Multicomponent Biofuels for Agricultural Diesel Machines

Abstract

Biofuels derived from vegetable oils are increasingly used in diesel engines. The article analyzes the physicochemical properties of petroleum diesel fuel and biofuels of various compositions. A technique has been developed to optimize the composition of multicomponent composite biofuels for diesel engines of agricultural machinery. The optimal composition of a mixture of petroleum diesel fuel, rapeseed oil and rapeseed oil methyl ester has been determined, providing the best combination of fuel efficiency and exhaust emissions. The optimization calculations made it possible to select the composition of a multicomponent mixed biofuel for the D-245.12S engine installed on domestic agricultural machines.

The impact of the temperature of rapeseed oil methyl esters on nitrogen oxides emissions

“…• NO X [mg•nm -3 ] -content of nitrogen oxides in exhaust gases; • V [nm 3 •h -1 ] -the amount of exhaust gas emitted by the engine;…”

“…However, in recent years there has been an increase in the interest of politicians and scientists in issues related to climate protection and air quality [2]. Liquid biofuels of vegetable origin can be an ecological alternative to fossil fuels [3][4][5]. They are synthesized by transesterification of vegetable oils with methanol.…”

Investigation of the Influence of Different Vegetable Oils as a Component of Blended Biofuel on Performance and Emission Characteristics of a Diesel Engine for Agricultural Machinery and Commercial Vehicles

“…The inevitable depletion of traditional fossil fuels and the adverse impacts of the burning of fossil fuels on the environment and human health prompted the search for alternative and renewable energy sources [1][2][3][4][5][6][7][8][9]. In this regard, a renewable and sustainable solution is to use biodiesel [1,2,[10][11][12], which is less harmful to the environment [13] and can be directly applied to existing transport infrastructure without significant changes [4,[14][15][16][17][18]. Therefore, biodiesel fuel can be considered as a future fuel to replace fossil fuels [19,20].…”

“…Biodiesel can be used in blends with diesel fuel (DF) [5,6,17,[21][22][23][24][25][26][27][28][29][30], binary blends [16,21,22], ternary blends [6,12,18,[22][23][24], quaternary blends of vegetable oil biodiesel, alcohol and DF [6] or in pure form [24][25][26] without any modifications or configurations of diesel engines [3].…”

“…Biofuels obtained from vegetable oils are of the greatest interest for use in diesel engines. For this purpose, various vegetable oils have been extensively studied: eucalyptus oil [27], Jatropha seed oil [42], Jatropha curcas oil [1,21,28,43,44], palm oil [2,7,11,26,30,40,41,[44][45][46][47], algal oil [10,35], Roselle oil [47], Karanja oil [29,48], crude tall oil [49], rapeseed oil [3,5,15,17,22,24,25,37,[50][51][52][53][54][55][56], castor oil [57][58][59], mustard oil [20,[60][61][62], rice bran oil [29], soybean oil [15,16,…”
