What does engine stall mean?

Motor stall refers to a condition where the motor continues to output torque even when the rotational speed is 0 RPM, which is generally caused by mechanical or human factors. This phenomenon occurs when the motor cannot start or stops rotating due to reasons such as excessive motor load, mechanical failure of the driven equipment, bearing damage, or stator-rotor contact. Conditions: When the motor is running, the rotating magnetic field formed by the stator windings drives the rotor to rotate, while the magnetic field generated by the induced current in the rotor also induces a counter-electromotive force in the stator windings, known as inductive reactance, which prevents an increase in the stator current. Power factor during motor stall: During motor stall, the power factor is extremely low, and the current can reach up to 7 times the rated current. Prolonged stalling can burn out the motor. Therefore, general motor testing includes a stall test. The reason is that it is generally caused by mechanical or human factors. Prolonged motor stalling will eventually burn out the motor.
I think engine stalling simply means the engine suddenly stops and shuts off while the car is running, like when I'm driving and waiting at a red light, the engine inexplicably dies and I have to restart it. Common causes include insufficient fuel supply or a clogged air filter, leading to the air-fuel mixture failing to ignite. I suggest starting with simple checks, such as seeing if the fuel tank is nearly empty, whether the spark plugs are worn out, or if there's carbon buildup in the fuel system that needs cleaning. Developing good habits like regular oil changes and cleaning the throttle body can reduce the risk of stalling. Safety first—if it happens while driving, immediately turn on the hazard lights, pull over safely, and stay calm.
I encountered engine stall when the engine suddenly stopped while running. That time I was making a turn, and the car stalled, which gave me a scare. Possible causes could be a faulty fuel pump not supplying fuel, a weak battery unable to start, or a dirty idle control valve. The solution is simple: shift to neutral and try to restart. Regularly check your car's condition and don't delay maintenance too long, as excessive carbon buildup can easily cause stalling. If stalling occurs frequently, I usually inspect the fuel system and intake tract, and recommend using a high-quality gasoline additive as a preventive measure. Remember to drive safely and don't take it lightly; pull over to handle the situation and ensure safety.
