Abstract
Our flnaltarget of this study is developing a simulation technique for predicting the pressure pulsation inside automotive exhausting system. In the simulation technique the pulsations of pressure and flow are assumed to be governed by one-dimensional wave equation and the method of characteristic is used. This paper discusses the verification of the built model under the condition that the gas is air and the temperature through the exhaust system is constant by using pneumatic blower. The exhaust system is modeled by the combination of three fundamental elements (pipe, volume and oriffice). As a result, it is shown that our modeling of the pipe system has good accuracy with the measured pressure.
