【摘要】 通过对CZ480Q型直喷式柴油机燃烧过程和排放特性的试验研究,系统地分析了燃烧室形状、喷油系统参数、后处 理措施对柴油机燃烧过程和有害排放物的影响,探讨小缸径直喷式柴油机满足欧Ⅱ排放法规的技术对策;最终试验结果 表明,改进措施改善了柴油机的燃烧过程,降低了柴油机有害排放物,排放指标均低于欧Ⅱ排放限值。更多还原

【Abstract】 By investigating the combustion process and emission character of CZ480Q D.I. Diesel, this paper analyzed the influence of combustion chamber shape,parameter of fuel injection system and aftertreatment on combustion process and emission character technical tactics of small D.I. Diesel to Meet EuroⅡEmission Regulation. The contrast test results show that the amendatory measurements can improve combustion process , reduce noxious emission, and all emission values are below EuroⅡEmission limit.更多还原
