The University of Miskolc has previously designed and prototyped several race cars for the Formula Student (FS) competition. Unfortunately, none of these cars utilized air intake systems meeting all the requirements of regulations. Intake system are used to feed the engine with sufficient amount of air for complete combustion inside the combustion chamber to produce maximum power. The air flow during flowing produce sound waves due to rate of turbulence and boundary layer separation, and according to standard regulation this sound should be controlled minimum as possible. Recent advances in modelling procedures for accurate performance prediction have led to the development of modelling methods for practical intake system components in commercial design. Engine designers need simple and fast modelling tools, especially in the preliminary design evaluation stages. In this study, commercial software Solidworks and advanced design software Creo 4.0 were used in addition for that Computational Fluid Dynamics (CFD) analysis is performed. Frequency domain analysis is made to receive behaviour of the entire system under assumed conditions.
