惯性增压是利用进气管内气波的自激振荡,使气波加强,从而达到增压的目的。因此,其效果的好坏取决于进气管的结构尺寸。几年来,通过大量的台架试验和实机使用以及理论分析和计祘,积累了一些有关惯性增压进气管设计的经验,现总结归纳如下。进气管的长度是一关键的尺寸。柴油机进气管内空气的流动是一个不定常的流动过 Inertial pressurization is the use of self-excited oscillation of the gas in the intake pipe, the gas wave to enhance, so as to achieve the purpose of pressurization. Therefore, its effect depends on the structure of the intake manifold size. Over the past few years, through a large number of bench tests and real machine use and theoretical analysis and calculation, accumulated some experience on the design of inertial charge manifold, are summarized as follows. Intake pipe length is a key dimension. The air flow in the intake pipe of the diesel engine is an unsteady flow
