What is the Engine Start-Stop Function?
2 Answers
Engine start-stop function is: when encountering a red light, stepping on the brake pedal causes the vehicle to stop, and after three seconds, the engine automatically shuts off, entering an idle state; when the light turns green, lifting the brake pedal automatically starts the engine, allowing the vehicle to engage gear and drive. Under automatic start-stop operating conditions, shutting off the engine can save fuel and reduce exhaust emissions. The working principle of the start-stop system is that when the vehicle stops moving due to congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the start-stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates sufficient energy for the next start. After these three conditions are met, the engine automatically stops running.
The engine start-stop function is a real eco-friendly helper in my daily driving. Simply put, when you stop at a red light or in traffic, it automatically turns off the engine; when you release the brake to move, it quietly restarts the engine to keep going. This significantly reduces unnecessary fuel consumption and exhaust emissions. I've observed that in the city, every short stop saves fuel, and on average, using this feature has reduced my refueling frequency by nearly 10%. For the environment, reducing carbon footprint is a good thing, especially with the current severe air pollution issues. It also operates quietly, with no noticeable vibrations during startup, ensuring comfort isn't compromised. Over time, fuel bills decrease, and the car becomes cleaner and more environmentally friendly. I think this technology is suitable for anyone looking to save money and love the planet.
