Does Secondary Ignition Affect the Car?
2 Answers
If the vehicle is ignited again while it is already running, repeated secondary ignition can cause certain damage to the starter and ignition coil. However, if it happens occasionally by accident and the duration is short with few occurrences, it won't cause significant harm. It is recommended to avoid such situations as much as possible in the future. Below is an introduction to the starter: 1. Function of the starter: The starter converts electrical energy into kinetic energy when the key is turned to the ignition position, thereby starting the engine. 2. Components of the starter: The small cylindrical part at the top is the starter solenoid, which functions to push the gear forward to engage the starter gear with the engine's flywheel; the large cylindrical part at the bottom is the starter motor, which provides the torque needed to start the engine.
A second start can indeed affect the car. I often maintain my vehicle myself and have seen many cases. When the engine is restarted immediately after stalling, it may cause the starter to work repeatedly, leading to overheating and damage; the battery also discharges quickly, especially noticeable in winter or older cars, shortening the battery's lifespan. I've also observed that frequent operation like this increases fuel consumption because the engine requires more fuel to warm up during a cold start. If you encounter this situation, check if the car's sensors are malfunctioning, such as a faulty thermometer. Developing good habits, like waiting a few dozen seconds after stalling before restarting, can reduce mechanical wear. During regular maintenance, pay attention to the starter's condition—repairing it can be quite expensive if it burns out.
