Does secondary ignition affect the car?

[IsabelaAnn]

Secondary ignition does affect the car. Frequent secondary ignition can cause damage to the starter motor, starter engagement gear, and the flywheel ring gear of the engine. Here are the specific details about secondary ignition in cars: 1. Reason: After the engine starts, the starter will stop working. Sometimes, due to factors such as the engine sound being relatively quiet or the engine running smoothly after starting, many car owners may mistakenly believe that the engine has not started and proceed with a secondary ignition operation. 2. Symptoms: The flywheel ring gear on the rear end of the engine crankshaft will engage with the gear on the motor shaft again, causing a sharp metallic collision sound as the high-speed rotating flywheel ring gear meshes with the stationary gear on the motor shaft. The flywheel ring gear rotates much faster than the starter gear when the engine is running. Due to this speed difference, secondary ignition will not cause the starter drive gear to re-engage with the flywheel teeth, thus avoiding the risk of the starter being damaged.
