【摘要】 废气再循环(EGR)率的合理控制对NOx的净化效果和整机排放极其重要。为此,分析比较了各种EGR率的评价方法,提出了新的EGR率评价指标比废气再循环率ηEGR,同时阐明了EGR率闭环控制的必要性及其控制方法。更多还原

【Abstract】 It is important to control the Exhaust Gas Recirculation (EGR) rate of Internal Combustion Engine to reduce NOX emission and other emissions. It analyses the different kind of evaluation methods of EGR rate and raises one new method of Specific EGR rate ηEGR. It also states the necessity and control methods of closed-loop control of EGR rate.更多还原
