The main goal of this paper are equate behavior of the piston with and without different thermal coating layer on the piston head under thermal and mechanical loads that arise in the piston due to its operating. Three dimensional model of a piston heavy diesel engine has been presented. The governing equations have been discretized using a finite-volume method (FVM) and solved using multi-physics COMSOL package version 5. The results of the numerical model are showing the distribution of temperature, temperature gradients, Von-Mises stresses, and displacement in the diesel engine piston with and without 200 μm of thermal coating layer as (La2Zr 2O7) which have low thermal conductivity. The results show great improving in the performance of the piston with thermal coating layer.
