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.

“…Their simulations used a precise chemical kinetic mechanism and a well-stirred reactor methodology (Pucilowski et al 2017). Zhang et al (2016) constructed a semi-detailed chemical reaction mechanism for simulating the combustion of acetone and alcohols with diesel mixtures in a constant volume combustion chamber. They obtained reasonable agreement between experimental and simulated data of ignition delay, cylinder pressures, and heat release rates using shock tube and constant volume chamber simulations (Zhang et al 2016).…”

The engine researchers and auto makers are putting out significant effort to develop an alternative to petroleum fueled internal combustion (IC) engines for the production of energy in the automotive. Various emerging technologies like electric vehicles (EVs), fuel cells, hydrogen fueled engines etc. are being used as alternative option for IC engines. Biofuels utilization have shown advantages in terms of minimum modification in the existing engine technologies. On the other hand, spark ignition (SI) engine is being used for two-wheelers, lawn movers, aircraft engines, pumping and electricity generating engines and it may be challenging to replace these working engines in short time and it is expected that SI engine would continue to serve as power generating unit for the coming couple of decades. Alcohols have been treated as alternative fuel for internal combustion engines for a long time especially in SI engines by blending. However, alcohols have a lot of potential to be utilized independently in SI engines. In the present study, a detailed modeling work would be performed to investigate the effect of injection timings on the methanol fueled direct injection (DI) SI engine through one dimensional (1-D) simulations. This study suggested as the start of injection (SOI) situation retarded, the heat release rate (HRR) curve shifted to the left. There is hardly any difference in NOx emission depending on injection timing. With a −31°CA SOI at 3.5 kJ fuel energy content, there is a significant quantity of HC observed due to lower fuel efficiency at much advanced SOI conditions.
