What is the engine speed when the car is idling?

[DelElliana]

The normal engine speed when a car is idling should be around 850 RPM. If the car is cold, it is best not to exceed 1200 RPM. Small-displacement cars usually have an idle speed close to 700 RPM, while larger-displacement cars may approach 1000 RPM. Below is an extended introduction to car idling: 1. Car idling refers to a working condition. When the engine is running without load, it is called idling, meaning the car is in neutral gear. The engine speed during idling is called the idle speed. The idle speed can be adjusted by modifying the throttle opening size, among other methods. Idling means the engine is "running without doing work." 2. When the engine is running, if the accelerator pedal is fully released, the engine enters the idling state. When adjusting the idle speed, the RPM should not fluctuate abruptly, as this can cause premature wear to the engine. It is best to have it adjusted at an automotive repair facility. 3. When the vehicle is parked and the engine is started, the minimum stable engine speed is called parking idle speed (the process of the engine transitioning from cold idle to normal operating temperature idle is called warming up or heating the engine).
