What is the general idle speed of a car?
1 Answers
The general idle speed of a car is between 550 and 800 revolutions per minute. When the engine is running, if the accelerator pedal is completely released, the engine enters the idle state. During idle speed adjustment, the RPM should not fluctuate abruptly, as this can cause premature wear to the engine. It is recommended to have the idle speed adjusted at an automotive repair facility. Idle speed can be categorized into normal idle and driving idle. Engine maintenance methods include: 1. Using high-quality engine oil; 2. Using qualified coolant; 3. Regularly cleaning the radiator scale; 4. Periodically removing carbon deposits from the car; 5. Timely replacement of the car's three filters (air, oil, and fuel filters); 6. Maintaining a reasonable engine speed.
