Effect of Ethanol, Biodiesel and Diesel Blend Fuel on Performance and Pollutants Parameters of Diesel Engine

In this research, for correction the combustion properties of biodiesel fuel, ethanol was added. Therefore, effect of using ethanol, biodiesel and diesel blend fuel on MT4-244 diesel engine performance pollutants emission parameters and emission were investigated. The biodiesel in this research produced from waste cooking oil that at (5, 10, 15, 20, 25 and 30% on volumetric basis) blended with Ethanol (2, 4 and 6%), and diesel fuel. So far, 18 samples including variable percent of three fuels were prepared which showed as BED forms. Engine testes were performed on ECE-R96 standard on full load and two engine rotations maximum torque (1300 RPM) and maximum power (2000 RPM). It was found increasing of biodiesel, decreased the pollutant emissions of CO, CO2, PM and HC in comparison to diesel fuel but BSFC and NOx emission increased. It also, Using biodiesel did not change the engine power and torque.
