The biggest problem facing internal combustion engine is the decrease of energy efficiency due to thermal losses, which causes an increase in fuel consumption and operating cost, as well as a large amount of burned gas released with major environmental problems resulting. In this context, we will focus in this work about improving the efficiency to minimize all these problems, for this we propose to minimize thermal losses through the use of FGM materials. In this context, a steady state heat conduction analysis of functionally graded cylinder is conducted to present the advantages of using of functionally graded materials over the metallic materials in structures that subject to thermal loads, the study is based on the comparison of temperature distribution along the radial direction of the cylinder between a pure metallic and two different functionally graded models, the geometric parameters and boundary conditions of the studied cylinder are considered similar to four-cylinder engine liners. The materials properties gradation is modelled using the power law distribution and the governing equation of heat conduction are solved analytically, the thermal dependency of the properties is supposed to be neglected, the presented results are obtained by a developed Matlab code and using Ansys software.
