Abstract
The purpose of this paper discusses the flow structure of inside the cylinder with three dimensional Modeling of in cylinder flow. The results of the CFD simulation can be used to understand the effect of the different obstacles in the flow on the mass flow rate and the static pressure at the tip of the fuel tube. This would be helpful to analyze the pressure loss in the inlet, throat and outlet area. Analysis would be performed to study airflow across carburetor venture by locating fuel tube at the diverging nozzle of the venture and for various positions of throttle plate. In the present paper, fuel tube and throttle plate would be modeled and analyzed in order to have better understanding of the flow in complex venturis. The results of this study for modification of throttle valve design. The carburetor body is remodeled with two throttle bodies replacing conventional throttle. Analysis has been performed to study flow field with modified design and results have been discussed
