This research aims to explore the possibilities of improving the SI engine's swirl characteristics by means of different change in the geometry of the intake valve. This workaims at improving air-fuel mixing through the replacement of traditional valve with swirling vane surfaces built into the intake valve and a comparison of the proposed geometry. We designed four different types of modified valves, each with different vaneangels, such as Model-1 inlet angel 75°and outlet angel 35°, Model-2 inlet angel 75°and outlet angel 45°, Model-3 inlet angel 65°and outlet angel 30°, Model-4 inlet angel 65°and outlet angel 40°, respectively. The geometry of the intake valves is modelled using CATIA V5 and imported into ANSYS CFD FLUENT code for the simulation of flows. Simulation of the flow is carried by assuming the location of three valve lifts 8mm, 10mm and 12mm respectively. The results obtained are strong, and show that thechanged intake valve has great influence on the characterstics of the swirl.
