# An Analysis and Calculation of Unsteady Flow through Exhaust System of Diesel Engines

• Publish Date: 1981-04-15
• In this paper we make analysis and calculation for unsteady non-homoentropic flow through earhaust system of diesel engines by means of the characteristic method. With reference to certain rational reduction and treatment introduced into calculation, particularly for boundary conditions,the program of calculation is to have general applicability,while the convergence is quite fast.Finally, we take exhaust system of 6135 tvbocharged engines as an illustrative example, its numerical results are quite good.
