1.关于发动机曲轴室通风管堵塞现象一般的发动机通气管都是装有滤清设备的,但在一般修理中,往往不会去注意这种小问题,不予清洗,结果曲轴室通风不良,气压增加(因为汽缸内爆炸时多多少少有一部份爆炸的气体漏入曲轴室)存在于最后一道曲轴与轴承间的机油,油膜经常被吹出至飞轮壳外而漏掉,如果工作时间长了就发生缺少机油的现象,轴承因此烧毁,又因曲轴室温度过高,活塞及活塞环冷却不够,因温度增高而软化,活塞黏住了活塞环,汽缸也拉出槽来了,马力降低,燃油消耗量增加,故这种问题虽小造成损失却非常巨大的,尤其在风砂较大的地方更应注意。
1 on the engine crankcase ventilation tube blockage General engine exhaust pipe are equipped with filtration equipment, but in the general repair, often do not pay attention to this small problem, not cleaning, the results of bad ventilation crankcase, Pressure increase (because the cylinder explosion more or less part of the explosion of gas leakage into the crank chamber) exists in the last crankcase and bearing oil, oil film is often blown out to the flywheel housing and missed, if the working time is long The phenomenon of lack of oil, the bearing burned, and because the crankcase temperature is too high, the piston and piston ring cooling is not enough, due to temperature increase and softening, the piston stuck the piston ring, the cylinder also pulled out of the slot to lower the horsepower, Fuel consumption increases, so the problem is small, but the loss is very huge, especially in the larger areas of the sand should pay more attention.
