中文摘要：

在增压中冷发动机上采用柴油/甲醇组合燃烧(DMCC)方式进行排放特性的试验研究。结果表明:采用DMCC方式,增压中冷发动机的NOx和碳烟及微粒排放同时较大幅度下降,但HC和CO排放增加较多。加装氧化催化转化器后,HC和CO得到了大幅度的降低,微粒(PM)也进一步减少。按照国Ⅲ规定的检测方法,该机的NOx由6.49 g/(kW.h)降到4.33 g/(kW.h),微粒由0.11 g/(kW.h)降到0.05 g/(kW.h),HC由0.49 g/(kW.h)降到0.04 g/(kW.h),CO基本保持不变,使发动机仍在采用原有的泵管嘴燃油喷射系统的情况下,排放品质由国Ⅱ提升至国Ⅲ水平,测试结果显示了该方法具有进一步减少有害排放的潜力,而其燃料经济性与原机相当。

英文摘要：

Experimental research on emission characteristics of diesel/methanol compound combustion(DMCC) diesel engine with turbocharged inter-cooled was performed to reduce the NOx and PM emission simultaneously.The results show that NOx and PM are reduced remarkably,while the unburned HC and CO are increased.HC and CO can be reduced by a catalytic converter.According to the national phase Ⅲ specified test method,the NOx in the DMCC diesel engine is reduced from 6.49 g/(kW·h) of the baseline engine to 4.33 g/(kW·h),...
