In this study, three dimensional finite element model of the piston of a CNG engine was made to accomplish thermal and also mechanical stress and deformation analysis. Not only steady state temperatures but also gas pressure were measured. In pu1icular, steady st.1te temperatures measured using standard N' 3-type templug were applied to finite element analysis of thermal stress. 1llennal and mechanical stresses of combustion bowl in open dish-type piston were investigated using Smith diagram of a cast aluminium alloy.<br/> The Following Conclusion can be derived;<br/> (1) The thermal stress distribution in the piston was not critical, but at its combustion bowl lip area, the stress due to thermal and mechanical load were concentrated.<br/> (2) The deformation generated in the area of the crown edge and top land was insignificant under durability test.<br/>
