Abstract
This paper describes a simulation program of gas exchange processes in a multi-cylinder internal combustion engine and also describes its applicability to automotive engines which are operated under various engine speed and load conditions.
This simulation program has sufficient flexibility to incorporate almost all intake and exhaust systems of today’s high speed automotive multi-cylinder engines.
To improve the predicting accuracy, a finite difference scheme is used for solving equations defining gas flow dynamics in these systems and moreover a modified Constant-Pressure Theory is used for modeling branches of intake and exhaust manifolds.
In order to evaluate the accuracy of the simulation program, predicted results were compared with experimental data and satisfactory agreement was obtained.
