the system can automatically restart the engine. 2. The main function of the engine: To increase pressure and improve air intake, aiming to achieve high power output and make the car more powerful.
I recently noticed that many new cars have this feature while driving, especially in congested urban traffic, which is particularly practical. The engine start-stop system means that when your car comes to a complete stop, such as at a red light or in traffic, the system automatically shuts off the engine to save fuel. As soon as you release the brake or press the accelerator, it instantly restarts the engine, allowing you to continue driving. This design primarily aims to reduce fuel consumption and exhaust emissions during idling. For example, in environmental tests in Europe and the U.S., this feature can help vehicles reduce fuel consumption by 5% to 10%. Personally, I find it quite convenient, especially for saving on fuel costs in the long run, though it might feel a bit unfamiliar at first, such as the slight vibration when the engine restarts. However, most cars now have optimized systems that operate very smoothly. It's recommended to check the health of the starter and battery during maintenance.
