Comparison of functionally graded and ungraded cylinder liners with finite element analysis

Abstract

In this study, functionally graded and ungraded Al-Si cylinder liners have been compared by the finite element analysis. At the beginning of the study, the most sold gasoline-powered automobiles in recent years have been investigated and the dimensions of the Al-Si cylinder liner have been determined. Al-Si alloy based cylinder liners with a wall-thickness of 6 mm and inner diameter of 74 mm, an outer diameter of 86 mm and a length of 165 mm have been designed. The functionally graded cylinder liner has a twenty-layered structure, and the silicon content of each layer is distinct. Si contents on the inner and the outer surfaces of the functionally graded liner are 32 vol.% and 8.5 vol.%., respectively. The ungraded cylinder liner, on the other hand, has a homogeneous structure and the silicon content of 21 vol.%. The maximum Von Mises stresses reached as a result of thermal loads in the functionally graded and ungraded cylinder liners are determined to be 47.526 MPa and 95.951 MPa, respectively. It has been observed that maximum Von Mises stress decreases by approximately 50% thanks to the functional grading.
