A comparative review of performance and emission characteristics of diesel engine using eucalyptus-biodiesel blend

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

“…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].…”

“…Biodiesel can be produced from many different feedstocks, including non-edible oils (such as eucalyptus oil [27], Jatropha curcas oil [1,28], carania oil [29], waste vegetable and non-edible industrial oils [20], vegetable oil refinery waste [30,31], vegetable and animal oils [13,32,33], waste tallows [23,34] and vegetable oils [3,13,20,23,[35][36][37], fish oil [13,38], waste frying oils [13,[39][40][41], and various alcohols [6,12,13,22,32,39]). Biofuels obtained from vegetable oils are of the greatest interest for use in diesel engines.…”

“…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,…”

“…Numerous studies have established that biodiesel has a higher cetane number [22,26,27], increased oxygen content [19,22,[24][25][26], and higher density [22,24,26] and viscosity [22,24,26], but is inferior in terms of a lower calorific value [26] and compressibility [22] in comparison with DF. These properties have an impact on combustion and exhaust emissions.…”

“…In this case, problems may arise in the operation of diesel engines. These include the poor quality of fuel injection and spray processes [43,51], resulting from their high viscosity [1,6,11,12,15,21,22,24,26,43,54,64,71] and high density [6,21,22,24,26,27,35,64], and also carbon deposition in the engine combustion chamber [12], impairing piston ring mobility. However, Lešnik L and Biluš I [24] have experimentally shown that pure biodiesel derived from rapeseed oil and its blend with petroleum DF can be used as a substitute for petroleum DF in heavy-duty diesel engines with mechanically controlled injection systems.…”
