Abstract For the serious phenomenon of the traditional nozzle spray run into a wall and the spray interference of general porous nozzle under high injection pressure, this paper designed a staggered arranged porous nozzle with upper and lower layers, clarified the structure and theoretical basis of the doublestaggered arranged porous nozzle, established the spray and combustion models to study the spray characteristics of the doublestaggered arranged porous nozzle and the influence of its structural parameters on combustion and emissions performance of the common rail diesel engine. The spray simulation shows that the doublestaggered arranged porous nozzle has a shorter injection distance and better spatial distribution of fuel properties compared with conventional nozzle. The influence of structural parameters of doublestaggered arranged porous nozzle on common rail diesel engine combustion and emission performance shows that the upper nozzle spray angle using a large one or under nozzle using a small diameter, can make the diesel combustion and emissions performance further improved.
