Is It Normal for the Engine to Remain Hot Several Hours After the Car Is Turned Off?

It is normal for the engine to remain hot several hours after the car is turned off. Below is a brief introduction about the engine: 1. Basic Information: 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 of the UK (Scotland) in 1816, which was later improved by Watt into the steam engine. 2. Applicable Devices: Engines can be used as power generation devices or refer to the entire machine including the power unit (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.
It's quite common for my car's engine hood to still feel hot to the touch even after being turned off for four or five hours. After long-distance driving or during hot summer days, a large chunk of metal like the engine dissipates heat slowly and might take half a day to cool down. As long as there's no burning smell or smoke, it's usually fine. I've also noticed that parking in the shade or opening the windows for ventilation can help speed up the cooling process. Next time after a highway drive, don't rush to touch the engine—just wait it out.
