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。
Through the experimental research on the combustion process and emission characteristics of CZ480Q direct injection diesel engine, the effects of combustion chamber shape, injection system parameters and post-treatment measures on the combustion process and harmful emissions of diesel engine were systematically analyzed. The effects of small bore direct injection The diesel engine meets the technical regulation of Euro Ⅱ emission regulation. The final test results show that the improvement measures improve the combustion process of diesel engine, reduce the harmful emissions of diesel engine, and the emission targets are lower than the Euro Ⅱ emission limit.
