Why is the engine hood hot on both sides but not in the middle?

It can be divided into normal and abnormal situations: 1. Normal situation: (1) It is normal for the engine hood to become hot. Because the heat dissipated by the engine will accumulate on the hood. At this time, you can also check the water temperature gauge. If the water temperature is around 90 degrees, it is normal. (2) The water temperature indicator light is used to indicate the temperature of the coolant in the engine. Some will display different effects in colors: blue indicates the water temperature is too low, red indicates the water temperature is too high, and no light indicates normal. 2. Abnormal situation: The temperature of the engine starts to rise rapidly just a few seconds after starting, because the engine needs to reach a certain temperature to perform better. After the car starts, the piston moves very quickly, and the mixed gas of gasoline and air burning in the cylinder rapidly combusts and expands to drive the piston movement, which of course generates a huge amount of heat. Therefore, to ensure that the heat does not rise too quickly and damage the engine, heat dissipation is necessary. However, the engine compartment space is limited. When the car is moving, the wind generated by speed and the fan blow the heat from the radiator into the engine hood, and since the hood is made of metal, it heats up relatively quickly.
