Does accidentally restarting the engine cause damage?
2 Answers
Accidentally restarting the engine can cause certain damage to the starter motor and ignition coil. When the engine is already running, restarting it will cause the starter motor to grind, typically damaging the starter gear of the starter motor and the flywheel ring gear of the engine. However, this damage is limited to the flywheel ring gear and the starter pinion, leading to excessive wear on the starter components, and does not affect critical parts like the engine and transmission. Relevant information about the engine is as follows: 1. Introduction: The car engine is the device that provides power to the vehicle, serving as the heart of the car. It determines the vehicle's performance, fuel efficiency, stability, and environmental friendliness. 2. Classification: Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others.
I once accidentally started the car while the engine was already running. That day I was a bit distracted, and after starting the car, I turned the key again, which resulted in a loud grinding noise. Later, I asked a mechanic friend about it, and he said doing it occasionally isn’t a big problem, but frequent occurrences can wear out the starter gear and flywheel ring gear, potentially leading to the failure of the starting system. Modern cars usually have protective mechanisms to prevent damage, but you shouldn’t rely entirely on them. It’s best to confirm the tachometer is moving or listen for the engine sound before starting. If it does happen, pay attention to any unusual noises and promptly visit a repair shop to inspect and replace parts to prevent major issues.
