What are the benefits of engine start-stop?

[BradleyFitz]

Engine start-stop benefits include energy conservation and emission reduction. When the engine start-stop function is activated, the engine enters a temporary dormant state, eliminating the issue of instantaneous fuel consumption and saving fuel. The working principle of the engine start-stop system is that when the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal, stops, and shifts into neutral, at which point the system automatically detects the conditions. Generally, the automatic start-stop technology is enabled by default after the ignition is turned on. If it needs to be turned off, a simple press of a button is sufficient. When in use, it is more convenient. During driving, as long as the brake pedal is pressed and the vehicle comes to a complete stop for two seconds, the engine will automatically shut off. If the brake remains pressed, the engine will stay off.
