过去,为了安装加大活塞环,在修理中一般采用镗缸的办法,将气缸上部未磨损部位车去,再装入加大活塞环。这样做,由于扩大了气缸工作容积,压缩比变小,使用中容易造成起动困难和功率下降等故障,为克服上述缺点,现介绍一种安装加大活塞环的简便方法: 以X195型柴油机为例,气缸套的上端缸口部分,基本上没有磨损,气缸套磨损最厉害的部位是第一道活塞环在上止点附近的位置,沿 In the past, in order to install to increase the piston ring, the boring cylinder is generally used in the repair method, the upper part of the unworn parts of the car to go, and then increase the piston ring. In this way, due to the expansion of the cylinder working volume, the compression ratio becomes smaller, easy to use in the start-up difficulties and power failures and other failures, to overcome the above shortcomings, is now introduced to install a piston ring to increase the convenience: X195 diesel engine For example, the upper part of cylinder liner part of the cylinder, basically no wear and tear, cylinder liner wear the most powerful part of the first piston ring in the position near the top dead center, along
