As India has decided to move to BS VI emission regulation by 2020, all original equipment manufacturers (OEM) and Tier 1 suppliers are working towards achieving the goal. Overall reduction in CO2 reduction can be achieved through power to weight reduction of various power train components. In a conventional Multi Point Fuel Injection (MPFI) engine, a fuel rail or delivery pipe is mounted on the intake manifold or cylinder head, which delivers fuel to inlet port at a fuel pressure of 350 kPa to 400 kPa through fuel injectors. In today’s automotive industry most of the fuel rail components are made through PDC process of aluminium because of its ease of availability and machinability. Therefore, several studies have focused on alternate materials like sheet metal and plastic by reducing the weight of the fuel rail. Sheet metal fuel rails can also be made with significant weight reduction. However, their manufacturing processes are complex.

Increasing the efficiency of engine auxiliary systems have become a challenge. Oil pump, identified for this study, is one such engine system which is used for lubrication of engine parts. To achieve higher efficiencies, there is a need for math-based analysis and design. This can be achieved by means of Computational Fluid Dynamics (CFD). The main aim of this paper is to simulate the flow through Gerotor Oil pump using Computational Fluid Dynamics. A 3D model of the entire flow domain is created and meshed in preprocessor GAMBIT. The mesh for various pressure outlet conditions is exported to FLUENT solver for analysis. The predicted results are validated with the experimental results. The comparison shows that the CFD predictions are in good agreement with experimental results. In particular, such a simulation offers a scope for visualizing the flow through the Gerotor oil pump.
