ABSTRACT
In the present work, a simulation model is introduced to investigate the merits of using carbon fiber piston in internal combustion engines. Projected mechanical and thermal stresses are simulated and applied on both traditional aluminum alloy piston and proposed carbon fiber piston using finite element method technique. Operating gas pressure, temperature, and material properties form the basic parameters used for simulation of the proposed piston. ANSYS workbench version 14.5 is used to simulate the results of total deformation, thermal, and stress distribution. The present model was compared to similar previous work to verify its validity. The simulations help to locate the critical areas of maximum stress and temperature distribution which can help in optimizing the design of the proposed carbon fiber piston. The model also shows the influence of thermal conductivity and coefficient of thermal expansion on mechanical properties of the proposed pistons.
