| Summary: | The subject of this paper is modeling of an intake manifold of a four-stroke
IC engine using contemporary software tools. Virtual 3D CAD model of an
intake manifold was designed based on a real intake manifold of a
four-stroke IC engine. Based on the CAD model a 3D CFD model of the intake
manifold was created. The modeling has been done with the purpose of
simulation of the air flow inside the intake manifold in order to monitor
values of the internal pressure during several seconds of the engine
operation in three different operating points. Also, an experiment was
conducted, which included measurements of intake manifold pressure in the
same engine operating points in the course of a time interval of
approximately the same duration. The results of both the simulation and the
experimental measurements have been shown in the paper proving that the
created model was good enough for the intended purpose.
