【摘要】 在柴油机采用废气再循环(EGR)技术以降低氮氧化物(NOx)排放的情况下,分析了不同供油提前角对发动机排放及油耗的影响情况。根据柴油机EGR控制系统的工作特点和功能,确定了柴油机的最佳供油提前角。根据发动机负荷特性试验结果,验证了在此供油提前角的情况下,EGR控制系统的实际控制效果达到最佳。更多还原

【Abstract】 Influences of different fuel advance angle on engine exhaust emission and fuel consumption are analyzed under the conditions of using EGR technology to reduce NOx emission.In terms of working features and functions of EGR control system in diesel engine,the optimum fuel advance is determined.It is proved by test results of load performance that the actual control effective ness of the EGR control system is optimum under this fuel advance angle.更多还原
