What is the normal idle speed of a car?
1 Answers
The normal idle speed of a car is between 500 to 800 revolutions per minute (RPM). Different models and engines may have varying idle speed values. During idling, the engine operates at a lower speed, resulting in slower air intake and weaker intake vortex to the cylinders, which leads to poor atomization of the air-fuel mixture. This incomplete combustion can cause increased carbon deposits. The car engine is the power-generating device of the vehicle, often referred to as the heart of the car, determining its power, fuel efficiency, stability, and environmental performance. Maintenance methods for car engines include: 1. Regularly changing engine oil and oil filters; 2. Maintaining good crankcase ventilation; 3. Periodically cleaning the crankcase; 4. Regularly cleaning the fuel system; 5. Routine maintenance of the radiator.
