| Abstract: | 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. |
