“…This behavior is due to the increased presence of oxygen in sunflower oil, which improves the combustion process and increases the temperature of the cylinder chamber. Similar behavior is reported by Dueso et al [42].…”

This study investigated the influence of different biodiesel blends produced from residual sunflower oil and palm oil from agroindustry liquid waste on the characteristics of the combustion process, performance, and emissions in a single-cylinder diesel engine. For the analysis of the combustion process, a diagnostic model was developed based on the cylinder pressure signal, which allows the calculation of the heat release rate, the accumulated heat rate, and the temperature in the combustion chamber. This is to assess the influence of these parameters on engine emissions. The experiments on the diesel engine were carried out using five types of fuel: conventional diesel, two biodiesel blends of residual palm oil (PB5 and PB10), and two biodiesel blends formed with palm oil and sunflower oil residues (PB5SB5 and PB10SB5). The engine was running in four different modes, which covered its entire operating area. Experimental results show that the in-cylinder pressure curves decrease as the percentage of biodiesel in the fuel increases. Similarly, the results showed a decrease in the heat release rate for biodiesel blends. The diagrams of the accumulated heat release curves were larger for fuels with higher biodiesel content. This effect is reflected in the thermal efficiency of biodiesel blends since the maximum thermal efficiencies were 29.4%, 30%, 30.6%, 31.2%, and 31.8% for PB10SB5, PB5SB5, PB10, PB5, and diesel, respectively. The emission analysis showed that the blends of biodiesel PB5SB5 and PB10SB allowed a greater reduction in the emissions of CO, CO2, HC, and opacity of smoke in all the modes of operation tested, in comparison with the blends of biodiesel PB5 and PB10. However, NOx emissions increased. In general, biodiesel with the percentage of residual sunflower oil does not cause a significant change in the combustion process and engine performance, when compared to biodiesel that includes only residual palm oil.

“…However at rated load the CO emissions for B10 and B20 blends are less by 11.94% and 7.46% respectively when compared to base diesel. This could be due to the fact that higher content of oxygen in the biodiesel [39], which makes easy burning of the fuel in the cylinder at higher temperature [40].…”

Increasing demand of the carbon fuels in daily life and the global environmental degradation has led to the biodiesel production from non-edible oils because they has high potential as ecological, clean, facile and renewable fuel. In present study, oil is extracted from dried Eruca sativa seeds using mechanical expellers, the oil yield obtained is calculated. By alkaline transesterification, the obtained oil is converted into biodiesel. The physicochemical properties of Eruca sativa biodiesel are tested following ASTM test methods, all the properties satisfies and meet the ASTM D-6751 biodiesel standard specifications. The gas chromatography technique is used for the analysis of fatty acid composition of the biodiesel, which shows that the erucic acid has higher percentage composition. Emission characteristics (i.e. carbon monoxide, carbon dioxide, hydro carbon, nitrogen oxide and smoke) of diesel engine are analyzed for the biodiesel and its blends (i.e. B10, B20, B30, B40 and B100) and are compared with the petroleum diesel. From the emission results obtained it is observed that, the CO and CO2 emissions are lower for B10 and B20 blends whereas the HC emissions are lesser than diesel for all the blends. For B10, B20 and B30 blends the NOX emission and smoke opacity has been reduced when compared to diesel.

“…Vegetable oils are renewable, available and environmentally energy resources, which due to their valuable characteristics can be used for different purposes. For example, the possibility of using vegetable oils for biodiesel production [27,30,31] is being actively investigated. However, at present vegetable oils are mainly applied in the food industry.…”

This paper presents the findings of research into combustion of vegetable oils in the composition of coal liquid fuel. The aim of the research was to study the influence of additives of typical vegetable oils (rapeseed, olive, coconut oil, etc.) on concentrations of anthropogenic emissions during combustion of coal water slurries based on coal processing waste. In order to study the effect of different parameters on the emissions efficiency, the tests were done in different operating conditions: muffle furnace temperature, share of oil (up to 15%) in the mixtures, and oil type. The differences between the concentrations of SOx and NOx in the combustion of typical filter cakes (waste coal), as well as those of suspensions with the addition of vegetable impurities have been investigated. It is shown that the concentrations of SOx can be reduced by 5-63% and those of NOxby 5-62% in comparison with coal liquid fuels based on oil refinery waste. Using the generalizing criterion, the paper illustrates the advantages of adding vegetable oils to enhance the prospects of slurry fuels (even based on coal processing waste) in comparison with coal that is the most dangerous in terms of environmental pollution.
