Determination of the Effects of Some Additives Added to the Mixture of Diesel and Safflower Biodiesel on Exhaust Emissions

Abstract

In this study, linas, a newly developed variety of the safflower plant, were used for biodiesel production. Fuel properties and exhaust emission values of biodiesel fuel (B100) and alternative blended fuels containing different volumetric amounts of diesel (M100), biodiesel (B100) and n-butanol (BU) or n-pentanol (P) (diesel / biodiesel / n-butanol and diesel / biodiesel / n-pentanol) were evaluated in comparison with the reference fuel diesel (M100). In addition, in the study, the effects of 2-ethylhexyl nitrate (EHN) on fuel properties and emission values have been examined by adding EHN cetane improver additive to mixture fuels at a concentration of 2000 ppm. Exhaust emission tests of all fuels and mixtures were carried out in a four-cylinder, four-stroke, and direct injection diesel engine at different speeds and full load conditions. According to the results of the research, the fuel properties of diesel, biodiesel, and blended fuels have been determined that comply with biodiesel and diesel fuel standards. Density values of these fuels were determined between 0.830 to 0.8885 kg m-3, kinematic viscosities 2.83 and 4.57 mm2s-1, calorific values 40.13 and 43.4 MJ kg-1, water content 48.015 and 499 ppm, cetane numbers 48.8 and 55.8, cloud point, cold filter plugging point, and pour point -13.9 and -1.4 ºC, -22 and -10 ºC, -15 and

Comparison of Engine Performance and Emission Values of Biodiesel Obtained from Waste Pumpkin Seeds with Machine Learning

“…Furthermore, they suggested that the increased density of biodiesel compared with diesel fuel amplifies the total fuel mass, consequently leading to slightly higher CO 2 emission values. Similarly, Şahin and Mengeş [48] reported that with an increase in the biodiesel ratio (10% and 20%), the average CO 2 emission values of the fuels across all speeds exhibited increments ranging between 0.2% and 5%.…”
