中文摘要：针对有些模拟计算可以忽略排气压力波的影响,提出了等压法计算的设想,这是一种每一工作循环缸外热力过程只计算一次的简化方法。分析结果表明,这种计算可以满足零维模型必须满足的所有制约方程,能真实地模拟涡轮增压柴油机的实际工作过程,适用于各种增压系统,但仍有待于进一步的研究与改进。根据等压法,建立了一种适用于定压涡轮系统的计算模型———"定压涡轮"模型,用于MPC增压系统的计算,计算结果与试验结果基本吻合,与容积法计算结果趋于一致,从而验证了模型的正确性,同时也表明这种缸外计算法是有效的。

外文摘要：In accordance with some simulated calculations in which the influence of exhaust gas pressure wave may be ignored, constant pressure method calculation conception has been proposed, this is a simplified method in which outcylinder thermodynamic process is only calculated a time every working cycle. The analysis result shows that this calculation can meet all the restricting equations that the zero dimension model must be met ,can really simulate the practical working process of turbocharged diesel engine,and can be applied to all varieties of turbocharging systems,but it will still be studied and improved further. According to constant pressure method, a calculating model 'Constant Pressure Turbine' model for the constant pressure turbine systems has been built up. Then it has been applied to the calculation of MPC turbocharging system,the calculation results are approximately in agreement with the test results and tend to be identical with the calculating results using Filling and Emptying method,so it confirms correctness of the model and effectiveness of this out cylinder calculation method.
