摘要: 为降低柴油机的排放,近年来,研究加入氢气对重型柴油机排放所产生的影响逐步引起了研究者的关注。在Cummins ISM370柴油机中添加不同比例氢气(最高氢气占进气管氢气空气容积比达7%)与柴油组成混合燃料,进行CO、CO2、HC等排放特性研究。研究结果表明:在各种负荷下,氢气和柴油的混合燃料有助于降低CO、CO2比排放,但总体对THC影响不大;随掺氢量增加,CO、CO2和THC的各自比排放随着负荷的变化规律不尽相同;应该根据负荷选择恰当的加氢比例,最大限度发挥加氢对减少排放的积极作用。

Abstract: In order to reduce the emissions of diesel engine, the investigation into the effect of H2 addition on the emissions of heavy-duty diesel engines is attracting attention from researchers in recent years. The effects of H2 addition at different proportions (the highest volume proportion of hydrogen is 7% of hydrogen air mixture in inlet pipe) on the emissions of CO, CO2 and HC in Cummins ISM370 diesel engine are researched. Research shows that the addition of hydrogen can benefit the reduction in the emissions of CO, CO2 and THC in various loads, and has little effect on the emissions of THC. Moreover, with the increase in amount of hydrogen, the emission characteristics of CO, CO2 and THC varies with the change of load. The amount of hydrogen added should be appropriate to load operation to reduce the emission in maximum extent.
