在涡流室柴油机中，需要同时获取涡流室和主燃烧室的气体压力，运用本文所建立的复合模型，可根据测取的一个燃烧室的压力来预测另一个燃烧室的压力文中列出了复合模型的详细算式以Ｓ１９５柴油机为例进行计算，结果表明，预测值与实测值吻合良好文中还对燃烧室连接通道流量系数的计算方法及双韦柏函数的运用进行了分析和讨论
In a vortex chamber diesel engine, the pressure of the vortex chamber and the main combustion chamber needs to be obtained at the same time. Using the composite model established in this paper, the pressure of the other combustion chamber can be predicted based on the measured pressure of one of the combustion chambers Detailed calculation formula of composite model S195 diesel engine is taken as an example for calculation, the results show that the predicted value is in good agreement with the measured value. In this paper, the calculation method of the flow coefficient in the connecting passage of the combustion chamber and the application of the double Weber function are also analyzed and discussed
