“…However, ethanol has several problems to solve. It can only be used in small concentrations caused by its hygroscopicity and lower energy density than those of conventional fuel [26,27]. In terms of fuel properties, higher alcohol such as butanol is a more favourable alcohol fuel compared to ethanol due to its higher heating value, good solubility and less corrosive to the existing pipelines [28][29][30][31][32].…”

The properties of butanol offer more promising results compared to those of lower chain alcohol such as methanol or ethanol. However, butanol as a biofuel has not yet been commercially produced due to its costly process. Butanol is generally produced via the process of Acetone-Butanol-Ethanol (ABE) fermentation and can only be acquired after it was recovered from the ABE solvent. Despite the efforts and recent developments, obtaining higher butanol concentration from ABE fermentation is still relatively expensive and challenging. The idea of using ABE directly in internal combustion engines is then proposed to eliminate the recovery process. Several preliminary studies have reported several promising results of using ABE blends in both gasoline and diesel engines. However, researches in this area are still in the early stages, and thorough investigations are required. This review paper aims to provide essential findings from the latest development in the addition of ABE both with gasoline and diesel fuel in Spark Ignition (SI) and Compression Ignition (CI) engines. A brief discussion on ABE properties will be firstly given before the effects of its addition on SI and CI engine is comprehensively reviewed. The end of this article highlights some possible contributions and research gaps.

“…The presence of CO 2 in ethanol or in water is known to decrease the pHe or the pH. 51,67,73 CO 2 has a higher solubility in ethanol compared to water. 67 On the other hand, ammonia is less soluble in ethanol compared to water.…”

“…The major drawbacks which are associated with the use of fossil fuel are basically in terms of limited deposit amount, emission which leads to pollution issues, and cost [1,2]. As the world population grows, the quest for more systems that require energy grows higher, such as automotive vehicles, which contribute highly to the emission of greenhouse gases (GHG).…”

This study concentrates on investigating the impact of hybrid additives of ethanol and butanol with magnetite (Iron oxide nanoparticle) added at 100 ppm each to the biofuels, 10% of the resulting nano-biofuel (5% ethanol and magnetite; 5% butanol and magnetite) was then blended with 90% pure palm oil biodiesel (B100). A single-cylinder Yanmar L70N engine was used in the experiment with the resulting fuel. The engine test results indicated that the addition of magnetite nanoparticles in conjunction with the two biofuels significantly reduced brake-specific fuel consumption (BSFC) up to 15.68% (8.8 gm/kW-hr) compared with B100 (10.4 gm/kW-hr) at peak brake power. The break thermal efficiency (BTE) also improved by 4.26% and 9.71% at tested minimum and maximum brake power, respectively. The emission of hydrocarbon (HC), Carbon Oxide (CO), smoke and nitrogen oxide (NOx) were reduced obviously by 14.45%, 11.98%, 7.25% and 5.77% respectively, compared to pure B100 use at peak load. In general, the application of the dual additive approach of combining biofuels and nanoparticles yields positive results due to the improved surface-to-volume ratio of the nanoparticles and good physicochemical attributes of the biofuels, which enhanced the performance of the B100 fuel; thus, more areas should be exploited in these regards.
