本文从车用发动机对特性曲线的要求出发,指出了目前广泛应用的涡轮增压器与发动机匹配时的不足,提出了改善其联合工作性能的新方法——复合增压法。它把涡轮增压器和谐振进气系统串联起来,利用进气的动态效应,可获得很高的增压压力,从而得到高的扭矩系数。文中介绍了这种复合增压系统的结构、作用原理、设计要求和在规定转速下进行谐振增压时谐振系统几何尺寸的计算公式。对绍勒尔(Saurer)D4KT复合增压系统的测量,证明了公式的正确性。最后根据这种复
Based on the requirement of vehicle engine characteristic curve, this paper points out the shortcomings of the currently widely used turbocharger when matching with the engine, and proposes a new method to improve its joint working performance - compound pressurization method. It combines the turbocharger and the resonance intake system in series, using the dynamic effect of the intake air to obtain a high supercharging pressure, resulting in a high torque coefficient. This paper introduces the structure, principle of action, design requirements and the calculation formula of the resonant system geometry when the hybrid turbocharger system is pressurized at the specified speed. The measurement of the Saurer D4KT compound pressurization system proves the correctness of the formula. Finally based on this complex
