摘要
详细讨论了内燃机气道流动特性的定义、测量技术和评价方法。分析了Ricardo方法与AVL,FEV方法所定义的涡流比和流量系数间的关系,对叶片风速仪和涡流动量计测量所得涡流比进行了比较,并介绍了评判气道综合性能优劣的方法。
The definition, measurement technique and evaluation methods to flowing performance of intake port in internal combustion engine are discussed in detail. The relation between swirl ratio and flow coefficient in Ricardo and AVL method, Ricardo and FEV method is analyzed. The swirl ratios measured from the paddle vane and swirl torque meter ,are compared. The methods to judge performance of intake port are presented.
