What is the purpose of auto start-stop in cars?
2 Answers
The functions of auto start-stop in cars are: 1. When the vehicle stops due to traffic congestion, waiting at a red light, or temporary parking, the driver presses the brake pedal and shifts to neutral. The vehicle remains stationary, and the auto start-stop system initiates a self-check. 2. If it detects that the engine is idling and not in gear, the wheel speed sensor reads zero, and it continues to check whether the vehicle has sufficient battery power for the next start. The working principle of auto start-stop is: When braking to stop and shifting to neutral, the system automatically detects that the engine is idling and not in gear, the speed sensor shows zero, and the battery sensor indicates sufficient energy. The engine automatically stops running. Upon pressing the clutch, releasing the brake, or turning the steering wheel, the system quickly restarts the engine.
I previously drove a car with a start-stop system, which automatically shuts off the engine during brief stops, such as at red lights or in traffic jams, to save fuel, and instantly restarts when needed. This feature helped me save a lot on fuel costs, reducing my urban commuting fuel consumption by about 10%. The engine shutdown also reduced emissions, making it environmentally friendly. Although there was a slight vibration when the engine restarted initially, I got used to it and found it quite smooth. This design minimizes idling losses, extends engine life, and makes driving quieter. The only minor drawback is that the air conditioning cooling pauses for a few seconds in summer, but overall, the experience is positive, especially in congested areas, helping me save money and support sustainability. Highly recommended.
