Enhancement of engine performance by nano-coated pistons fuelled with nano-additive biodiesel blends

Researchers have been interested in making a more energy-efficient engine for a long time. This is because the use of fossil fuels like diesel has grown along with the need for more electricity, industry, and transportation. Thermal barrier coating (TBC) on engine parts has become more popular in recent years because it improves thermal and mechanical efficiency, reduces emissions, and saves fuel. In a similar way, biodiesel, which is safe and made from renewable sources of bioenergy, has been suggested as a good alternative to diesel. The present study aims to increase the efficiency of the diesel engine while simultaneously lowering emissions using a piston with a thermal barrier coating, engine operates on biodiesel blends, and a dosage of nano-additives to minimize emissions,. The engine efficiency of nano additives was found to be about 5.4% higher than that of base diesel, and with 6.5% better fuel consumption. Additionally, nano additives reduced carbon monoxide emissions in the range of 6.1–11% and hydrocarbon emissions in the range of 5.2–9.5%. The results were further analysed using the design of experiment tool to determine the influential parameters.
