The paper presents selected simulation test results of the air flow through various types of throttle bodies. The experimental tests were mapped in virtual conditions, using the experimental conditions as initial and edge conditions. The geometry was implemented from the Solid Works software into the COSMOS-FloWorks, in which the simulations were carried out. The results represented supplementation to test stand investigations. The comparison of classic, two stage and profiled intake throttles provided answers to the ques-tions related to the necessity to differentiate the structure in order to achieve specific flow characteristics.
