The intake system geometry of the internal combustion engine has a major effect on the gas exchange process. Therefore it affects the performance of the engine and its emissions. In order to improve engine performance, it must assure uniform distribution of fresh air among the cylinders and minimal pressure losses along the channels. The optimisation of the intake systems is of an interest to the engine designers sińce the beginning of the 20th century. The paper deals with the optimal design of the intake system for the four-stroke four-valve internal combustion engine with the intention of increasing its power. Special geometry demands and constraints had to be taken into consideration. Optimisation was carried out using the optimisation program iGO based on a gradient-based approximation method. For the response calculation the computational fluid dynamics program BOOST was used. The connection between iGO and BOOST was established by simple wrapper programs that took car e for the correct data exchange. The results comparison confirmed the adequacy of the program BOOST in our example.
