What is the normal RPM for a car engine when it is just started?

[BenjaminFitz]

When starting the car, the engine RPM of 1200 to 1500 is normal. More knowledge about car starting is as follows: 1. After the car starts, there is a high idle speed process, especially in winter, which is more obvious. This is a phenomenon controlled by the on-board computer (for vehicles with electronic throttle control systems). When the engine reaches a certain temperature, the idle speed will return to normal. This helps accelerate the engine temperature to the normal working condition when starting a cold car. 2. There may be slight abnormal noises when starting the car engine. If the noises disappear after a few minutes of warming up, this does not affect the vehicle's driving. Because after the vehicle has been parked overnight, the engine oil in various components has flowed back to the oil pan, so it is best to warm up the car for a few minutes in the morning. One reason is to allow the oil to be evenly supplied to all components, and the other is to raise the engine temperature for better performance.
