“…Among the biofuels that have found the greatest application in diesel engines, vegetable oils and their derivatives -methyl, ethyl and butyl ethers -should be highlighted [6,7,8]. Research continues on the operation of diesel engines using vegetable oils and their mixtures with diesel fuel, including the search for solutions to injection and atomization problems [9][10][11][12][13][14][15][16].…”

The article discusses the problem of replacing traditional diesel fuel with an alternative one. Rapeseed oil is considered as an alternative motor fuel. A deterioration in the quality of injection and atomization processes was noted when converting the engine to rapeseed oil. Experimental studies of the MD-6 diesel engine have shown that it can operate effectively on both petroleum diesel fuel and rapeseed oil. At the same time, the transfer of this engine from petroleum diesel fuel to rapeseed oil was accompanied by an increase in brake-specific fuel consumption, an increase in exhaust gas opacity, and an increase in emissions of nitrogen oxides and carbon monoxide. These negative phenomena are partly eliminated by adjusting the fuel injection advance angle. Improved engine performance is also achieved by optimizing the characteristics of the fuel supply system and two-phase fuel supply. The implementation of these measures makes it possible not only to achieve the performance of a diesel engine characteristic of running on diesel fuel, but also to meet the requirements for fuel efficiency and exhaust gas toxicity that are promising for small-sized high-speed diesel engines.

“…Compared to the vegetable oils themselves, these esters have a lower viscosity, better volatility, an increased cetane number, and a slightly higher calorific value. However, additional costs for interesterification of vegetable oils and worse environmental properties reduce the competitiveness of these biodiesel fuels [7]. At the same time, vegetable oils can be directly used in diesel engines, especially in the agricultural sector, where vegetable oils can be easily obtained, and additional transportation of oils is not required for their transesterification and consumption in urban areas.…”

The relevance of the article is due to the need to replace petroleum diesel fuel with fuels obtained from alternative raw materials. Rapeseed oil is considered as an alternative motor fuel. The properties of petroleum diesel fuel and rapeseed oil are analyzed. The influence of these properties of fuels on the characteristics of their injection and spraying is investigated. The deterioration of the quality of the injection and spraying processes was noted when the engine was switched from petroleum diesel fuel to rapeseed oil. When replacing diesel fuel with rapeseed oil, a slight increase in the maximum injection pressure and the duration of fuel supply was noted. Other parameters of fuel injection and atomization processes practically did not change. To achieve the required performance indicators of the diesel engine, it is necessary to implement measures that improve the quality of the workflow. These measures include the regulation of the fuel injection advance angle, optimization of the geometry of the flow part of the nozzle sprayer, two-phase fuel supply. It is advisable to switch from rapeseed oil to mixed biofuels and optimize their composition.

“…The fuels produced from vegetable oils are considered promising biofuels for compression ignition (CI) engine applications [10,11,14]. Attributed to the similarity of physical and chemical properties between vegetable-oil-based biofuels and petroleum diesel fuel (DF), vegetable-oil-based biofuels can be used to fuel CI engines without almost any engine modification [15,16]. There are mainly two approaches to use vegetable oils: their direct use (straight vegetable oil-SVO) and their transesterification to fatty acid methyl or ethyl esters-vegetable oil biodiesels (VOB).…”

“…Different methods are used to decrease the viscosity of vegetable-oil-based biofuels. The first is to blend vegetable oils with low viscosity fuels, mainly with petroleum DF [15,25,27,33,34]. Qi D.H. et al [27] experimentally investigated the effect of rapeseed oil (RO) blended DF on combustion and emissions characteristics of a 2-cylinder agricultural diesel engine at an engine speed of 1500 rpm.…”

“…The smoke density of all the linseed-oil blended DF is lower than that of DF except for 50% linseed oil. Based on experimental data Dey P. and Ray S. [15] adopted a response surface approach to optimize the fraction of waste vegetable oil in its blend with diesel fuel for fueling a diesel engine at an engine speed of 1500 rpm. It is found that under an engine torque of 14.72 N•m, in comparison with DF, the CO emission and NOx emission for a blend of 50% waste vegetable oil and 50% DF decreased by 14.3% and 15.0%, respectively, but the HC emission increased by 8.3% and thermal efficiency decreased by 2.0%.…”

The article discusses the possibility of using blended biofuels from rapeseed oil (RO) as fuel for a diesel engine. RO blended diesel fuel (DF) and emulsified multicomponent biofuels have been investigated. Fuel physicochemical properties have been analyzed. Experimental tests of a diesel engine D-245 in the operating conditions of the external characteristic curve and the 13-mode test cycle have been conducted to investigate the effect of these fuels on engine performances. CFD simulations of the nozzle inner flow were performed for DF and ethanol-emulsified RO. The possibility of a significant improvement in brake thermal efficiency of the engine has been noted. The efficiency of using blended biofuels from RO as a motor fuel for diesel engines has been evaluated based on the experimental test results. It was shown that in comparison with the presence of RO in emulsified multicomponent biofuel, the presence of water has a more significant effect on NOx emission reduction. The content of RO and the content of water in the investigated emulsified fuels have a comparable influence on exhaust smoke reduction. Nozzle inner flow simulations show that the emulsification of RO changes its flow behaviors and cavitation regime.
