Does the Start-Stop Function Stop the Engine?

Start-stop function stops the engine. Below is relevant information about the start-stop function: 1. Function: The purpose of automatic start-stop is: when the vehicle is in motion and needs to stop, the engine will automatically shut off; when ready to move again, simply depress the clutch and the engine will automatically restart, saving time. 2. Working Principle: The working principle of the start-stop system is: when the vehicle needs to stop due to traffic congestion or at intersections, the driver can press the brake pedal and shift to neutral. At this point, the Start/Stop system automatically checks if the following conditions are met: the engine is idling and in neutral, the wheel speed sensors of the anti-lock system show zero rotation, and the electronic battery sensor indicates sufficient energy for another start. The entire process remains in D gear.
I've driven quite a few cars with start-stop systems, and they do shut off the engine. When you brake at a red light or in traffic, the system detects the vehicle is stationary and automatically turns off the engine to save fuel; releasing the brake or pressing the accelerator quickly restarts it. This feature is quite common in city driving, saving me dozens in fuel costs monthly, though sometimes the restart can be a bit jerky, especially in older cars. The battery is crucial—it needs to stay healthy, or the system might fail. Over time, I've found it great for the environment, reducing exhaust emissions. I'd recommend new car owners give it a try, but don't forget regular maintenance.
