What are the effects of excessively high engine intake air temperature?
2 Answers
The effect of excessively high engine intake air temperature is to reduce the service life of the automobile engine. The following is a detailed introduction about automobile engines: 1. Overview: The automobile engine is the device that provides power for the automobile, determining its power performance, fuel economy, stability, and environmental friendliness. According to different power sources, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid power, etc. 2. Others: Common gasoline engines and diesel engines belong to reciprocating piston internal combustion engines, which can convert the chemical energy of fuel into the mechanical energy of piston movement and output power externally. Gasoline engines have high speed, small mass, low noise, easy starting, and low manufacturing cost. Diesel engines have large compression ratio, high thermal efficiency, and better economic performance and emission performance than gasoline engines.
I once experienced a situation while driving on the highway in summer where the engine intake temperature soared, and the car felt noticeably sluggish during acceleration, with power lagging behind, making overtaking particularly difficult. Later, I learned that hot air has lower density and reduced oxygen content, leading to incomplete combustion and a direct drop in engine power output, along with a significant increase in fuel consumption. Prolonged exposure to such conditions can cause excessively high temperatures in the cylinders, which may trigger knocking—that kind of rattling noise—and cause considerable wear to the pistons and valves. I make it a habit to regularly clean the air filter and check the cooling fan to prevent such minor issues. If your car is driving in hot weather, it's best to stop and let it cool down; don't push it too hard to avoid damaging core components.
