Advantages and Disadvantages of Engine Auto Start-Stop System

[GabriellaLynn]

The engine auto start-stop system has the following advantages and disadvantages: 1. Advantages of the auto start-stop system: The engine auto start-stop function automatically shuts off the engine when the vehicle stops at a traffic light (after pressing the brake pedal for three seconds), putting the engine in an off state. When the light turns green, releasing the brake pedal automatically restarts the engine, allowing the vehicle to shift gears and drive. This feature benefits fuel efficiency by shutting off the engine during stop-and-go traffic when conditions are met, thereby reducing fuel consumption and exhaust emissions. 2. Disadvantages of the auto start-stop system: The auto start-stop function places stringent demands on the battery. Consequently, vehicles equipped with this feature typically have larger batteries. It also requires higher-quality starter motors, leading to slightly higher maintenance and repair costs in the long run.
