“…The higher latent heat of ABE compared to G100 caused lower intake manifold temperature and increased volumetric efficiency [41]. In addition, the reduced combustion duration was beneficial for improving thermal efficiency [42]. As expected, the indicated specific fuel consumption (ISFC) increased as the ABE content increased due to the lower LHV of ABE as shown in Fig.…”

“…4(b), a significant reduction in UHC emission was observed for ABE-gasoline blends. This can be explained by the fact that the carbon to hydrogen (C/H) fuel ratio was lower for ABE-gasoline blends, limiting the level of UHC emission [42]. The oxygen content contained in ABE promoted more complete combustion, which also led to the reduced UHC emission.…”

Bio-butanol has proved to be a promising alternative fuel in recent years; it is typically produced from ABE (acetone-butanol-ethanol) fermentation from non-edible biomass feedstock. The high costs for dehydration and recovery from dilute fermentation broth have so far prohibited bio-butanol's use in internal combustion engines. There is an interesting in studying the intermediate fermentation product, i.e. water-containing ABE as a potential fuel. However, most previous studies covered the use of water-containing ABE-diesel blends. In addition, previous studies on SI engines fueled with ABE did not consider the effect of water. Therefore, the evaluation of water-containing ABE gasoline blends in a port fuel-injected spark-ignition (SI) engine was carried out in this study. Effect of adding ABE and water into gasoline on combustion, performance and emissions characteristics was investigated by testing gasoline, ABE30, ABE85,

“…However, the fuel-borne oxygen in IBE could improve combustion quality and increase BTE. In addition, the reduced combustion duration due to IBE addition was also beneficial to improve BTE [40]. For the higher BTE of IBE30, it could be explained that the positive effect of fuel-borne oxygen and reduced combustion duration offset the side effect of improper combustion phasing on the BTE.…”

Among primary alcohols, bio-n-butanol is considered as a promising alternative fuel candidate. However, relatively low production efficiency and high cost of component recovery from the acetone-n-butanol-ethanol (ABE) or isopropanol-n-butanol-ethanol (IBE) fermentation processes hinders industrial-scale production of bio-n-butanol. Hence it is of interest to study the intermediate fermentation product, i.e. ABE and IBE as a potential alternative fuels. However, for fuel applications, the IBE mixture appears to be more attractive than ABE due to more favorable properties of isopropanol over acetone, such as being less corrosive to engine part, higher energy density and octane number. In this study, an experimental investigation on the performance, combustion and emission characteristics of a port fuel-injection SI engine fueled with IBE-gasoline blends was carried out. By comparisons between IBE-gasoline blends with various IBE content (0 vol.%-60 vol.% referred to as G100-IBE60) and more commonly used alternative alcohol fuels (ethanol, n-butanol and ABE)-gasoline blends, it was found that IBE30 performed well with respect to engine performance and emissions, including brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), carbon monoxide (CO), unburned hydrocarbons (UHC) and nitrogen oxides (NO x). Then, IBE30 was selected to be compared with G100 under various equivalence ratio (Φ=0.83~1) and engine load (300 and 500 kpa BMEP). Overall, higher BTE (0.04-4.3%) and lower CO (4%), UHC (15.1-20.3%) and NO x (3.3-18.6%) emissions were produced by IBE30 compared to G100. Therefore, IBE could be a good alternative fuel to gasoline due to the environmentally benign fermentation process (from non-edible biomass feedstock and without recovery process) and the potential to improve energy efficiency and reduce pollutant emissions.

“…The test results showed that the use of ethanol-gasoline and methanol-gasoline fuel blends caused to decrease in CO and unburned HC emissions significantly at the vehicle speed of 80 km/h. Siwale et al [81] studied the effects of blends on performance, combustion and emission characteristics of a single methanol-gasoline with dual alcohol (methanol-nbutanol)-gasoline blend with regard to gasoline fuel. It was found that blend M70 (gasoline/methanol¼30:70) produced less NO x emission than M53b17 (53% methanol, 17% n-butanol and 30% gasoline by volume), blends promoted higher NO x emission than gasoline fuel with the increase of spark timing, and the blend M20 (gasoline/methanol¼80:20) produced the highest NO x emission concentration in both engine variables of spark timing and BMEP.…”
