Design and Thermal Analysis of 250cc Engine Cylinder Fin by using Different Materials

The 250 cc engine is well-known mechanical component used for power generation, but this is subjected to very high temperature and thermal stresses. Therefore cooling of engine is essential. For this purpose we have two options either we use Liquid cooling system or Air cooling system. Nowadays many of the automotive industries prefers liquid cooling system for higher cc engine but this system have some DRAWBACKS which can be overcome by using Air cooling system(FINS). An air-cooled engine dissipates unwanted heat into surrounding with the help of conduction and convection. We can't increase conductive heat transfer as it is depends on properties of material used, but we can increase convective heat transfer simply by increasing area; therefore to increase area we use outward projections on cylinder called as fins. The main objective of this project is to design and thermal analysis of 250 cc engine cylinder fins by using different materials to replace liquid cooling system. The main purpose of using this FINS is to cool the 250cc engine cylinder by atmospheric air. But for thermal analysis of cylinder fins analyzing software ANSYS .we have to design whole complex 250 cc engine on designing software which is very difficult so a parametric model of engine cylinder with fins is created in 3D modeling software SOLIDWORKS.
