摘 要: | 在碱性空气介质参与农用车发动机缸内燃烧的条件下,通过改变碱性空气介质浓度,分别测试农用车发动机一氧化碳(CO)、碳氢化合物(HC)、氮氧化物(NOx)、二氧化碳(CO2)等污染物的排放量值变化规律。试验研究发现,碱性空气介质参与农用车缸内燃烧对发动机排放有一定的影响,发动机气缸内燃烧更趋近于完全燃烧,其动力性及燃油经济性都将有一定程度地提升。其中一氧化碳(CO)和氮氧化物(NOx)的排放量有所减少,碳氢化合物(HC)排放有少量增加。

Abstract: | Under the conditions of alkaline air medium participating combustion of farm vehicle engine, through changing the concentration of alkaline air medium concentration, the emission variation law of CO, HC, NOX, CO2 was measured. The results showed that alkaline air medium participating combustion of farm vehicle engine has a certain influence to emission, power porformanee and fuel economy increase. Among which, CO and NOX emission reduced, while HC emission increased a little. |
