Why Does the Car Hood Feel Hot to the Touch?

[HaydenRose]

The hood of the car feeling hot is a normal phenomenon. When the engine is running, the external temperature can reach above 90℃, and the exhaust pipe temperature can exceed 500℃. Additionally, the insulation layer and undercover on the hood block the dissipation of heat, so the car hood remains hot even long after the engine is turned off. Below is additional information: 1. Automatic Cooling Function: Some vehicles are equipped with an automatic cooling function, meaning that after parking, if the engine temperature is too high, it will automatically activate the fan to continuously cool the engine. The fan will automatically stop once the engine temperature drops to an appropriate level. 2. Hood Material: The hood is made of rubber foam and aluminum foil materials, which not only reduce engine noise but also isolate the heat generated during engine operation, effectively protecting the paint on the hood's surface and preventing aging.
