Unsteady flow in the inlet and exhaust systems of Internal Combustion Engines can be simulated with multi-dimensional simulation codes. Due to their computational time, other methods are widely used and give the opportunity of coupling it with a model of the complete engine. This paper reports on an investigation undertaken to compare the accuracy of the method of inertia, the acoustic method and the one-dimensional method for modeling the gas flow in pipe systems. Results of this study give the advantage and disadvantage of each approach. The comparison shows good agreement between one-dimensional and experimental results while the calculation time is kept acceptable.
