What is the normal engine RPM when starting the car?

[Marty]

Different vehicle models have varying cold start RPM values due to differences in engines. The cold start RPM for engines typically ranges between 1,000 and 1,400 RPM. Generally, the idle speed ranges from 500 to 850 RPM, while the instantaneous idle speed during a cold start is around 1,500 to 2,000 RPM. Once the engine coolant temperature returns to 90 degrees, the idle speed will stabilize within the specified range. Additional information about car idling is as follows: 1. There is a high idle process after a cold start, which is more noticeable in winter. This phenomenon is controlled by the vehicle's onboard computer (in vehicles with electronic throttle control systems). 2. When the engine reaches a certain temperature, the idle speed will return to normal. This helps accelerate the engine temperature to normal operating conditions during a cold start.
