Why is the engine still very hot several hours after the car is turned off?

[VonRiley]

The engine remaining very hot several hours after the car is turned off is a normal phenomenon. Here is a brief introduction about the engine: 1. Basic information: An engine (Engine) is a machine that can convert other forms of energy into mechanical energy. The first external combustion engine was invented by R. Stirling in the UK (Scotland) in 1816, which was later improved by Watt into a steam engine. 2. Applicable devices: Engines can be used as power generation devices or refer to the entire machine including the power device (e.g., gasoline engines, aircraft engines). Their types include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), gas turbines (used in racing cars), electric motors, etc.
