1 柴油机不能随意使用汽油机油由于柴油机的压缩比是汽油机的2倍多,主要零件受高温高压的冲击要比汽油机大得多,因而两者有些零部件的制作材料有所不同。例如,汽油机主轴瓦与连杆轴瓦可用材质较软、抗腐蚀性好的巴氏合金来制作,而柴油机的轴瓦则必须采用铜铅合金或高锡铝合金等高性能材料来制作,但这些材料的抗腐蚀性能较差,在发动机油中即使有微量酸性物质也会引起严重腐蚀,使轴瓦出现斑点、麻坑,甚至整块金属剥落。为此在柴油机油的炼制过
A diesel engine can not be free to use gasoline engine Since the diesel engine compression ratio is more than 2 times the gasoline engine, the main part of the impact of high temperature and pressure than the gasoline engine is much larger, so some of the two parts of the production of different materials. For example, gasoline engine main bearing and connecting rod bearing bushings can be made of soft and corrosion-resistant babbitt, while diesel engine bearing bushings must be made of high-performance materials such as copper-lead alloy or high-tin-aluminum alloy. However, Poor corrosion resistance, even in the engine oil, a trace of acidic substances can also cause serious corrosion, the bearings appear spots, Ma Hang, or even a whole piece of metal spalling. To do this in diesel oil refining
