What Does Stall Mean?
1 Answers
Stall refers to the phenomenon where the output speed of the torque converter is zero while the engine is running during normal driving, meaning the pump wheel rotates while the turbine remains stationary. Traditional automatic transmission vehicles often experience stalling, which can also lead to gear shift delays. The faster the automatic transmission shifts, the higher the efficiency and the better the fuel economy. Car stalling occurs when the engine loses control, including stalling, unresponsive throttle, or runaway acceleration. There are many common causes of stalling, but they mainly involve failures in fuel, electrical, cooling, or mechanical systems, such as a stuck throttle cable, jammed throttle motor, poor contact in the throttle sensor, open circuits, excessive engine temperature, or lack of gasoline, engine oil, or coolant.
