Impact of Start-Stop Technology on Engines?

[StEmily]

Start-stop technology causes the engine to start and stop frequently, but the impact on the engine itself is minimal. With proper maintenance, the wear and tear from repeated starts and stops are negligible. Below is an introduction to start-stop technology: 1. Function: During traffic congestion or at red lights, the engine can shut off to save fuel that would otherwise be wasted during idling. When ready to drive, the engine restarts immediately. 2. Advantages: Reduces unnecessary fuel consumption, lowers emissions, and improves fuel economy. In urban traffic, when waiting at traffic lights or in traffic jams, it minimizes engine idling time. Additionally, after the engine shuts off, the electrical system can replace the belt-driven power for the engine cooling fan and cabin air conditioning. 3. Disadvantages: Requires more durable starters and high-quality engine oil. Conventional starter designs allow for high operating currents but are used for very short durations. Frequent use of the starter can lead to overheating and damage, so starters with automatic start-stop functionality must be significantly more durable than standard starters.
