引起S195柴油机窜机油的原因很多,我们发现由气门导管引起的窜机油现象较为普遍。原因是: (1)气门导管孔与气门杆配合间隙不当; (2)气缸盖罩壳内机油喷射方向不妥; (3)气缸盖罩壳内机油喷射压力太高,从而引起雾化机油过量。气门导管孔与气门杆配合间隙基本上是能控制在要求范围内的;机油喷射方向在目前生产条件下也已达到较为理想的状态;唯有机油喷射压力太高,导致雾化机油过多,还一直没有引起人们的重视。事实上它正是引起机油下窜的重要因素。为此,我们在分析总结经验的基础上,采取了以下措施:在机油指示阀小活塞上加工一
Cause S195 diesel engine channeling oil for many reasons, we found that caused by the valve guide channeling oil phenomenon is more common. The reason is: (1) the valve guide hole and valve stem with improper clearance; (2) improper jet direction of the cylinder head cover oil; (3) the cylinder head cover oil injection pressure is too high, resulting in excessive atomizing oil . Valve guide hole and valve stem with the gap is basically able to control the required range; oil jet direction in the current production conditions have also reached the ideal state; only the jet pressure is too high, resulting in excessive atomizing oil, Has not been caused by people’s attention. In fact it is precisely the cause of the oil channeling an important factor. To this end, we analyze the lessons learned based on the following measures: the oil valve on the small piston processing a
