idle speed

**idle speed**

The term “idle speed” refers to the engine speed (measured in revolutions per minute, or RPM) at which an engine runs when it is not under any load and the accelerator is not pressed. It is the baseline RPM that keeps the engine running smoothly while the vehicle is stationary. Proper idle speed is crucial for engine stability, fuel efficiency, and emissions control. In automotive tuning and maintenance, adjusting the idle speed can help improve drivability and prevent stalling. This tag covers topics related to engine idle settings, troubleshooting idle issues, and optimizing idle performance in cars and other machinery.
