机油消耗是衡量发动机性能优劣的重要经济性指标之一。按《376Q汽油机性能实验大纲》规定,汽油机机油燃油消耗百分比不得超过0.5％。我厂早期生产的汽油机大多达不到该指标,有的竟高达1.6％,直接影响产品质量,因而如何降低汽油机机油耗,成为急待解决的课题。 1理论依据影响发动机的机油消耗的因素很多,主要原因之一是发动机曲轴箱中的机油经过活 Oil consumption is one of the important economic indicators to measure the merits of engine performance. According to “376Q gasoline engine performance experimental outline” provisions, gasoline engine oil fuel consumption percentage shall not exceed 0.5%. Most of the gasoline engines manufactured by our factory did not reach the targets in the early stage, and some were as high as 1.6%, which directly affected product quality. Therefore, how to reduce gasoline engine fuel consumption has become an urgent issue. 1 Theoretical basis Many factors affect the engine oil consumption, one of the main reasons is the engine crankcase oil through the live
