Engine RPM, or revolutions per minute, measures how fast the engine’s crankshaft is rotating. It indicates the engine’s current speed and is a critical parameter for monitoring and controlling engine performance. Maintaining the right RPM range ensures efficient operation and optimal power output, while excessive RPM can lead to engine stress and damage.
