This study explores the pivotal role of a well-designed Intake Manifold (IM) in optimizing the performance of Internal Combustion (IC) engines. The intake manifold serves to evenly distribute the combustion mixture—or air alone, in the case of direct injection engines—thereby enhancing engine intake performance. Uniform distribution is essential for maximizing efficiency and improving overall engine functionality, as uneven airflow can result in diminished volumetric efficiency, higher fuel consumption, and power loss. The primary aim of this research was to analyze flow distribution within an intake manifold under steady-state turbulence conditions through computational methods. For this purpose, a numerical model of an intake manifold designed for a 3-cylinder engine was developed and examined. The geometric model, created with approximate dimensions utilizing curves and points, was prepared using ANSA as a preprocessing tool. Subsequently, the flow analysis was carried out using STAR CCM+, which combines solver and post-processing capabilities integrated with the cylinder head(s).
