气缸余隙是柴油机的主要调整参数之一,此值正确与否将直接影响压缩比。正确的选择余气间隙垫片厚度以得到满意的余气间隙值是柴油机在组装、检修过程中必不可少的一道工序。选择垫片的方法,普遍采用的是“压铅法” (图1),其操作方法是:先将一定厚度的垫子(工艺垫)放在缸套凸台上,同时在活 Cylinder clearance is one of the main parameters of diesel engine adjustment, this value is correct or not will directly affect the compression ratio. Correct choice of gas gap gasket thickness in order to obtain a satisfactory residual gas gap value is the assembly and maintenance of diesel engine is an essential part of the process. Select the gasket method, commonly used is the “lead-pressure method” (Figure 1), the method of operation is: first a certain thickness of the mat (craft pad) on the cylinder boss, while living
