torque is one kind of special torque that causes an object to rotate. Engine torque refers to the exportation torque of the engine from the crankshaft end. Under the condition of fixed power, it is inversely proportional to the engine speed, the faster the speed, the smaller the torque, and the larger the vice versa, which reflects the load capacity of the car in a certain range. The external torque is called the torque or the external torque, and the internal torque is called the internal torque.

torque: T = F*D

F = force

D = torque length
