一、有一台装S195柴油机的手扶拖拉机,新车买回后已使用2年多,由于烧机油严重,便更换了活塞环,但烧机油问题仍严重存在。据使用者说,换装新环时肯定没装错,机油也已换用新的。拆下检查,发现缸套与活塞间隙为0.35毫米,未达到磨损极限;用新环放入缸套检查漏光情况,发现漏光严重,不圆度大。临时处理办法:将缸套调转方向重装,并经过一天时间冷磨,情况有所好转。然后空载用小油门低速磨合,三天后故障收敛。二、一台S195型柴油机,换缸套、活塞、活塞环后试车时,发现严重烧机油,用手摇,未曾起动就
First, there is a mounted tractor S195 diesel engine, the new car has been used after buying more than 2 years, due to serious burning oil, they replaced the piston ring, but burning oil is still a serious problem. According to the users, the new ring must not have been installed incorrectly, and the oil has also been changed to new ones. Remove the inspection and found that the cylinder liner and piston clearance of 0.35 mm, did not reach the wear limit; with a new ring into the cylinder to check the light leakage and found that serious light leakage, non-roundness large. Provisional approach: the direction of cylinder liner reloading, and after a day of cold grinding, the situation has improved. Then no load with a small throttle low speed running, fault convergence after three days. Second, a S195 diesel engine, for cylinder liner, piston, piston ring after the test, found that serious burning oil, with a hand crank, never started
