中文摘要：
为找到全面降低柴油机排放的途径，研究了加装氧化催化转化器对柴油／甲醇组合燃烧（DMCC）发动机排放特性的影响，比较了不同工作模式下各污染物的排放量。试验结果表明，DMCC模式下NOx和碳烟排放下降幅度较大，但HC和CO排放增加较多，微粒比排放量也有所增加。经过氧化催化后，HC和CO得到了较大程度的降低，微粒（PM）经氧化后比原机也有所下降。DMCC经采用催化转化器后，废气质量得到改善，实现了同时降低柴油机的NOx和PM的目的。
英文摘要：
This paper presents a new combustion model DieseL/Methanol Compound Combustion （DMCC）, in which methanol is injected into the manifold and ignited by in-cylinder injected diesel fuel. The results showed that DMCC could remarkably decrease NOx and smoke emissions while increasing HC, CO and PM emissions. With a catalytic converter, HC, CO and NOx could dramatically be decreased, and PM also gave a lower value compared with that of diesel engine. The testing results showed that DMCC combining with oxidation catalyst converter could reduce engine NOx and PM emissions simultaneously.
