What Does Automotive Torque Refer To?
1 Answers
Automotive torque refers to the rotational force output from the crankshaft of an engine. Under constant power conditions, it has an inverse relationship with engine speed – the faster the speed, the smaller the torque, and vice versa. It reflects the vehicle's load-bearing capacity within a certain range. External torque is called torsional moment or external couple moment, while internal torque is referred to as internal couple moment or torque. The magnitude of automotive torque plays a decisive role in the vehicle's speed and climbing ability. The greater the torque, the more power the engine outputs, the faster the crankshaft speed changes, and the better the vehicle's climbing ability, starting speed, and acceleration performance. Its unit is Newton-meter (Nm).
