“…Hagos, et al [148] tried to differentiate emulsification techniques from blending based on the difference in boiling points of the mixtures, stating that blending of a neat fuel mixture can only be convenient for fuels with relatively similar boiling points. Emulsion on the other hand, can only be used for fuel mixtures with different boiling points to demonstrate the benefit of micro-explosion in the fuel atomization.…”

An algal feedstock or biomass may contain a very high oil fraction, and thus could be used for the production of advanced biofuels via different conversion processes. Its major advantage apart from its large oil fraction is the ability to convert almost all the energy from the feedstock into different varieties of useful products. In the research to displace fossil fuels, algae feedstock has emerged as a suitable candidate not only because of its renewable and sustainable features but also for its economic credibility based on the potential to match up with the global demand for transportation fuels. Cultivating this feedstock is very easy and could be developed with little or even no supervision, with the aid of wastewater not suitable for human consumption while absorbing CO2 from the atmosphere. The overall potential for algae applications generally shows that this feedstock is still an untapped resource, and it could be of huge commercial benefits to the global economy at large because algae exist in millions compared to terrestrial plants. Algae applications are evident for everyday consumption via foods products, non-foods products, fuel, and energy. Biofuels derived from algae have no impact on the environment and the food supply unlike biofuels produced from crops. However, any cultivation method employed could control the operating cost and the technicalities involved, which will also influence the production rate and strain. The scope of this paper is to review the current status of algae as a potential feedstock with diverse benefit for the resolution of the global energy demand, and environmental pollution control of GHG.

“…Since bioethanol and diesel got immiscibility issue, biodiesel influence with innovative strategic mixing approach hopefully could be useful. Hagos et al (2016) signified the possible distinction between blending and emulsion on tri-fuel [10]. Thus, instead of casual mixing, this study experimented emulsification approach on tri-fuel with multiple proportion.…”

Abstract. This paper presents the result of experimenting emulsified tri-fuel in term of stability, physico-chemical properties and corrosion effect on three common metals. The results were interpreted in terms of the impact of five minutes emulsification approach. Tri-fuel emulsions were varied in proportion ratio consist of biodiesel; 0%, 5%, 10%, and ethanol; 5%, 10%, 15%. Fuel characterization includes density, calorific value, flash point, and kinematic viscosity. Flash point of tri-fuel emulsion came with range catalog. Calorific value of tri-fuel emulsion appeared in declining pattern as more ethanol and biodiesel were added. Biodiesel promoted flow resistance while ethanol with opposite effect. 15% ethanol content in tri-fuel emulsion separated faster than 10% ethanol content but ethanol content with 5% yield no phase separation at all. Close cap under static immersion with various ratio of tri-fuel emulsions for over a month, corrosiveness attack was detected via weight loss technique on aluminum, stainless steel and mild steel.

“…Third, in addition to the above-mentioned two methods, a dual-fuel approach can also be employed. Both spark-and compression-ignition engines can use dual fuels to increase the thermal e ciency and reduce emissions (Cheng et al, 2008;Hagos et al, 2017;Huang et al, 2017;Bharathiraja et al, 2019). Fourth, novel in-cylinder combustion modes can be established, such as exhaust gas recirculation (EGR), optimized injection strategies, and improved incylinder turbulence or vortex intensities.…”

Background: Methanol is abundant, safe, and environmentally friendly and has physicochemical properties similar to those of gasoline. It is a promising alternative fuel in China because it can be directly used in both spark- and compression-ignition internal combustion engines. The current development of spark-ignition engines focuses on the reduction of the fuel volume and increase in the compression ratio (CR), which would benefit the engine’s thermal efficiency. However, increasing the CR may deteriorate particulate matter (PM) due to the high temperature.Methods: Herein, an experimental study was conducted on methanol–gasoline blends in a spark-ignition engine. We examined the performance and formaldehyde emissions of methanol–gasoline blends by using three volume fractions (M0, M15, and M100). In addition, the effects of the CR on PM emissions were investigated.Results: The following relationships were observed: (1) When methanol was blended with gasoline, the formaldehyde emissions increased significantly. The formaldehyde emissions of 100% methanol were higher than those of the methanol–gasoline blend with a methanol volume fraction of 15%; both of these emissions were higher than those of pure gasoline; (2) Increasing the CR resulted in increased PM emissions; (3) For a given blending ratio, the PM emissions were positively correlated with the CR; and (4) The PM emissions were negatively correlated with the methanol volume fraction.Conclusions: Methanol reduces the heat loss at the wall surface. As the ratio of methanol in gasoline increases, the PM emissions decrease. On the other hand, the PM emissions are positively correlated with the CR. The addition of lower alcohols dilutes the concentrations of soot precursors, thereby reducing the soot emissions.
