Emissions Characteristics of Diesel Engines for Inland Waterway Vessels in China

  • 摘要: 利用由SEMTECH-DS和ELPI组成的PEMS(车载排放测试系统),对京杭运河江苏段具有代表性的12艘内河船舶进行实际排放测试,分析不同工况下CO、HC、NOx和PM的排放. 结果表明:巡航工况下CO、HC和PM排放速率分别为0.093、0.019、0.018g/s,低于进、出港工况;而NOx排放速率为0.347g/s,分别为出港和进港工况的1.66和2.90倍;不同工况外排NO占NOx比例不同,其中巡航工况中外排NO所占比例最大(达到96.7%),而出港和进港工况则分别为93.6%和93.1%. 随着负荷增加,船舶 CO、HC、NO和PM的排放浓度增大,高负荷下CO、HC、NOx、PM的排放浓度比低负荷分别增高89.23%、29.51%、44.72%和229.49%. 由颗粒物的粒径分布可知,3种工况下颗粒物数浓度的粒径分布呈双峰分布,分别对应核模态和积聚模态,粒径<120nm的颗粒物数浓度占总浓度的99.84%以上,PM2.5数浓度占PM10比例均超过99.9%.
