What does the auto start-stop function in a car mean?

Engine auto start-stop is 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. Its English name is STOP&START, abbreviated as STT. The STT intelligent fuel-saving system is a set of controls for engine start and stop. Working principle of the start-stop system: 1. 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 detects: the engine is idling and not in gear; the wheel speed sensor of the anti-lock system shows zero; the electronic battery sensor indicates sufficient energy for the next start. 3. Once these three conditions are met, the engine automatically stops. When the traffic light turns green, the driver presses the clutch, and the 'start stopper' can be activated immediately, quickly restarting the engine.
When driving a car with auto start-stop function, the engine automatically shuts off when stopped and restarts when moving again. This system is achieved through sensors monitoring your driving conditions. For example, at red lights or in traffic jams, the engine turns off to save fuel and reduce emissions, typically cutting consumption by 5%-10%. I find it not only efficient but also environmentally friendly as it lowers CO2 emissions. Don’t worry about restart delays – modern cars feature quick-start technology for near-instant response. However, in some older vehicles, the battery may bear heavier loads, making regular maintenance crucial. Overall, it makes driving more economical and eco-friendly, and I recommend enabling it for urban driving.
I think the auto start-stop system is when the car turns off the engine at stops to reduce waste, and automatically restarts when moving, which is very eco-friendly! It helps me reduce exhaust emissions, especially in urban traffic congestion, cutting carbon emissions by about 10%. This is like a small contribution to combating climate change, and I love supporting this technology because it promotes sustainable development. Although some complain about the startup noise, in the long run, it saves fuel and reduces pollution. Remember, combining it with reasonable driving habits, like avoiding sudden braking, can make the environment even friendlier.
