What does engine start-stop mean?

[KylieLynn]

Engine start-stop refers to a system that can automatically shut off the engine when the vehicle comes to a temporary stop during driving, such as waiting at a red light. When the car needs to move forward again, the system can automatically restart the engine. Features of start-stop technology: In ordinary start-stop technology, the engine automatically turns off when the car encounters a red light or traffic jam. When the driver releases the brake pedal or steps on the clutch (or accelerator pedal), the engine promptly restarts on its own. More complex start-stop systems also include brake energy recovery functionality, which can convert part of the energy from the braking process into electricity to charge the battery. Functions of engine start-stop: It is used when the car is moving at low speeds or repeatedly stopping, helping to automatically shut off the engine to avoid unnecessary fuel consumption. It also reduces the car's idle time, which in turn decreases engine carbon buildup, benefiting both environmental protection and the engine's lifespan.
