Why does the car keep making noise after being turned off?

[Julianna]

The reason the car keeps making noise after being turned off is due to the engine cooling fan. After shutting off the engine, the electric fan continues to operate for a period to dissipate heat from the engine coolant circulation system. Below is an introduction to engines: 1. Introduction: An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy. The first external combustion engine was invented by R. Stirling in the UK (Scotland) in 1816 and later improved by Watt into a steam engine. 2. Applicability: Engines can be used as power generation devices or refer to the entire machine including the power unit (e.g., gasoline engines, aircraft engines). 3. Types: Types include internal combustion engines (e.g., gasoline engines), external combustion engines (e.g., Stirling engines, steam engines), gas turbines (used in racing cars), electric motors, etc.
