【摘要】 设计了一款应用在柴油机上的电控EGR系统,并进行了不同EGR率对柴油机经济性的影响研究和稳态十三工况下的排放性研究。试验结果表明:采用电控EGR技术后,试验柴油机比油耗在不同工况下有不同程度的升高,尤其在高负荷区域内;NOx排放有着较为明显的下降,微粒有一定程度的升高,HC排放总体上变化不大。更多还原

【Abstract】 We design an electronic control EGR system using in diesel engine,and influence of different EGR rate on engine economy and emission is done.The results shows:using electronically controlled EGR technology,for the test engine,the fuel consumption rises at different degrees,especially in high load areas;NOx emissions have a more significant decline;particles increase to a certain extent;HC emissions have little change.更多还原
