As first insulation level cylinder head and valves were coated with plasma sprayed yttria stabilized zirconia (Y2O3ZrO2) with a thickness of 0.35mm over a 0.15mm thickness of NiCrAl bond coat (LHR1 engine). At last stage pistons have been coated with the same material and procedure (LHR 2 engine). As the insulation level was increased change in the measured parameter was increased. The results have shown that engine power was increased by 6.6-9.6%, engine torque was increased by 6.9-10%, bsfc was decreased by 4-7.8%, EGT was increased by 13-22%, excess air ratio was decreased by 3-4%, smoke emission was decreased by 10-18% and CO2 emission was increased by 3-6.5%.}, number={2}, publisher={E-Journal of New World Sciences Academy}
