What is the engine speed when it first starts?

Due to differences in engines, the cold start speed varies. The cold start speed of an engine typically ranges between 1000-1400 RPM. Below is some information about car engine speed: 1. The general idle speed is between 500 to 850 RPM, while the instantaneous idle speed during a cold start ranges from 1500 to 2000 RPM. 2. There is a high idle speed 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). Once the engine reaches a certain temperature, the idle speed returns to normal.
