What RPM is needed for a new car to start?
1 Answers
When starting a new car, the RPM is between 250-350 rpm. After starting, the idle RPM varies depending on the temperature. There are mainly two scenarios, which are: 1. In cold winters with low temperatures, the car's RPM is around 1100 rpm. 2. In hot summers with high temperatures, the car's RPM is around 650 rpm. Additional information: The car's tachometer is divided into several zones. The white scale indicates the safe RPM range, while the red scale marks the dangerous RPM range. Some models also have a green zone, which indicates the most fuel-efficient RPM range for the engine. Generally, as long as the RPM does not enter the dangerous range, it is considered normal. However, it's important to ensure that the RPM matches the current gear. Otherwise, driving at low gear with high RPM or high gear with low RPM can cause unnecessary damage to the vehicle.
