Air intake system and filter play major role in getting good quality air into automobile engine. It improves the combustion efficiency and also reduces air pollution. Geometrical design of intake manifold is very important feature for obtaining for the good performance of an I.C. engine. During suction stroke high vacuum pressure is generated which causes flow in the air intake system. Air flow starts from hood to engine intake manifold. Flexible hose is used as a inlet of air in the Air Intake System of the engine which has corrugated structure. Due to high vacuum and fluctuation in air supply, flexible hose lead to cyclic stresses causing fatigue failure. To avoid failure of flexible hose the magnitude of cyclic stresses should be decresed. Aim behind this research work is to find that what type of Geometrical changes are possible in Intake Manifold to overcome the problems associated with it. Guide vanes will be provided in Air Intake pipe of AIS to reduce the pressure drop which occurs in rubber hose. Pressure drop analysis will be compared between conventional geometry of IM and New modified geometry of IM So we can conclude that which geometry is better and provides better flow inside it.
