4115柴油机使用中,有的通气孔不断往外喷溅出一股股油烟气雾,使得柴油机外表脏污,为此有的拖拉机手在通气管孔上又接一根长橡胶管,把喷溅的油烟气雾导向地面。我们认为这种做法是不恰当的,因为接装橡皮管会影响曲轴箱正常通风,再者如果通气孔往外不断喷溅油雾,说明曲轴箱内压力过大。这时如果打开曲轴箱加油口盖,即可发现从加油管口也往外不断喷溅出油烟气雾。正常状态的柴油机,工作中不应有上述现象。但
4115 Diesel engine, some vents continue to spit out a share of fumes mist, making the appearance of diesel engine dirty, so some tractor hand in the vent hole and then take a long rubber tube, the splash Fumes aerosol directed to the ground. We think this approach is not appropriate because the attached rubber tube will affect the normal ventilation of the crankcase, and if the air vent continuously splashes the oil mist, it indicates that the pressure inside the crankcase is too high. At this time if you open the crankcase fuel filler cap, you can find out from the fuel nozzle also continuously spit out fume aerosol. The normal state of diesel engine, the work should not have the above phenomenon. but
