一、怎样正确安装加大的活塞环柴油机修理中,对磨损严重的活塞环,常常根据缸套的磨损情况,换装加大的活塞环(如目前各地农机配件供应部门都有S195柴油机的4种加大尺寸的活塞环供应,即加大0.25、0.5、0.75,1毫米等)。过去,为了安装加大活塞环,在修理中一般采用镗缸的办法,将上部未磨损部位车去,装入加大的活塞环。这样做,由于扩大了气缸工作容积,压缩比变小,实际使用中容易造成起动困难和功率下降等故 First, how to correctly install the increased piston ring Diesel engine repair, the piston ring for serious wear and tear, often based on the wear and tear of cylinder liner, dress up larger piston rings (such as the current parts around the agricultural machinery parts supply S195 diesel 4 Increase the size of the piston ring supply, that increase 0.25,0.5,0.75,1 mm, etc.). In the past, in order to install to increase the piston ring, the boring cylinder is generally used in the repair method, the upper unworn part of the car to go, into the larger piston ring. In doing so, due to the expansion of the cylinder working volume, the compression ratio becomes smaller, the actual use easily lead to difficulties such as starting and power decline so
