What does RPM mean?
1 Answers
RPM stands for revolutions per minute, which indicates the number of rotations the engine makes in one minute. The engine's RPM is directly related to the number of work cycles per unit time or the effective power output of the engine, meaning the effective power varies with different RPM levels. Here is some relevant information about car RPM: 1. Definition of rated condition: When specifying the effective power of an engine, the corresponding RPM must also be indicated. The operating condition of an engine at its rated power and rated RPM is called the rated condition. 2. Adjust to the economical RPM range: Most car engines have an economical RPM range where the engine operates more fuel-efficiently. When driving, the gear must match the engine's RPM and driving speed.
