Proceedings of the World Congress on Engineering 2011 Vol III WCE 2011, July 6 - 8, 2011, London, U.K. Thermal Analysis of SI-Engine using Simplified Finite Element Model Thet T. Mon, Rizalman Mamat, Nazri Kamsah, Member, IAENG  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 2100C to represent occurrence of gasoline combustion. The models and complex boundary conditions [4, 5]. presence of cooling is modeled by assigning convection coefficient on cooling jacket. Material information and The objective of this work is to develop a simplified isotropic material properties are taken from published report. computational
