摘　　要：在柴油机稳态工况下,通过试验测定了不同空燃比时,NOx、HC、CO、烟度和油耗的变化。通过对测试数据的分析,确定了最佳空燃比MAP。为基于UEGO的柴油机EGR系统的闭环控制奠定了基础。Experiments are carried out under several operating conditions. For each operating condition, NOx, CO and HC emissions, smoke opacity, and BSFC are measured corresponding to different air-fuel ratio. The best air-fuel ratio (A/F) map is established by analyzing the tested data. The foundation for closed loop control of Diesel EGR based on UEGO sensor is provided.
