Experimental Investigation On Effect Of Mgo Nanoparticles On Performance And Emission Characteristics Of Candlenut Oil Methyl Ester.

Background: The escalating global demand for energy is driving a continuous rise in fossil fuel consumption, resulting in its inevitable depletion. The unavailability of fuel leads to an increase in fuel prices. The rise in fuel prices is significantly affecting the economic growth of countries. In this paper a biodiesel from non-edible source candlenut oil is used as substitute to diesel fuel Blend of candlenut oil methyl ester (CME20D80) and diesel, neat diesel is tested in single cylinder four stroke CRDI Diesel engine to check the performance and emission characteristics. To the CME20D80 blend MgO nano particles of size below 100 nm are added in varying quantities like 50 ppm,100 ppm and again tested in the same engine. Results indicated that the efficiency of biodiesel blend is less relative to neat diesel, but with the incorporation of magnesium oxide nanoparticles 2.45% rise in efficiency and 1.66% decrease in specific consumption is observed for CME20D80MgO100 compared to neat diesel. And emissions of HC,CO are decreased remarkably. NOx emissions slightly increased for biodiesel, with addition of nanoparticles to biodiesel blend NOx emissions decreased compared to neat diesel.CO2 emissions increased for all test fuels compared to diesel due to complete combustion.
