当一些驾驶员发现发动机润滑油消耗量增加,并伴有排气管冒黑烟现象时,往往就断言是由于一部分机油通过活塞环的开口间隙或环与槽之间的背隙和侧隙挤入燃烧室参加燃烧而造成的,于是就急于把活塞卸下来,检查活塞环的弹性,清理环槽及油孔,但装复后,上述现象并没有好转。其实产生这种原因有时不仅仅只有这一个原因。大家知道,有些发动机,像解放CA6102型,东风EQ6100型汽油机和奔驰OM402 When some drivers find that the engine oil consumption is increased and accompanied by exhaust black smoke, it is often asserted that a part of the oil passes through the opening gap of the piston ring or the backlash and backlash between the ring and the groove Into the combustion chamber to participate in the combustion caused by, so eager to remove the piston, check the piston ring elasticity, clean the ring groove and oil hole, but after loading complex, the above phenomenon did not improve. In fact, sometimes this is not the only reason for this. We all know that some engines, like liberation CA6102 type, Dongfeng EQ6100 gasoline engine and Mercedes-Benz OM402
