How is Torque Generated?

[DelKingston]

Torque is generated by the explosive force produced in the engine cylinders. This explosive force drives the cylinders to perform work, and the downward motion creates a force. The force is transmitted through the connecting rod to the crankshaft, causing the crankshaft to rotate, thus forming what is commonly referred to as torque. Torque refers to the moment output from the crankshaft end of the engine. Under fixed power conditions, it has an inverse relationship with engine speed—the faster the speed, the smaller the torque, and vice versa. The unit of torque is Newton-meters (Nm). Torque reflects a vehicle's load capacity within a certain range. Comparing cars with the same type of engine, a higher torque output results in greater carrying capacity, better acceleration performance, stronger climbing ability, fewer gear shifts, and relatively reduced wear on the vehicle.
