在单缸柴油机上安装负压阀(亦称单向阀),利用曲轴室的容积变化,使之形成负压,从面避免了机油窜入燃烧室和渗漏损失。根据这个道理,我自己也制作了一个负压阀,如图1,2所示。制作方法是:1.先把X195和S195型柴油机的齿轮室盖与进气管相通的管接头螺栓拧下来,在该螺孔的上方约10毫米处钻 In a single cylinder diesel engine installed negative pressure valve (also known as one-way valve), the use of changes in the volume of the crank chamber to make it a negative pressure from the surface to avoid the oil fleeing into the combustion chamber and leakage losses. Based on this principle, I also made a negative pressure valve, as shown in Figure 1,2. Production methods are: 1. First X195 and S195 type diesel engine gear chamber cover and pipe connected to the inlet pipe bolts screwed down, about 10 mm above the screw hole at the drill
