Investigation of the characteristics of multicomponent biodiesel fuel (D-FAME-E) for practical use in Lithuania

Abstract

The results Or studies into tricomponent fuel mixtures containing fossil diesei fuel (D), fatty acid methyl esters (FAME), and ethanol (E) are presented. We propose the possibility of the use of D-FAME-E in Lithuania. We determined the limits of component concentrations that make it possible to produce stable tricomponent fuel mixtures of D-FAME-E.-it different concentrations of ethanol (i.e.. 99.8% and 96%) and at different temperatures (20. 0, and -10 degrees C). Engine tests were performed with fuels prepared according to these conditions. During the performance testing of 2FL511 and IA41 diesei engines, we determined the possible influence of ethanol admixture Oil fuel effectiveness and emission of toxic components Of exhaust gases. Admixture of ethanol increased the indicated efficiency of diesei engines by about 2% and decreased NOx emission by 5-7%. It also decreased the smoke density and increased hydrocarbon (HC) emissions. Particular alterations of fuel characteristics were experimentally fixed for fuels containing ethanol. Technological measures are Suggested for the development of an efficient and stable diesei engine fleet for operation in Lithuania on tricomponent biofuel mixtures, i.e., D-FAME-E.
