Design and Analysis of an Intake Manifold in an IC Engine

Abstract

The paper investigates the properly designed Intake or Inlet Manifold (IM) is vital for the optimal performance of an Internal Combustion (IC) engine. The primary function of the intake manifold is to evenly distribute the combustion mixture (or just air in a direct injection engine) to each intake performance of the engine. Even distribution is important to optimize the efficiency and performance of the engine. It is known that uneven air distribution leads to less volumetric efficiency, increased fuel consumption and also power loss. The main objective of the present work was to make a computational study of flow distribution in an intake manifold under steady state turbulence conditions in the current project work an intake manifold for 3-cylinder engine was modeled and analyzed numerically for evaluating the fluid flow. In this process, the geometric model was created with approximate dimensions (by using curves and points) in ANSA a pre-processing tool and the analysis was carried out using STAR CCM+ which is a solver and post-processing tool port in the cylinder head (s).
