Engine start-stop technology pros and cons: The advantages include reducing unnecessary fuel consumption, lowering exhaust emissions, improving fuel economy, and being more environmentally friendly; The disadvantage is that this technology is not universal and is more suitable for more durable engines and high-quality engine oil. General engine design allows for large operating currents, but the usage time is relatively short, and repeated use can easily cause engine overheating and damage. Engine start-stop technology refers to the technology that automatically shuts off the engine when the vehicle needs to temporarily stop during driving, and can automatically restart the engine when it is time to continue driving.
My car also has the start-stop function. When driving in the city and stopping at red lights, the engine automatically shuts off, which is quite fuel-efficient. It saves about 10 to 20 yuan on gasoline per month, a small benefit. The downside is that there's often a slight vibration during startup, making it feel less smooth, especially noticeable in older car models, which can unsettle new drivers. Additionally, frequent start-stop cycles can accelerate wear on the starter and battery, shortening the battery's lifespan—replacing it costs several hundred yuan. In summer, when the car is stopped, the air conditioning airflow weakens, making the interior stuffy; in winter, the heating isn't as strong either. Overall, fuel savings and environmental friendliness are highlights, but it's important to regularly check the battery's condition. Using a specialized AGM battery can make it more durable, and avoiding long-term frequent use can prevent premature repairs.
