What Causes Engine Stalling?
2 Answers
Engine stalling is largely caused by improper operation by the driver. Common situations that lead to engine stalling include: 1. Insufficient Engine RPM: When starting the car, if the engine RPM is too low and the clutch pedal is released too quickly, the engine will struggle to drive the transmission and rotate the wheels. The sudden resistance on the engine at idle, combined with insufficient torque, can easily cause stalling. 2. Incorrect Gear Selection: When braking, even if the car's speed decreases, staying in a high gear can cause stalling. This happens because the engine cannot maintain power at lower speeds in higher gears. 3. Rolling Back: New drivers often experience rolling back when starting, which can lead to panic and stalling. To prevent this, use the handbrake properly. Before shifting into gear to start, engage the handbrake, partially release the clutch, then disengage the handbrake while applying the throttle. This method ensures a smooth start without rolling back.
Last time my car stalled halfway, it really freaked me out. The cause is often a fuel system issue, like forgetting to refuel with the fuel level too low, or the fuel pump suddenly failing, preventing fuel from reaching the engine. Sometimes it's a problem with the ignition system, such as worn-out spark plugs failing to ignite or faulty ignition coils unable to produce a spark. Electrical system issues can also cause trouble, like insufficient battery power or alternator failure leading to a power outage. Other causes include a clogged air filter restricting airflow or faulty engine sensors giving incorrect readings. To minimize such situations, I make it a habit to check the fuel gauge before driving and regularly visit the maintenance shop to inspect the fuel pump and electrical circuits. In short, these seemingly minor issues can accumulate and leave you stranded on the highway.
