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。
