公交车汽油发动机换油周期研究

THE STUDY ON THE OIL DRAIN INTERVALS OF THE GASOLINEENGINE OIL FOR BUS

介绍目前汽车发动机油的换油准则,并从汽油机油的性质出发,对公交车辆发动机油进行取样化验,并对质量变化因素进行分析。试验结果表明,油样的大多数质量指标都在规定的换油周期内,只有粘度超过了国家换油标准。参照国家标准,提出合适的换油周期。

The oil drain standards of the automobile engine oil at present are introduced.According to the quality of the gasoline engine oil,the bus engine oil is tested by taking sample-oil and the oil decay factors are analyzed.The results of bench evaluation indicate that the most quality targets are in the range of national standard for oil drain except viscosity.At last,the proposed oil drain period is pointed out based on the national standard.
