甘南柴油机厂生产的 L195型柴油机,燃油消耗率偏高,约187克/马力小时。为降低燃油消耗率,甘南柴油机厂与佳木斯工学院协作攻关,已于1983年5月完成,使燃油消耗率降低4～8克/马力小时。现将采取的措施介绍如下:1.消除内应力减小机体与缸盖的变形该厂以前生产的机体和缸盖铸件不经回火和时效处理,直接进行机械加工,因此变形严重,出现漏气、烧缸垫、镶块松动等现象。过去该厂采用加大缸套上端面凸出机体 The L195 diesel engine produced by Gannan Diesel Engine Plant has a high fuel consumption rate of about 187 g / hh. To reduce fuel consumption, Gannan Diesel Engine Works collaborated with Jiamusi Institute of Technology in May 1983 to reduce the fuel consumption by 4 to 8 grams / horsepower. The measures to be taken are as follows: 1. To eliminate the internal stress to reduce the deformation of the body and the cylinder head The factory previously produced body and cylinder head castings without tempering and aging treatment, direct mechanical processing, the deformation is serious, there is leakage Gas, burning cylinder pad, loose pieces and other phenomena. The factory in the past to increase the bulge on the surface protruding body
