ABSTRACT
The Engine cylinder is one of the major automobile components, which is subjected to high
temperature variations and thermal stresses. In order to cool the cylinder, fins are provided on the
cylinder to increase the rate of heat transfer. By doing thermal analysis on the engine cylinder fins, it
is helpful to know the heat dissipation inside the cylinder. The principle implemented in this project
is to increase the heat dissipation rate The parametric model is created by varying the geometry, rect-
angular, circular and curved shaped fins and also by varying thickness of the fins. The main aim is to
analysis thermal properties by varying geometry, material and thickness of cylinder fins. Transient
thermal analysis determines temperatures Heat flux, Thermal gradient and other thermal quantities
that vary over time. The variation of temperature distribution over time is of interest in many
applications such as in cooling. In this project we have taken rectangular, circular and curved fins of
3mm thickness, initially and reduce the thickness into 2.5mm done analysis on the point “ How the
heat transfer changes by the reducing the thickness of the fin. The accurate thermal simulation
could permit critical design parameters to be identified for improved life. 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
Keywords: Combustion Chamber, Cylinder Walls Aluminum Alloy, Modeling With Design
Parameters, And Analysis In ANSYS.
I. INTRODUCTION
In the paper by Mr. Mehul S. Patel, Mr. N.M.Vora[1]
, the main aim is to analysis thermal
properties by varying geometry, material and thickness of cylinder fins. Transient thermal analysis
determines temperatures and other thermal quantities that vary over time. The variation of
temperature distribution over time is of interest in many applications such as in cooling. The
accurate thermal simulation could permit critical design parameters to be identified for
improved life. In the paper by Pulkit Agarwal, Mayur Shrikhande and P. Srinivasan[2]

facilitate this, fins are provided on the outer surface of the cylinder. An attempt is made to simulate
the heat transfer using CFD analysis. The heat transfer surface of the engine is modeled in GAMBIT
and simulated in FLUENT software. An expression of average fin surface heat transfer coefficient in
terms of wind velocity is obtained. It is observed that when the ambient temperature reduces to a
very low value, it results in overcooling and poor efficiency of the engine. In the paper by U. V.
Awasarmol and Dr. A. T. Pise[3]
, the outcome of experimental study conducted to compare the rate
of heat transfer with solid and permeable fins and the effect of angle of inclination of fins. Permeable
fins are formed by modifying the solid rectangular fins by drilling three inline holes per fin. Solid
and Permeable fin block are kept in isolated chamber to study the natural convection heat transfer.
Natural convection heat transfer through of each of these blocks was compared in terms of variations
in steady state temperatures of base and tip. The steady state temperatures were recorded at constant
heat flux condition. At the same time the steady state temperatures were recorded for different angles
of inclination of fins. Blocks having solid and permeable fins were tested for different inputs
(i.e.15W, 20W). Also the blocks were rotated through the different angles of inclination of fins
(i.e.00
, 150
, 300
, 450
, 600
, 750
, 900
). It is found that using permeable fins, heat transfer rate is
improved and convective heat transfer coefficient increases by about 20% as compared to solid fins
with reduction of cost of the material 30%. And the optimum angle of inclination of fins is 900 i.e.
vertical fins. It is also found out that the permeable fins are cooler than the solid fins and the
minimum base temperature is recorded at 900
angle. In the paper by, A Dewan, P Patro, I Khan,and P
Mahanta[4]
, presents a computational study of the steady-state thermal and air-flow resistance
characteristics and performance analysis through a rectangular channel with circular pin fins attached
to a flat surface. The pin fins are arranged in staggered manner and the heat transfer is assumed to be
conjugated in nature. The body forces and radiation effects are assumed to be negligible. The
hydrodynamic and thermal behaviours are studied in detail for the Reynolds numbers varying from
200 to 1000. The heat transfer increases with an increase of the fin density along the stream wise
direction. For the same surface area and pumping power, the fin materials with large thermal
conductivity provide high heat transfer rate with no increase in the pressure drop. The emphasis of
the present research work is not only to look into the traditional objective of maximum heat transfer
in a heat exchanger, but also to obtain it with minimum pressure drop.

IV.CONCLUSION & FUTURE SCOPE
In this thesis, a cylinder fin body for a 150cc motorcycle is modeled using parametric
software Pro/Engineer. The original model is changed by changing the thickness of the fins. The
thickness of the original model is 3mm, it has been reduced to 2.5mm. By reducing the thickness of
the fins, the overall weight is reduced.
Present used material for fin body is Aluminum Alloy 204. In this thesis, three other
materials are considered which have more thermal conductivities than Aluminum Alloy 204. The
materials are Aluminum alloy 7075, Magnesium Alloy and Beryllium. Thermal analysis is done for
all the three materials. The material for the original model is changed by taking the consideration of
their densities and thermal conductivity.
By observing the thermal analysis results, thermal flux is more for Beryllium than other
materials and also by reducing the thickness of the fin 2.5mm, the heat transfer rate is increased.
The shape of the fin can be modified to improve the heat transfer rate and can be analyzed. The use
of Aluminum alloy 6061 as per the manufacturing aspect is to be considered. By changing the
thickness of the fin, the total manufacturing cost is extra to prepare the new component.
