我国自行设计的95系列柴油机是目前农村中广泛使用的机型之一,由于各方面的原因,产生机油消耗高的问题。有的在使用100～200小时后,机油消耗率高达10克/马力小时。为了寻求减少机油消耗量的途径,我们在两台 S195上进行了机油消耗的试验研究(出厂时机油消耗率在3～4克/马力小时),现将影响机油消耗的主要因素和试验结果分析于下:机油消耗的途径是,通过活塞环与缸套之间的间隙或闭式呼吸器进入燃烧室烧掉;通过气门和导管之间的间隙进入燃烧室;通过呼吸器(开式)、加油口或密封面向外渗漏。此外高温燃气下窜至曲轴箱,烧
China’s own design of the 95 series diesel engine is currently one of the widely used models in rural areas, due to various reasons, resulting in high oil consumption problems. Some use 100 to 200 hours, the oil consumption rate of up to 10 grams / horsepower hours. In an effort to find ways to reduce oil consumption, we conducted experimental studies on oil consumption at two S195s (3 to 4 g / h hrs at the factory) and will now analyze the major factors and test results that affect oil consumption In the next: The oil consumption is through the gap between the piston ring and cylinder liner or closed breathing apparatus into the combustion chamber burned; through the gap between the valve and the catheter into the combustion chamber; through the respirator (open) Leaking oil or sealing surface outward. In addition, the high-temperature gas ran down to the crankcase, burning
