Abstract: Today our world runs in this condition only because of invention of internal combustion engine. In internal combustion engine chemical energy of fuel is converted to thermal energy to give a mechanical work output. There is large amount of heat liberated during the combustion of fuel, In which only few amount of energy is converted in to useful work (60 to 80%) and the remaining heat energy is wasted. This heat is first conducted to engine cylinder and convected to air through surface called fins. In an air cooled engine low rate of heat transfer is the main problem. Excess temperature developed in the engine causes thermal stresses on the engine parts and piston sizing. In order to avoid this effect, the heat should be sufficiently removed, for this issue in this paper we discussing the heat transfer of different fin geometry under different forced convection conditions. The efficiency of heat transfer can increase by increasing the heat transfer coefficient. Motorcycle engine releases heat to the atmosphere through the mode of force convection. To solve this, fins are provided on the outer of the cylinder. The heat transfer rate is defined depending on the velocity of vehicle, fin geometry and the ambient temperature. Many experimental methods are available in literature to analyse the effect of these factors on the heat transfer rate. However, different fin geometries are modelled in CATIA V5 software and CFD analysis will be used to simulate the heat transfer of the engine block. The result from the software is compared with the existing geometries. The material used for the manufacturing of fin is aluminium alloy
