Is 900 RPM at Idle Normal?

[BeckettAnn]

Idling at 900 RPM is normal. Here are the specific details about car idling: 1. Normal Range: Around 1500 RPM when the engine is cold, and below 1000 RPM when the engine is warm are considered normal ranges. 2. Idling Indicators: Engine idling performance has a significant impact on emissions, fuel consumption, and comfort. Therefore, engine idling performance is an important indicator for evaluating engine performance. 3. Idling Conditions: During idling, the engine is disconnected from the transmission system and the throttle pedal is fully released. The engine only overcomes its own resistance to operate without any external power output. The engine speed during idling is called the idle speed. The idle speed should not be too high or too low. If it is too high, fuel consumption will increase; if it is too low, the engine idle speed will become unstable.
