Thermal Analysis of Al2O3, TiO2 and SiC Coatings Combustion of a Diesel Engine Piston 3D Finite Element Method

Abstract

In this study, computer-aided modeling program that SolidWorks software 3D modeled an internal combustion diesel piston (AlSi) and layered binding call on the piston (NiCoCrAlY) on Al₂O₃, TiO₂ and SiC thermal barrier by coating with a material, thermal analysis in SolidWorks Simulation software It is made. Soil work / simulation program made to assign materials and mathematical model has been developed. In the thermal analyses of thermal barrier coated pistons compared to standard pistons, an increase of 32-34% was determined in the combustion chamber temperature of the piston, a decrease of 16-18% was determined in the pin housing of piston and a decrease of 34-39% was determined in the piston skirts.

Key Words: 3D Models with Diesel Piston, Piston Ceramic Coating, Thermal Analysis.
