What is the Impact of Intake Air Temperature on Engine Power?

[OCalvin]

If the intake air temperature is too high, it can cause a decrease in engine power and may also lead to engine knocking. The specific effects of intake air temperature on engine power are as follows: Causes Knocking: If the intake air temperature is too high, it can lead to engine knocking. Knocking is a harmful abnormal combustion phenomenon in the engine. When the piston moves upward to compress the combustible mixture, the pressure and temperature of the mixture will rise. If the combustible mixture ignites before the spark plug fires, this is known as knocking. Causes Decrease in Engine Power: If the intake air temperature is too high, the combustion of the combustible mixture will push the piston downward, resulting in reduced engine power and increased fuel consumption.
