What is Engine Start-Stop Technology?
2 Answers
Engine start-stop technology is a system that automatically shuts off the engine when the vehicle comes to a temporary stop during driving (such as waiting at a traffic light). When it's time to move forward again, the system automatically restarts the engine. Here is more information: How the Start-Stop System Works: When the vehicle stops moving due to traffic 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 there is enough energy for the next start. Once these three conditions are met, the engine automatically stops running. Operation of the Automatic Start-Stop System: While driving, simply pressing the brake pedal will cause the engine to automatically shut off about two seconds after the vehicle comes to a complete stop. As long as the brake pedal is held down, the engine remains off. Releasing the brake pedal or turning the steering wheel will immediately trigger the engine to restart automatically, allowing the driver to press the accelerator and start moving again—all while remaining in Drive (D) mode.
The engine start-stop technology, simply put, means the car automatically shuts off when waiting at a red light or in traffic, and restarts when you release the brake or press the accelerator, saving fuel and being eco-friendly. I found this function mainly relies on sensors and computer control. For example, when the car comes to a complete stop, is in neutral, and the battery has sufficient charge, the system turns off the engine; when it's time to move, it restarts immediately. Many people find the startup sound a bit annoying, but for city driving, long-term use can save a lot on fuel costs and reduce emissions, especially when paired with a hybrid system, the effect is even more impressive. Although some say frequent starts might harm the engine, with today's mature technology, this is hardly an issue, making it quite convenient to use.
