The objective of this study is to analyze and predict the flow through the intake manifold using a computational fluid dynamics program (CFD). The performance of internal combustion engine depends of the intake manifold and its components. Three model of the intake manifold flap was created and analyzed by using the commercially available ANSYS software. The volumetric efficiency which affects the engine power and torque is affected by the flow of air in the intake manifold. These paper reviews the work realized by various researchers in the field of variable intake manifold. The CFD plots offers valuable information’s of the flow field and tension distribution in the various part of intake manifold flap mechanism. The results show that the CFD model can be used as a tool for improve and optimize various part of the intake manifold flap.
The objective of this study is to analyze the flow filed in the intake manifold using Computational Fluid Dynamics (CFD). The main function of the intake manifold flap is to regulate the air flow and to uniformly distribute in the cylinders. If the air is distributed uneven to the engine the volumetric efficiency, power and fuel consumption is reduced. The finite element method can be used to optimize the throttle flap. The results in the simulation offer valuable information’s of the flow field in the throttle assembly. The results show that the CFD model can be used as a tool for improve and optimize various part of the intake manifold flap.
