Increase the Efficiency of Internal Combustion Engine Fin by Replacing the Conventional Fin with Parabolic Fin

Energy conservation and efficiency have always been the quest of engineers concerned with IC engines. In 1882, Sir Dugald Clerk showed the efficiency of the Otto cycle to depend solely upon the expansion ratio. As we know, if excess heat is not removed, engine components fail due to excessive temperature. Only approximately 25-30% of the energy released is converted into useful work. The remaining (70%) must be removed from the engine to prevent the parts from melting. This paper is related to increase the efficiency of fins used in two wheeler four stroke internal combustion engine.
