| Abstract:Proper thermal insulation engine is an engine applying heat isolating technique to the main parts of combustion chamber.When the engine is operating,the heat transferred from the surface of combustion chamber to cooling water is reduced,thus the dimension of the whole engine cooling system could be reduced. The thermal insulation technology and influence of proper thermal insulation engine on engine performance are introduced and analyzed, and the development trend of proper thermal insulation engine is discussed. |
