摘　　要：开发了一种具有上下两层的超多喷孔新型喷油嘴,分析了其结构特点,并进行了相关的发动机性能试验,以及喷雾特性试验,揭示了该超多喷孔新型喷油嘴不但能够同时降低NOx,PM排放,而且能够降低HC,CO排放的机理。A new type super-number-hole injection nozzle with two layer holes was developed, the structural characteristics were analyzed, injection spray and engine performance tests were deployed. Test results show that with this new developed super-number-hole nozzle, the NOx, PM emission and HC, CO emission can be reduced simultaneously.
