TI  - Comparison of functionally graded and ungraded cylinder liners with finite element analysis
AB  - In this study, functionally graded and ungraded Al-Si cylinder liners have been comparedby the finite element analysis. At the beginning of the study, the most sold gasolinepoweredautomobiles in recent years have been investigated and the dimensions of the Al-Sicylinder liner have been determined. Al-Si alloy based cylinder liners with a wall-thicknessof 6 mm and inner diameter of 74 mm, an outer diameter of 86 mm and a length of 165 mmhave 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 outersurfaces of the functionally graded liner are 32 vol.% and 8.5 vol.%., respectively. Theungraded cylinder liner, on the other hand, has a homogeneous structure and the siliconcontent of 21 vol.%. The maximum Von Mises stresses reached as a result of thermal loadsin the functionally graded and ungraded cylinder liners are determined to be 47.526 MPaand 95.951 MPa, respectively. It has been observed that maximum Von Mises stressdecreases by approximately 50% thanks to the functional grading.
