The current work determines the rate of heat flow
from an engine cylinder. The heat addition during the heat
addition stage or during explosion is determined by using the
classical equations. The heat dissipation from the cylinder is
enhanced by the fins provided around the cylinder. The results
which are obtained are validated with the finite element
analysis software ANSYS APDL. A study is conducted by
considering various materials to obtain optimum material
selection to enhance the better flow of heat from the system.
