“…Nevertheless, our finding is coherent with the study by Ali et al (2014), that reported the density decreased with the addition of oxygenates additive such as alcohol and ether to palm oil methyl ester. Venkatesan et al (2017) in their study also revealed that, the density of biodiesel blends from Jatropha oil were gradually reduced with the addition of oxygenates. Generally, addition of suitable oxygenates additives, such as glycerol based oxygenates compound to palm biodiesel, can potentially reduce its density.…”

“…Alhassan et al [35] reported the viscosity of the cottonseed biodiesel as 4.38 mm 2 /s at 40°C. Similarly, Venkatesan et al [36], Alptekin and Canakci [37] and Ramirez-Verduzco et al [38] addressed promising viscosity values for the cottonseed biodiesel as 3.75, 4.06 and 4.12 mm 2 /s, respectively. As these values were lower than the upper limit of the BS EN 14214 standards, blends of the cottonseed biodiesel with the chicken fat biodiesel may comply with the standards.…”

Although waste animal fats such as chicken fat are promising alternative energy sources, biodiesels produced from these type of feedstocks hardly satisfies the EN14214 biodiesel standards. In this study, biomixtures were prepared by blending cottonseed biodiesel and chicken rendering fat biodiesel which were produced via transesterification method. Biodiesels were blended with each other at 60/40, 50/50 and 30/70 volume ratios to produce CO60CH40, CO50CH50 and CO30CH70 fuels. First, fuel properties of the neat biodiesels and novel biomixtures were measured and compared to European biodiesel standards and diesel. Then, the engine performance, combustion characteristics and exhaust emissions of these novel biomixture fuels were measured in a three-cylinder indirect injection diesel engine under various engine loads and at constant speed of 1500 rpm. The fuel characterisation showed that CO60CH40 and CO50CH50 biomixtures met the European standards. The Brake Specific Energy Consumption (BSEC) and Brake Thermal Efficiency (BTE) of all biomixtures were comparable with CO100, CH100 and diesel at the full engine load. The combustion results revealed that the maximum in-cylinder pressure and energy release values of the CO50CH50 were 4.2% and 4.4% higher than the diesel at full engine load because of optimised fuel properties of biomixture such as molecular structure, viscosity, cetane number and iodine value. CO50CH50 had 2.9% reduced CO2 and comparable CO emission compared to diesel, which were also 5.6% and 13% lower than cottonseed biodiesel respectively. However, NO emission of CO50CH50 was found 3.8% and 5.8% higher than diesel and cottonseed biodiesel. A 6.5% reduction on NO emission was observed when CO60CH40 biomixture fuel was used instead of diesel. To conclude, this research showed that blending of cottonseed and chicken fat biodiesels is a promising approach to meet the EN14214 standards, improve in-cylinder pressure, optimise energy release and reduce exhaust emissions. Blending of different biodiesels will be tested as a future work.

“…Cottonseed biodiesel was prepared from cottonseed oil via transesterification. The fatty acid compositions of the cottonseed biodiesel (chemical profiles) were determined using Flame Ionization Detector-Equipped Gas Chromatography (FID-GC) [19]. The analytical grades of normal butanol (nB) and acetone (A) were used with 99.8% purity, and ethanol was used with 100% purity.…”

This study investigates the impact of an acetone-butanol-ethanol (ABE) mixture on spray parameters, engine performance and emission levels of neat cottonseed biodiesel and neat diesel blends. The spray test was carried out using a high-speed camera, and the engine test was conducted on a variable compression diesel engine. Adding an ABE blend can increase the spray penetration of both neat biodiesel and diesel due to the low viscosity and surface tension, thereby enhancing the vaporization rate and combustion efficiency. A maximum in-cylinder pressure value was recorded for the ABE-diesel blend. The brake power (BP) of all ABE blends was slightly reduced due to the low heating values of ABE blends. Exhaust gas temperature (EGT), nitrogen oxides (NOx) and carbon monoxide (CO) emissions were also reduced with the addition of the ABE blend to neat diesel and biodiesel by 14–17%, 11–13% and 25–54%, respectively, compared to neat diesel. Unburnt hydrocarbon (UHC) emissions were reduced with the addition of ABE to diesel by 13%, while UHC emissions were increased with the addition of ABE to biodiesel blend by 25–34% compared to neat diesel. It can be concluded that the ABE mixture is a good additive blend to neat diesel rather than neat biodiesel for improving diesel properties by using green energy for compression ignition (CI) engines with no or minor modifications.
