What is the Auto Stop-Start Function?
2 Answers
The auto stop-start function is an engine auto start-stop feature, which has the following characteristics: 1. The engine can automatically shut off to reduce fuel consumption and emissions; 2. After the engine shuts off, the power supply can replace the pulley to provide operating power for the engine cooling fan and in-car air conditioning. Precautions for using auto start-stop include: 1. Quickly shift to P gear when the engine stops and release the brake; 2. Reduce current consumption; 3. Do not repeatedly press the brake when the engine is off; 4. Wait for the engine speed to drop to zero, engage the starter gear, and then restart; 5. Do not activate the auto start-stop system during low-speed parking or when the air conditioning is on.
When you stop at a red light while driving, the engine suddenly becomes quiet and shuts off automatically—this is the auto start-stop function. I've driven many cars equipped with this system, which relies on sensors and a control unit working together. The engine shuts off to save fuel once the car comes to a complete stop, and restarts instantly when you release the brake pedal to accelerate, reducing fuel consumption by about 10%. It's particularly effective for urban traffic in terms of environmental benefits. However, there's a slight vibration during restart, and it places higher demands on the battery. High-end models even integrate smart systems to optimize response speed, achieving both fuel efficiency and quiet operation.
