有效降低柴油机机油消耗率的设计改进

Improvement of Design for Effective Reduction of Lube Oil Consumption of Diesel Engine

针对二种不同机型柴油机机油耗率偏高的问题,进行了试验分析,找出其主要因素。对活塞环及活塞进行了改进设计,并对气门导管的装配工艺作了改进,降低了柴油机的机油耗率,取得了令人满意的结果。

A series of tests were carried out on two diesel engines with high oil consumption to find out the root cause. Based on the test and analysis results, design improvement of the piston rings and pistoris of both engines were performed and the assembly process of valve guide was improved.The results showed that the oil consumptions of both engines obviously reduced and reached acceptable levels.
