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