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. Engine life and effectiveness can be improved with effective cooling. The cooling mechanism of the air cooled engine is mostly dependent on the fin design of the cylinder head and block. Insufficient removal of heat from engine will lead to high thermal stresses and lower engine efficiency. An attempt is made to simulate the heat transfer for different materials and geometry of fins to analyze effects on rate of heat dissipation from fins surfaces. The heat transfer surfaces of Engine are modelled in ANSYS, and the main aim of this work is to study different materials and geometry of fins to improve heat transfer rate by changing fin materials under different conditions. The main of aim of this work is to study various researches done in past to improve heat transfer rate of cooling fins by changing cylinder block fin geometry and climate condition.
