What does the auto start-stop function in a car mean?
2 Answers
Auto start-stop is a feature where the vehicle automatically shuts off the engine when temporarily stopping, such as at traffic lights, and restarts when you continue driving. Proper use of this function can help save fuel. Below is additional information about auto start-stop: 1. Fuel saving: Using auto start-stop can save up to 5% of fuel, with savings reaching up to 15% in congested areas. However, during peak urban traffic hours, it is recommended to turn off the auto start-stop function, as each restart consumes 3-5 seconds of idle fuel, potentially increasing fuel consumption. 2. Impact on the engine: Auto start-stop can cause some wear to the engine, but most engine wear occurs during cold starts. During normal driving, auto start-stop operates in a hot-start environment, where the engine is temporarily shut off for short stops. Since the engine is already warm, the wear is minimal. Additionally, the engine oil is less viscous and more fluid, making it easier to coat components and reduce wear caused by the auto start-stop function.
The auto start-stop is a fuel-saving feature I use daily while driving. Simply put, it automatically shuts off the engine when I'm waiting at a red light or stuck in traffic, and instantly restarts it when I release the brake. I think it's pretty smart because I live in a big city with frequent traffic jams, and the system helps reduce idle fuel consumption. According to tech experts, it can save 5-15% on fuel. At first, I wasn't used to it—the engine start-stop would cause a slight vibration—but now I've adapted and find it quite comfortable. The key is to ensure the car's battery is healthy, as the system relies on battery power for quick starts. Overall, it's eco-friendly and cost-effective, but if you do a lot of short trips, it's advisable to turn it off occasionally to avoid draining the battery.
