The aim of this project is to increase the efficiency and performance of the engine by improving
the design of the intake manifold port. Air or Air fuel mixture inside the intake manifold is one of the
important factors, which governs the engine performance. Hence the flow phenomenon inside the intake
manifold should be fully optimized to produce more engine power with better combustion and further
reduces the emission.
Various journals were reviewed in this paper, and in new engine development the pressure waves for
the intake manifold is designed using Unigraphics NX-8.0 software and simulated using Ansys workbench
14.5 Fluent software, to study the internal air flow characteristic for the multi cylinder diesel engine. The
simulations are carried out by using different steady state conditions Reynolds Averaged Navier Stoke
(RANS) turbulence models such as Standard k-epsilon (k-ε) Re- Normalization Group k-ε (RNG),
Realizable k-ε, k-omega (k-ω) and Reynolds Stress Model (RSM). Modeling and analysis carried out for
conventional existing manifold and results were determined. Also new models created for future simulation
work to study, compare and to provide better performing Intake manifold port.
