Analysis of thermal barrier coated pistons in the COMSOL and the effects of their use with water + ethanol doped biodiesel

In this study, the thermal analysis of an aluminum piston coated with MgOZrO2 to create a barrier COMSOL multiphysics program and changes in exhaust gas temperature, fuel consumption, engine torque values obtained as result test experiments were examined. For purpose, uncoated was started biodiesel 5% water + 15% ethanol doped at speeds 1000 rpm, 1500 2000 2500 rpm. results COMSOL, it found that temperature increased upper regions pistons. Likewise, experiments, showed tendency decrease consumption values. It has been observed data are parallel experiments.
