What Does the Torque of a Small Car Represent?

[VanCamilla]

The torque of a car refers to the moment of force output from the crankshaft end of the engine. Under a fixed power condition, it has an inverse relationship with the engine speed: the faster the speed, the smaller the torque, and vice versa. This reflects the car's load capacity within a certain range. Torque is one of the primary indicators of an engine, influencing car performance, including acceleration, climbing ability, and suspension. Below is an introduction to small car torque: 1. The precise definition of torque. The piston's reciprocating motion in the cylinder does a certain amount of work per cycle, with its international standard unit being the joule (J). The work done per unit distance is torque. Torque is an important standard for measuring the quality of a car engine, and the torque of a car is directly proportional to the engine's power. 2. The representation method of engine torque. It is expressed in newton-meters (N·m). Similar to power, the maximum output torque of an engine is usually indicated along with the corresponding rotational speed in revolutions per minute (r/min). The maximum torque typically occurs in the mid-to-low speed range of the engine and tends to decrease as the speed increases.
