Is 1000 RPM Idle Speed Normal for Diesel Vehicles?
1 Answers
Diesel vehicles idling at 1000 RPM is normal. Here is the relevant introduction to diesel vehicle idle speed: 1. The normal idle speed for a vehicle engine is around 900 to 1000 RPM. When the vehicle is in a parked state and the engine is started, the minimum stable operating speed of the engine is called parking idle speed (the process of the engine transitioning from a cold idle state to an idle state where it reaches normal operating temperature is called warm-up or heating); 2. The idle speed can be adjusted by changing the throttle opening size, idle fuel supply, etc. Generally, the optimal idle speed is the lowest RPM at which the engine does not shake within the idle range and has good acceleration performance.
