Does the Auto Start-Stop Function Damage the Engine?

[CoraRose]

Engine start-stop function does not damage the engine. Here are the relevant explanations: 1. Reason: Most wear on car engines comes from instantaneous wear during cold starts, which relies on oil film lubrication inside the engine. Auto start-stop durations are very short, and the oil pumped up by the oil pump to adhere to the inner surface of the engine cylinder does not completely flow back, leaving plenty of oil on the components. Under hot start conditions, it has no significant impact on the engine. 2. Endurance testing: Currently, the vast majority of automotive manufacturers conduct thorough endurance tests when introducing auto start-stop systems, including testing the number of switch cycles for components such as engine ignition switches and starters.
