What Causes an Engine to Stall Automatically?
2 Answers
Reasons for an engine stalling automatically: 1. Electrical circuit failure, which can cause the engine to stall due to low-voltage power interruption while driving. It is recommended to primarily inspect the ignition and starter switch, as well as the fuse box. 2. Low-voltage circuit short circuit leading to stalling. In this case, the stalling occurs intermittently, and it is necessary to check the vehicle's low-voltage circuits. The car engine is the device that provides power to the vehicle, determining its power performance, fuel economy, stability, and environmental friendliness. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid power systems, among others.
My beloved car suddenly stalled on the highway once, giving me a cold sweat. Common causes include fuel system issues, such as a non-working fuel pump leading to interrupted fuel supply, or a clogged fuel filter causing poor fuel flow; ignition system failures like excessive carbon buildup on spark plugs causing ignition failure, or a short circuit in the ignition coil; electrical problems such as insufficient alternator output or an aging battery unable to supply power; sensors like a faulty crankshaft position sensor making the computer unable to determine the position, leading to random stalling; and intake leaks or a dirty air filter, making the engine struggle to breathe and prone to stalling. It's recommended to regularly change the oil and filters, avoid immediately restarting the engine after stalling, turn on hazard lights, pull over to check, or tow it to a professional shop for repairs—safety always comes first.
