AN INVESTIGATION OF EFFECT OF BIODIESEL AND AVIATION FUEL JetA-1 MIXTURES PERFORMANCE AND EMISSIONS ON DIESEL ENGINE

Abstract

Biodiesel is an alternative fuel for diesel engines which does not contain pollutants and sulfur; on the contrary it contains oxygen. In addition, both physical and chemical properties of sunflower oil methyl ester are identical to diesel fuel. Conversely, diesel and biodiesel fuels are widely used with some additives to reduce viscosity, increase the amount of cetane, and improve combustion efficiency. This study uses diesel fuel, sunflower oil methyl ester and its mixture with aviation fuel JetA-1 which are widely used in the aviation industry. Fuel mixtures were used in 1-cylinder, 4-stroke diesel engine under full load and variable engine speeds. In this experiment, engine performance and emission level are investigated. As a conclusion, as the JetA-1 ratio increases in the mixture, lower nitrogen oxide emission is measured. Also, specific fuel consumption is lowered.
