摘要

在世界范围内,采用EGR的柴油发动机的使用日益增加,以减少氮氧化物的排放。采用EGR的发动机可以大大减少氮氧化物,但却会将UHC的排放量提高近40%至50%。我们可以通过UHC的再利用来避免这种影响。本文对采用直喷加压点火发动机插入未燃富碳氢废气的EGR进行了实验研究。将结果与所有EGR水平进行比较。结果表明,该方法可使全民健康覆盖率降低20% ~ 25%。

Effect of Exhaust Gas Recirculation (EGR) on Performance and Emission of a Compression Ignition Engine with Staged Combustion (Insertion of Unburned Hydrocarbon)
The usage of EGR adopted diesel engine increasing day by day world wide to reduce the NOx emissions. The EGR adopted engines can reduce NOx Considerably but it adversely improves the emissions of UHC nearly 40 to 50 %. We can avoid this effect by Reutilizat ion of UHC. In this paper the experimental investigation has been carried out on EGR adopted direct injection co mpression ignition engine with insertion of unburned hydro carbon rich exhaust. The results were presented and compared with all EGR levels. The result were evidenced that can reduce 20 to 25 % of UHC by this method.
