Simulative analysis of flow through exhaust manifold for improved volumetric efficiency of multi cylinder petrol engine Available to Purchase

In internal combustion engines, exhaust system plays a vital role in the improvement of the combustion efficiency. A good conditioned exhaust manifold increase the performance of the engine. The work is focused on reducing the backpressure in the exhaust manifold to increase the combustion efficiency using CFD. Flow through the exhaust manifold is analyzed using CFX with pressure and velocity parameters as boundary condition. The existing manifold is modified and the new design is analyzed. The results of new design are compared with the values of the existing model. Graphs are drawn for the new design and are compared with existing manifold. The decrease in back pressure is shown using contour and vector diagram. By comparing the existing and new design, the increase in efficiency is found.
