What is the Engine Start-Stop Function?
2 Answers
The engine start-stop function is a system that automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts it when it's time to move forward again. The correct way to use the auto start-stop is: 1. Press the 'on' button next to the start button to activate the start-stop function; 2. Shift to D gear, press the brake to stop, and the engine will automatically shut off; 3. Release the brake, and the engine will automatically restart. The correct parking steps for auto start-stop are: 1. For automatic transmission vehicles, press the brake, and the engine will usually shut off automatically after two seconds; 2. For manual transmission vehicles, shift to neutral, then pull the handbrake and release the clutch. The system will automatically shut off the engine after recognizing these three actions.
The engine start-stop function automatically shuts off the engine when I come to a stop, such as at a traffic light, to save fuel and reduce emissions. After the engine stops, it quickly restarts as soon as I release the brake or press the accelerator. This system relies on sensors and computer control to ensure it operates only under safe conditions, such as zero vehicle speed, sufficient battery charge, and appropriate temperature. The advantages are obvious—it helps me save a significant amount on fuel costs, reducing urban driving fuel consumption by up to 10%. The downside is that the restart can sometimes cause a slight vibration, but modern cars are equipped with durable starter motors and batteries designed to withstand frequent use without harming the engine. Overall, this system enhances driving efficiency, especially during daily commutes with frequent stops, making the car more environmentally friendly.
