Increasing Efficiency of Intake Port for SI Engine

The thesis describes design solutions the inlet port of the modern combustion engine. The thesis describes basic properties of the inlet port and the types of flow. It is focused the experimental measure of the real inlet port engine Husaberg. The results of the experimental measure are compared with results of the simulation in software CFD. Moreover, it describes creation of 3D parametric model in software Pro/Engineer based on the real geometry exquired from software ATOS. At the end of the work are compared with results of the simulation origin geometry inlet port with origin inlet valve with different changes shapes of valve
