What is the RPM when starting the car?
1 Answers
When starting the car, the RPM is around 1000. The engine's technical condition affects the starting resistance and consequently the RPM. A new engine that hasn't been broken in has higher starting resistance and correspondingly lower starting RPM. After proper break-in and maintenance, when the moving parts achieve optimal fit, the RPM will be slightly higher. In reality, it's difficult for drivers to distinguish the RPM difference between a new car and a well-broken-in one during startup, as the gap is minimal unless precise measurements are taken. From a technical perspective, a car engine's starting performance is evaluated by its starting time - an engine that can start within 5 seconds is considered to have good starting performance.
