How to Improve Thermal Efficiency?

[VanMaci]

Improving thermal efficiency can be achieved through the following methods: 1. Reducing friction losses; 2. Enhancing the internal lubrication performance of the engine; 3. Improving the combustion conditions of the engine. Automotive thermal efficiency refers to the ratio between the mechanical work output by the engine and the chemical energy produced by burning fuel, which evaluates how much heat is converted into effective work. When the engine operates, only a portion of the thermal energy contained in the fuel is transformed into propulsion work, while the rest is lost in the form of heat or kinetic energy. The thermal efficiency of most automotive engines ranges between 30% to 38%, and the engine's thermal efficiency is primarily determined by its fuel injection system.
