全日制十年制初中课本物理第一册(人民出版社1980)(以下简称甲书)说:在作功冲程汽油机燃气温度升高到1500℃～1800℃,压强达到30～45kg/cm~2。柴油机在压缩冲程未……燃气温度达到1700℃～2000℃,压强达到60～100kg/cm~2,在柴油机里推动活塞作功的燃气温度和压强比汽油机里的高,燃气作功较多,所以效率较高。初级中学课本物理第二册(人民出版社1983)(以下简称乙书)说:汽油机燃气温度升高到2000℃～2500℃,压强达到30～50kg/cm~2,柴油机压缩冲程冲程
Full-time 10-year junior high school physics textbook first volume (People’s Publishing House 1980) (hereinafter referred to as A book) said: Gasoline gas engine power stroke increased to 1500-1800 ℃, the pressure reached 30 ~ 45kg / cm ~ 2 . Diesel compression stroke is not ... ... gas temperature reaches 1700 ℃ ~ 2000 ℃, the pressure reaches 60 ~ 100kg / cm ~ 2 in the diesel engine to promote the work of the piston gas temperature and pressure higher than the gasoline engine, gas work more, So more efficient. Junior High School Textbook Physics Volume II (People’s Publishing House 1983) (hereinafter referred to as B) said: gasoline engine gas temperature increased to 2000 ℃ ~ 2500 ℃, the pressure reached 30 ~ 50kg / cm ~ 2, diesel compression stroke stroke
