COMPARING DIFFERENT VALVE LIFTS IN AN IC ENGINE USING COLD FLOW SIMULATION

Fluid flow dynamics inside an engine combustion cylinder plays an important role for air-fuel mixture preparation. IC Engine model is developed using CATIAV5R20 tool. The model is then imported to Finite Element preprocessing tool HYPER MESH for the meshing analysis. The model is then imported to Finite Element solver tool. ANSYS FLUENT is used for post processing the results. The flow dynamics inside the cylinder for different minimum valve lift is studied using FEA. Dynamic motion is visualized and velocity magnitude is plotted for different crank angle from 0° to 730°. Finally velocities and crank angles for various valve lifts are compared
