Original scientific paper https://doi.org/10.2298/TSCI180707063G The subject of this paper is modelling of an intake manifold of a four-stroke internal combustion engine using contemporary software tools. Virtual 3-D CAD model of an intake manifold was designed based on a real intake manifold of a four-stroke internal combustion engine. Based on the CAD model a 3-D CFD model of the intake manifold was created. The modelling has been done with the purpose of simulation of the air-flow inside the

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.
