Studies on the Effect of the Zinc Oxide Nano Additives along with Rice Bran Biodiesel Diesel Blends into CI Engine to reduce Pollution

Abstract

Pollution is a major problem for urban cities and its associated industries. The pollution caused by the industries is mainly because of burning of fossil fuels. Some of the pollutants can be controlled by the plantation but the oxides of nitrogen cannot be controlled only by planting trees. Some extra efforts are required to minimize pollution associated with the normal functioning of shop floor of the concerned industries but not affecting its performance. A fuel which suits best for the industrial use is the need of the hour.  In this study, Zinc oxide nanoparticles are used as an additive to the rice bran blended biodiesel and analyze the combustion, performance and emission parameters in a the single-cylinder four-stroke engine water-cooled powered by diesel normally utilised in industries at a constant speed and compression ratio. The available fuel alternatives for testing consist of multiple combinations of diesel fuel and RB biodiesel, each with varying proportions. Furthermore, many gasoline mixes additionally have Zinc Oxide nanoparticles at a concentration of 30 parts per million (ppm). The findings suggest that the brake-specific fuel consumption of Rice bran biodiesel combined with Zinc oxide nano additive exhibits a consistent enhancement, but the brake thermal efficiency declines in comparison to diesel fuel. The concentrations of hydrocarbon (HC) and oxides of nitrogen (NOX) have been reduced, however there has been a little rise in carbon dioxide (CO2) and carbon monoxide (CO). When rice bran biodiesel fuel combined with Zinc Oxide nano additive was used, an abnormally high exhaust gas temperature (EGT) was detected. According to this research, the addition of Zinc Oxide nano additive to rice bran biodiesel blends improves performance and decreases the noxious exhaust emissions generated by diesel engines.
