The exhaust manifold is an important component,
although it appears to be simple among engine parts. The effective efficiency
and performance of the engine affect many parameters such as the diameter,
length, material and geometry of the exhaust manifold. In the study presented,
commonly used two manifold designs were drawn in the SOLIDWORKS software. Then,
this manifolds were transferred to the ABAQUS V6.13 software.  The physical properties of gasoline, alcohol
and LPG are used as fluid flow for each manifold. In the analysis, the
pressure, velocity and temperature changes of the manifolds are determined at
the measured points. Gasoline fluid is lower pressure and velocity than the
other two fuels in the type A and type B exhaust manifold. The type A exhaust
manifold compared to type B manifold, higher pressures have been reached in all
three fuels. Therefore, the performance and efficiency of the engine can be
increased with A type manifold.
