本文指出柴油机“惯性增压”,是一种气波自激增压的过程,并论述了对其流动过程的电子计算机模拟的方法。以195柴油机为计算示例,作出进气管流动过程的电子计算机模拟。计算结果与实测数据相符。这表明所通过的计算程序,可应用于柴油机“惯性增压”的调试和气波自激过程的气体动力学问题的研究中。 This paper points out that the “inertial pressurization” of a diesel engine is a process of self-boosting air-wave and discusses the method of computer simulation of its flow process. Taking 195 diesel engine as a calculation example, an electronic computer simulation of the intake pipe flow process is made. The calculation result is consistent with the measured data. This indicates that the adopted calculation program can be applied to the study of the gas dynamics of the diesel engine “inertial pressurization” debugging and the air wave self-excitation process.
