© Springer-Verlag Berlin Heidelberg 2012.Automotive cylinder liners are mechanical components with the function of internal coating of the cylinder automotive engines. The replacement of parts made of steel/cast iron by aluminum alloys has been made with advantages not only in reducing weight as well as fuel consumption and emission of pollutants. This study was aided by the finite element software Hyperworks, where the mesh was generated and the simulation was performed in Abaqus. The mesh for the engine block was defined with elements of four nodes of tetrahedrons. The liners were designed with hexahedron elements of six nodes. Due to the manufacturing process of the cylinder liners (centrifugal casting), the finite elements model was created in layers to meet the variation in the amount of silicon along the wall thickness. The variation in the amount of silicon affects the physical properties of the liners along the wall thickness. With this model, it was possible to show the viability of application of aluminum liners in engine blocks made of cast iron. The modal analysis showed that the model does not contain its first natural frequency within the range of work of the engine, approving its application with this concept.
