What is Engine Start-Stop Technology?
2 Answers
Engine start-stop technology refers to a system that automatically shuts off the engine when the vehicle comes to a temporary stop during driving (such as waiting at a red light). When it's time to move forward again, the system automatically restarts the engine. More information about vehicle start-stop systems is as follows: 1. The working principle of the start-stop system is that when the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. 2. The Start/Stop system automatically checks: the engine is idling and in neutral; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates there's enough energy for the next start. When these three conditions are met, the engine automatically stops running.
Engine start-stop technology automatically shuts off the engine when the vehicle comes to a stop, such as at red lights or in traffic jams, helping you save fuel. Once you release the brake or press the accelerator, it quietly restarts the engine, allowing the car to move immediately. This feature primarily relies on onboard sensors to detect position and speed changes, combined with a robust battery and starter motor system. The design is quite intelligent, ensuring a smooth restart process without abruptness. I've driven cars with this feature, and it does save a significant amount of fuel in city driving, averaging 5% to 10% savings per liter. However, there can be a slight vibration during restart, unlike the smoother experience in older cars. Overall, it improves driving efficiency and reduces emissions, making it ideal for stop-and-go traffic. When buying a used car, remember to check the system's condition to avoid malfunctions caused by faulty sensors. For maintenance, it's best to regularly check the battery lifespan, as repeated starts can increase wear.
