Analysis of I.C. Engine Fins for Effective Cooling Performance
When fuel is burned in an engine, heat is produced. Additional heat is also generated by friction between the moving parts. Approximately 30% of the energy released is converted into useful work while remaining 70% must be removed from the engine to surrounding, to prevent the parts from overheating. In an air-cooled I.C engine, extended surfaces called fins are provided at the periphery of engine cylinder to increase heat transfer rate. That is why the analysis of fin is important to increase the heat transfer rate. The main of aim of this work is to study different types of fins to improve heat transfer rate of cooling fins by changing cylinder fin geometry.
A Review on Thermal Analysis of Engine Cylinder Fins by Varying Geometry
International Journal of Scientific Research in Science, Engineering and Technology, 2023
Heat transfer by convection between a surface and the fluid surrounding can be increased by attaching to the surface called fins. The heat conducted through solids, walls, or boundaries has to be continuously dissipated to the surroundings or environment to maintain the system in a steady state condition. The cylinder of the engine is one of the key components of the vehicle and is prone to maximum temperature variation and thermal stress. To cool the cylinder, the cylinder fin is designed to improve the heat transfer rate. Thermal analysis is done on the engine cylinder fins; it is very useful to understand the heat dissipation in the cylinder. The idea applied in this project is to increase the heat dissipation rate by using intangible working fluid, just air. It is understood that the heat dissipation rate is increased by changing the surface region; therefore, it is very challenging to design such a huge complicated engine. In this project, the analysis of the engine fin is carried out for different geometries such as Rectangular, Triangular, convex, and Tapered fin. A 3D model is created in SolidWorks and analysis is done using ANSYS Software in steady state condition. The material used for the fin body is Al6063. The result is compared to find the best geometry which gives the maximum heat flux.
Investigation of Fin Thickness on Heat Transfer Characteristics of Engine
International Journal for Research in Applied Science & Engineering Technology (IJRASET), 2023
Fins are one of the important key cooling elements. The main purpose of pin fins is to increase the rate of heat transfer to the surroundings by improving convection. The transferred heat will exist in the form of conduction, convection and radiation. If the temperature coefficient of heat transfer increases, the cooling rate will also increase. The main objective of our project is to increase the rate of heat transfer in different types of fins with different shapes.3D models were designed in Catia and tested in Ansys. Use the developed fins in various applications.
Design Modification and Thermal Analysis of IC Engine Fin – A Review
To study different research papers related to thermal analysis of extended surfaces or projections of materials on the system (engine) called fins of air cooled IC engines. The fins are used to increase the heat transfer rate from the system to the surrounding by increasing the heat transfer area. Fins are used to cool various structures via the process of convection. Generally heat transfer by fins is basically limited by the design of the system. The heat transfer effect may be varied by changing material of different thermal conductivities, improvising engine geometry, increasing cross section area of fins, using perforations on fin and on CFD analysis of fins. Hence the aim of this paper is to study from different literature surveys that how heat transfer through extended surfaces and the heat transfer coefficient affected by changing cross-section this study is useful to know the better geometry and material for the fins for better engine cooling.
Heat Transfer Analysis and Optimization of Engine Cylinder Fins of Varying Geometry and Material
The main aim of the project is to analyze the thermal properties by varying geometry, material and thickness of cylinder fins. Parametric models of cylinder with fins have been developed to predict the transient thermal behavior. The models are created by varying the geometry, rectangular, circular and curved shaped fins and also by varying thickness of the fins. The 3D modeling software used is Pro/Engineer.The analysis is done using ANSYS. Presently Material used for manufacturing cylinder fin body is Aluminum Alloy 204 which has thermal conductivity of 110-150W/mk. We are analyzing the cylinder fins using this material and also using Aluminum alloy 6061 and Magnesium alloy which have higher thermal conductivities.

Heat Transfer Augmentation of Air Cooled 4 stroke SI Engine through Fins- A Review Paper
As energy resources from this world are being depleted day by day in enormous amount. With keeping it as root cause engineers and scientists continually focus over inventing something better rather than existing. In case of automobile the fuel saving is the prime important with minimum emission and best performance. The phenomenon by which heat transfer takes place through engine fins must frequently be improved for these reasons. Fins are extended surface which are used to cool various structures via the process of convection. Generally heat transfer by fins is basically limited by the design of the system. But still it may be enhanced by modifying certain design parameters of the fins. Hence the aim of this paper is to study from different literature surveys that how heat transfer through extended surfaces (fins) and the heat transfer co-efficient affected by changing cross-section, climatic conditions, materials etc.

The Engine cylinder is one of the primary elements of the engine, which is subjected to excessive variation in temperature and thermal stresses. Fins are placed on the surface of the cylinder to enhance the amount of heat transfer by convection. The cooling mechanism of an air-cooled engine is mostly dependent on the fin design of the cylinder head and block. Cooling fins are used to increase the heat transfer rate of a specified surface. The main aim of the project is to study and compare with 100cc hero motorcycle fin and analyze the thermal properties by varying geometry, material and thickness. Presently material used for manufacturing the models is aluminum alloy 6063 which has a thermal conductivity of 200 W/mK. We are changing the material of fins aluminum alloy 6101 which has a thermal conductivity of 218 W/mK. Engine fins and atmospheric air between have force convection occurs. So that using this material we get more heat dissipation from the fin. Also, get more effectiveness of fin than old material. We are considering fin without insulating at the tip. The boundary condition for fin at 1000 ͘͘ °C thermal temp. And 30 ͘͘ °C atmospheric temp.
