Does High Temperature Inside the Car in Summer Affect the Vehicle?

[Kimberly]

High temperature inside the car in summer does affect the vehicle. Here are the specific impacts: 1. Affects engine air intake capacity: Leads to a decrease in the engine's air intake coefficient. The higher the temperature, the lower the air density, resulting in reduced actual air intake by the engine; Due to engine overheating, the temperature under the hood increases further, reducing the engine's air intake capacity. 2. High temperatures can cause abnormal engine combustion: High atmospheric temperature increases the temperature of the air-fuel mixture entering the cylinders, raising the temperature throughout the engine's working cycle. Coupled with the lower heat dissipation efficiency of the radiator, the engine becomes overheated. The end-gas mixture in the combustion chamber absorbs more heat, intensifying pre-flame reactions, which increases the likelihood of engine knocking.
