ABSTRACT

One of the major mechanical factors which are subjected to high- temperature variations as well as thermal stresses are the cylinders of the engine. Thus, cooling the engine is necessary. For this problem, there are two methods available that are either using a liquid cooling system or an air cooling system. Nowadays, many of the automotive industries prefer liquid cooling systems for higher cc engines, but this system has some drawbacks which can be overcome using an air cooling system (fins). With the help of convection and conduction, an air cooled engine dissipates the unnecessary heat produced in the engine into the surrounding. Conductive heat transfer can't be increased as it depends on the properties of the material used, but as convection basically depends on the area so, convective heat transfer increases simply by increasing area. Therefore to increase the area, outward projections on cylinders are used which are called fins. The primary function of these FINS is to cool the 250cc engine cylinder with atmospheric air. The aim of this paper is to design triangular fins for 250 cc engine cylinders as well as perform thermal analysis on the fins of engine cylinders by using different kinds of materials based on their characteristics such as the ability to replace the liquid cooling system. An appropriate structure is selected for the model of the Fin. However, ANSYS software is used for the thermal analysis of cylinders consisting of triangular fins. In this paper, a parametric model of a 250 cc engine cylinder with fins is created in the 3D modeling software ANSYS Design Modular.
