Abstract

Abstract

The present study experimentally investigates the performance, combustion, and emission characteristics of a compression ignition diesel engine equipped with a thermal barrier–coated (TBC) piston and fuelled with alumina nanoparticle-enhanced Jatropha biodiesel.  A yttria-stabilized zirconia (YSZ) ceramic coating was applied on the piston crown to reduce heat loss and improve in-cylinder thermal conditions. Jatropha biodiesel blends (B10, B20, and B30) were prepared through transesterification, and alumina (Al₂O₃) nanoparticles at a concentration of 30 ppm were uniformly dispersed using ultrasonication. Experiments were carried out at constant speed under varying load conditions. TBC materials are commonly used on parts such the exhaust valves, combustion chamber walls, cylinder head, and piston crown in internal combustion engines, particularly diesel engines. The results show a reduction in brake specific fuel consumption and a significant improvement in brake thermal efficiency. Nitrogen oxide emissions somewhat increased as a result of higher combustion temperatures, but carbon monoxide and hydrocarbon emissions were significantly decreased. Increased peak cylinder pressure, decreased ignition delay, and improved heat release rate were all found via combustion analysis. The findings verify that applying thermal barrier coating in conjunction with Jatropha biodiesel blended with nanoparticles is a successful strategy for increasing diesel engine efficiency while maintaining acceptable emission characteristics.

As compared to normal diesel operation, the results show that the combination of the thermal barrier coating and the nano-particle enhanced biodiesel blend greatly improved combustion characteristics, resulting in increased brake thermal efficiency and lower fuel usage. Improved oxidation resulted in a significant decrease in carbon monoxide, unburned hydrocarbons, and smoke, according to emission studies; however, a slight rise in NOx emissions was noted, which was explained by higher combustion temperatures inside the coated combustion chamber. All things considered, combining thermal barrier coating technology with Jatropha biodiesel enhanced with nano-particles offers a viable strategy for improving engine performance and lowering toxic emissions in compression ignition engines.
