Modal Analysis of Intake Manifold of a Carburetor

Aim of the CFD Analysis is to develop engine performance and condense the emissions. To achieve the extreme mass flow rate and the output velocity should be high with an even distribution to each cylinder for efficient working of the engine. These factors are influence the engine performance such as compression ratio, fuel injection pressure, and quality of fuel, combustion rate, air fuel ratio, intake temperature and pressure, inlet manifold, and combustion chamber designs etc. Optimized geometrical scheme of intake manifold is one of these methods for the better performance of an engine. Optimized Intake manifolds provide better Air motion to the chamber. In the present research two different Manifold Designs viz. With C-D nozzle and without C-D nozzle are used for the Computational Fluid Dynamic (CFD) analysis using k- model to find which model gives maximum Mass flow and Output velocity and hence the performance of Engine can be improved.
