假定排气总管中气流按整个容积的瞬时参数是相对稳定的,就可以最广泛应用的数学形式表达废气涡轮增压柴油机的脉冲增压系统。根据数学公式(籍助于电子数字计算机)计算的数据,在满足下列条件时,与试验的结果非常吻合。 Assuming that the instantaneous parameter of the gas flow in the exhaust manifold by the entire volume is relatively stable, the pulse pressurization system of an exhaust gas turbocharged diesel engine can be expressed in the most widely used mathematical form. Calculated on the basis of mathematical formulas (by means of electronic digital computers), the results of the tests are in good agreement with the following conditions.
