Smooth Operating Condition Switching: The start-stop operating condition switching process is smooth and gentle, without instantaneous current surges or sudden power changes, ensuring a smooth transition between the engine and electronic control system. This feature automatically shuts off the engine when the vehicle comes to a temporary stop—such as at a red light or in a traffic jam—and quickly restarts it when the brake is released or the accelerator is pressed. Its purpose is to save fuel and reduce exhaust emissions. The primary function of the engine start-stop switch is to enable or disable the automatic start-stop system.
