1995年我县对195柴油机进行了增容改造,实践证明,它具有方便、省钱、省油、增加功率等优点,值得推广和应用。下面就装配和优化调整中应注意的几个问题介绍如下: 1.部件的选配 (1)活塞顶部凹坑深度应在2.5～3.0毫米之间; (2)活塞销孔轴心线至活塞顶部距离为60毫米; (3)活塞顶平面凸出缸体平面控制在0.5～0.79毫米以内; In 1995, our county carried out the compatibilization of 195 diesel engine. Practice has proved that it has the advantages of convenience, saving money, fuel saving and increasing power, which is worth popularizing and applying. Below the assembly and optimization of the adjustment should pay attention to several problems are described below: 1. Parts Selection (1) the depth of the pit on the piston should be between 2.5 to 3.0 mm; (2) piston pin hole axis to the piston The top of the distance of 60 mm; (3) the top plane of the piston protruding plane control within 0.5 ~ 0.79 mm;
