What does x1000r/min mean?

[StJames]

1000r/min represents the engine speed of 1000 revolutions per minute. Here is some information about the engine: 1. r/min, which stands for engine speed, relates to the number of work cycles per unit time or the effective power output of the engine. The effective power of the engine varies with different speeds. 2. The specified effective power and its corresponding speed are referred to as the rated power and rated speed, respectively. The operating condition of the engine at rated power and rated speed is called the rated condition. Rated power is not the maximum power the engine can produce but the maximum usable limit of effective power determined based on the engine's intended use. 3. For the same model of engine, the rated power value may differ depending on its intended use, and the effective torque varies with the engine's operating conditions.
