摘　　要：本文根据增压四冲程柴油机进气特点，假定进气气流为一元不可压缩准稳定的流动，推导出用无因次参数表示的进气系统部件尺寸配合的简化数学模型。按此方法确定的进气系统尺寸可提高充气系数而改善柴油机的经济性，并且已经为６１６０Ａ型增压四冲程柴油机的试验所证实。On the basis of the characteristics of inlet process of supercharged four stroke diesel engine, assuming that air flow is one dimensional quasi steady incompresseble flow during charge, the authors present a simplified dimensionless mathematical model for determining the optimum component size matching of the intake system, which brings about an improvement of fuel economy due to the increase of charging coefficient, and which is verified by the experimental results of Model 6160A supercharged four ...
