Students of Faculty of Mechanical Engineering and Naval Architecture within the FSB Racing Team have been competing in Formula Student competitions for years. Formula Student is an international competition for students from faculities of technical studies in which students develop, design and construct their own racing car following certain rules. Formerly developed cars by FSB Racing Team have not been fitted with the turbocharger, nor has this possibility been elaborated in detail, although the rules permit usage of a turbocharger. Given that the rulebook requires a specific turbocharger's accommodation, such that the compressor must be behind the restrictor that limits the maximum possible airflow through the engine, the question arises as to whether its application would significantly improve engine's torque and power figures. Also, it is important to note that the engine used by the FSB Racing Team car and in which a turbocharger would be fitted, is a single-cylinder engine. In this thesis, a simulation model of the existing engine and a simulation model of the same engine fitted with a turbocharger were developed using AVL Boost software. In order to select between the two available turbochargers, the engines were parameterized with the use of a simplified turbocharger model. However, since the exact determination of better turbocharger for an engine of choice was not possible, simulations were carried out for both turbochargers and the comparison between normally aspirated engine and the engines with different turbochargers is given.
