【摘要】 从气体动力学临界流量的基本概念出发，对内燃机进气流量进行了理论分析和计算，得到了进气机构有关特性参数的准则数．对文献中广泛应用的进气马赫指数从理论上进行了探讨，这对指导与改进内燃机进气系统的设计有着积极的意义．更多还原

【Abstract】 On the basis of critical flowrate theory in gas dynandcs, the analysis and calculation of intake critical flowrate for internal combustion engines (ICE) are performed. One new dimensionless criterion used to express the parameters of intake critical flowrate is obtained. The effect of Mach index widely used in references and tests is explained theoretically in the paper.更多还原
