Abstract: The combustion chamber of an IC engine is subjected to high temperature variations and thermal stresses, on
which fins are mounted in order to cool the cylinder and to increase the heat dissipation rate. In this report thermal analysis
of engine block with fins were analyzed. By doing thermal analysis on cylinder block fins, it is helpful to know the
temperature distribution and heat dissipation inside the cylinder. The principle behind the cooling of the cylinder block is to
provide the fins over the cylinder block by which the heat transfer rate will be increased. In India, generally in two wheelers
air cooled engines are used. For this purpose, extended surfaces i.e. fins are used, which are mounted on cylinder block and
cylinder head. Though the efficiency of cooling in air cooled system is less as compared to the water cooled system still it is
used because of less space available to keep accessories. In this project the extended surfaces i.e. fins of Honda Shine & Bajaj
Discover two wheeler automotives are tested to investigate effect on heat transfer rate by Cross-section, Fin Pitch, Fin
Material and Fin Thickness. The parametric model of engine block fins has been developed in 3D BY Using catia software
and thermal analysis is done on the with holes and without holes fins and to determine heat flux and temperature distribution
Currently the material used for manufacturing cylinder fin body is Aluminum 2014 and grey cast iron proposed material is
Aluminum 6061 addition in this Thesis, materials are also analyzed. The thermal analysis is done using all three materials
by changing geometries that is perforating to the actual model heat dissipation rate.
