Why does a car stall while driving?
2 Answers
The reasons why a car stalls while driving are: 1. When there is excessive carbon buildup in the throttle, releasing the accelerator during driving may cause the engine to stall; 2. Power supply failure, usually due to a damaged ignition coil, resulting in no high voltage to all spark plugs; 3. Electronic component failure. Solutions for a car stalling while driving include: 1. Ensure to refuel with high-grade gasoline at qualified gas stations; 2. Thoroughly clean the fuel system; 3. Perform regular maintenance. Common car faults include: 1. Excessive fuel consumption; 2. Excessive lubrication oil consumption; 3. Abnormal smoke from the exhaust pipe; 4. Steering deviation; 5. Steering wheel wobble or vibration.
I've been driving for many years, and when it comes to the issue of a car stalling while driving, the most common cause is a problem with the fuel system. For example, the fuel pump may not be working properly, unable to supply fuel steadily, or there may be impurities in the fuel line clogging the injectors, leading to insufficient air-fuel mixture and the engine not getting enough fuel. Another major reason could be an ignition system failure, such as worn-out spark plugs failing to ignite or a faulty ignition coil preventing proper ignition. It might also be an electrical issue, like a failing alternator causing the battery to drain or a malfunction in the control computer. Mechanical problems, such as a dirty air filter blocking the intake, can also cause the engine to stall due to lack of oxygen. Poor maintenance often leads to these issues. If this happens, immediately turn on the hazard lights, pull over safely, and check the problem. Avoid attempting to restart the car to prevent further damage.
