摘要
在冷起动、自由加速工况及3种转速50%负荷工况下,采用自行设计的袋式微粒采集系统对柴油机微粒进行采集,并用归一化法作为定量方法对色谱进行了定量分析。试验表明,冷起动、自由加速工况约有25%的有机可溶成分来自润滑油,稳态工况约有40%～60%的有机可溶成分来自润滑油。
Particles of the diesel engine are collect ed with the self-designed bag-type particle collection system un-der the two o perating modes of cold starting and free accelerating and at three speeds under 50%loads.Quantitative anal-ysis of chromatogram is done with the normalizat ion method.It is shown by tests that about 25%of organic soluble compo-siti on comes from lubrication oil under modes of cold starting and free accelerating ,and about 40%～60%of organic solu-ble composition comes from lubricatio n oil.
