Abstract
The current study focuses on how a thermal barrier coated piston affects the diesel engine's efficiency and emission criteria. The top surface of the piston crown was completely coated with three varying configurations of thermal barrier coatings (TBC) materials, including 7% YSZ (LHR1), 2% Gd2O3 + YSZ (LHR 2), and 5% Gd2O3 + YSZ (LHR 3), all of which had a thickness of 0.25 mm. In addition, for all three combinations, the bond coat NiCrAlY, which was applied to the sample substrate using plasma spray method. An experimental performance investigation was carried out on a four-stroke, one-cylinder diesel engine fuelled with diesel and mahua bio diesel under various loading situations. A qualitative study was performed to establish the optimal condition using Taguchi's method in order to save time and money.
