What are the effects of secondary ignition?

[JasonLee]

Secondary ignition can cause certain damage to the starter motor and ignition coil. Here is the relevant content introduction: 1. Reason: Starting the car again when it is already running will cause the starter motor to grind gears, generally causing damage to the starter gear of the starter motor and the flywheel ring gear of the engine. However, this damage is only limited to the flywheel ring gear and the starter pinion, and the starter will experience excessive local wear, but it will not harm important components such as the engine and transmission. 2. External force system: In order to bring the stationary engine into working condition, it is necessary to first rotate the engine crankshaft with an external force to make the pistons start moving up and down, allowing the cylinder to inhale combustible mixture gas, and then sequentially enter the subsequent working cycles. The system that relies on this external force is the starting system.
