Thermal barrier coated piston experimental investigation in di diesel engines fueled with transformer oil and nanoparticle (alumina)

ABSTRACT

Heat engines are considered for various characteristics, such as durability, performance, and efficiency, to reduce the life cycle cost. The most effective gas turbines tend to make use of more recent developments in cooling and material mechanisms by switching to motor working cycles that use a significant portion of peak turbine inlet temperature ability over the whole working cycle. “Thermal Barrier Coatings (TBC)” carry out the crucial task of isolating portions of petrol generators also plane motors working at high temperatures. TBC is applied on metallic components that are thermally heavily loaded, such as those found in gas turbines. The efficiency of the process is increased by using the TBC, which boosts the process temperature. In this experiment, gadolinium zirconate (Gd₂O₇Zr₂) is administered using the plasma arc method and test blends like B10, B20 and B30 blends were prepared by using waste transformer oil and nano additive and results depict that BTE increases of 1.2% than diesel and also shows lower emissions. Therefore, it is concluded that the TBC-operated CI engine with biodiesel blend shows a positive approach in both performance and emission.
