一、前言175F-1.型柴油机由于各方面的原因,在生产和使用中普遍反映机油消耗率偏高,并有因烧机油而引起的烧瓦和飞车等现象.一九八○年试制的第三轮样机共10台,在完成各项试验后,经12小时标定工况考核,机油消耗率达到设计要求的(设计指标≤5g/(PS·h)只有5台,合格率仅50%.一九八一年出厂的小批产品,机油消耗率虽有所下降,但仍不稳定,少数产品机油消耗率高达8～10g/(PS·h).
I. INTRODUCTION Due to various reasons, 175F-1 diesel engine generally reflects the high consumption rate of oil in production and use, as well as the phenomenon of burning tile and speeding car caused by burning oil. The third round of prototype a total of 10, after the completion of the test, after 12 hours of calibration conditions assessment, oil consumption rate to meet the design requirements (design index ≤ 5g / (PS · h) only 5, the passing rate of only 50% In 1981, a small batch of products shipped at the factory showed a slight decrease in oil consumption but remained unstable. The consumption rate of some products was as high as 8-10 g / (PS · h).
