Exhaust Emission of Diesel Engines for Operation of Agricultural Mechanization when Working with Different Biofuels

Abstract

The paper presents the results of the study of the effect of different biodiesel-type fuels produced from the oils of several oilseeds on the exhaust gas composition of a direct injection diesel engine designed to drive smaller agricultural machinery. The fuels obtained in this way are derived from the corresponding oils by the method of esterification using methyl alcohol and a catalyst to give the corresponding methyl esters. The physicochemical characteristics of these methyl esters are approximately equal to the standard Euro diesel diesel fuel. During the research, a comparative measurement of the exhaust gas composition was made, at the propulsion of the engine with these fuels, followed by an appropriate analysis of the results. A suitable research installation has been formed to conduct these studies at the Institute of Motors, Faculty of Mechanical Engineering in Belgrade.
