What are the advantages and disadvantages of the auto start-stop function in cars?

[DiLukas]

The advantages and disadvantages of the auto start-stop function in cars are as follows: 1. Advantages and reasons: The principle of the auto start-stop system is to add an electric motor to the common gasoline engine. When the car is stopped and the engine is idling, the engine will completely shut off. When it is necessary to start, the electric motor quickly starts the engine by the driver stepping on the accelerator pedal, clutch, or turning the steering wheel, achieving seamless transition and thereby reducing fuel consumption during idling. 2. Disadvantages and reasons: (1) Frequent engine starts and stops can cause damage to related components such as the starter and battery. Although vehicles equipped with auto start-stop systems use enhanced starters and batteries, in actual use, their failure rates are higher than those of ordinary vehicles without auto start-stop systems. (2) The maintenance costs of enhanced starters and batteries are higher than those of ordinary starters and batteries. Additionally, due to the frequent repeated starts and stops of the engine, there is a higher demand for oil quality, further increasing maintenance costs.
