摘　　要：对多组柴油机油城市公交车实车使用试验样品粘度的变化及引起这种变化的原因,特别是燃油的稀释进行了叙述,同时分析了由于发动机在用油粘度降低增加的磨损。通过实车使用试验数据的说明及本文的分析,提出了在选用城市公交车发动机润滑油粘度时应注意的问题。The viscosity change of oil samples in field tests of diesel engine oil for urban bus is described and the reason especially diesel engine oil diluted by diesel oil is presented also. At the same time, the wear augmentation of engine caused by oil viscosity degradation is analyzed. Finally, some proposals on selecting viscosity of diesel engine oil for urban bus are put forward.
