What is the Relationship Between Torque and RPM in a Car?

[ODamian]

There is an inverse relationship between engine torque and RPM. Below is a detailed introduction to engine torque: 1. Definition of engine torque: Torque refers to the rotational force output from the crankshaft of an engine. It is a crucial parameter of engine performance, representing the average rotational force output from the crankshaft during operation, commonly known as the engine's "turning power." 2. Relationship between engine torque and RPM: Under constant power conditions, torque is inversely proportional to engine RPM. The faster the RPM, the smaller the torque, and vice versa. This relationship reflects the vehicle's load capacity within a certain range. 3. Functions of torque: (1) Like power, torque is one of the primary indicators of a car engine, influencing performance aspects such as acceleration, climbing ability, and suspension. (2) Torque is an important criterion for evaluating the quality of a car engine. The magnitude of a vehicle's torque is directly proportional to the engine's power.
