• The engine emissions are decreased effectively and can meet the euro i emission standard by making intake vortex ratio and combustible chamber shape better , delaying injection timing , speeding fuel injection spray in combination with other optimization
  通过改善进气涡流比、改进燃烧室形状、延迟供油定时、提高供油速率等改进措施，并进行优化匹配，降低了各项柴油机的排放，使该机型达到欧i排放标准。
• Other content in this paper is the design and investigation of spiral inlet port . the geometries that compose intake port have been repeatedly when intake port scheme was designed . the intake port scheme has been carried out steady - flow test . the experiment data has been analyzed and investigated , then the performance of inlet port has been estimated by the fluid coefficient and the whirl ratio . at last , the spiral inlet port scheme has been selected based on matching relation of the factors of combustion system . in addition , how to " intake port synthesis performance coefficienf ' evaluate engine intake port has been discussed
  本文的另一项内容是螺旋进气道的设计和研究。通过对进气道的几个主要结构参数进行反复修改拟定进气道方案，并对其进行稳流试验，分析和研究试验数据，利用流通系数、涡流比进行进气道性能评估，根据燃烧系统要素的匹配关系，确定了两种螺旋进气道方案。另外，本文探讨了“进气道综合性能系数”对发动机涡流进气道性能的评估能力。
