在修理中 ,我们遇到一台１９５型发动机 ,机手说开始时常出现发动机自动熄火 ,经过清洗空滤器、柴油滤清器和排气后又能启动 ,启动后几分钟就自动熄火 ,近来这种现象更为严重。我们根据机手的反映 ,认为这种自动熄火 ,既不是烧瓦抱轴和活塞卡死（熄火后曲轴仍能转动自如） ,也 In the repair, we encountered a 195 engine, the engine often said the engine starts to turn off automatically, after cleaning the air filter, diesel filter and exhaust can start, a few minutes after the start automatically turn off, this The phenomenon is even more serious. According to the response of the driver, we think that this automatic flameout is neither the burning of the holding axle and the piston stuck (the crankshaft can still turn freely after the flameout)
