摘　　要：建立小型二冲程汽油机非定常排气流动的数学模型，给出用特征线法求解排气压力波的计算实例。在计算过程中通过迭代不断修正特征线的位置，提高了数值解的精度。计算结果与实测结果相当吻合。This paper presents a mathematical model for the unsteady exhaust flow inthe small two-sroke petrol engine,and gives examples of calculation of exhaust pressurewaves through the method of characteristic.By means of the iterative computations the location of characteristic curve is continuously modified, thus the accuracy of numerical results is much improved. The calculated results are quite in conformity with the actllallymeasured ones.
