Abstract— Simplified finite element model of spark ignition In the light of shortcomings in experimentation,
(SI) engine to analyze combustion heat transfer is presented. researchers have turned their attention to apply computer-
The 2D model is made up with main features of engine aided engineering tool such as finite element method (FEM)
including combustion chamber, valves, manifold, cylinder body,
in the structural and thermal analysis of various engine
piston head and cooling jacket, all projected at the cross section
of the cylinder. The model was discretized with 2D thermal components. Finite element method has been widely used for
elements of global length 0.001. The fuel type is gasoline. solving real world problems due to its capability of modeling
Internal nodal temperature of cylinder body is defined as complex geometries, incorporating a variety of deformation
2100C to represent occurrence of gasoline combustion. The models and complex boundary conditions [4, 5].
presence of cooling is modeled by assigning convection
