Performance and Regulated/Unregulated Emission Evaluation of a Spark Ignition Engine Fueled with Acetone–Butanol–Ethanol and Gasoline Blends

Abstract

An experimental investigation was conducted on the effect of equivalence ratios and engine loads on performance and emission characteristics using acetone-butanol-ethanol (ABE) and gasoline blends. Gasoline blends with various ABE content (0 vol % to 80 vol % ABE, referred to as G100, ABE10, ABE20, ABE30, ABE60, and ABE80, respectively) were used as test fuels, where the volumetric concentration of A/B/E was 3:6:1. The experiments were conducted at engine loads of 3, 4, 5, and 6 bar brake mean effective pressure at an engine speed of 1200 rpm and under various equivalence ratios (ϕ = 0.83-1.25). The results showed that ABE addition in the fuel blends could increase brake thermal efficiency and decrease unburned hydrocarbon (UHC), carbon dioxide (CO), and oxynitride (NO x ). As for unregulated emissions, acetaldehyde and 1,3-budatiene emissions increased with the increased ABE content in blend fuels. Regarding the aromatic emissions, ABE addition led to a decrease in benzene, toluene, and xylene emissions. The study indicated that ABE could be used as a promising alternative fuel in spark ignition (SI) engines for enhancing the brake thermal efficiency and reducing regulated emissions and aromatic air toxics.

“…Benzin içerisinde biyoetanol kullanımı zararlı emisyon CO ve HC'yi düşürmektedir [22][23][24][25][26]. Benzin içerisine etanolbütanol [27][28][29], propanol ve camphor [30] ilavesi benzer sonuçlar vermiştir.

Improvement of Fusel Oil Features and Effect of Its Use in Different Compression Ratios for an SI Engine on Performance and Emission

“…In order to determine the optimal fusel oil-gasoline blend, engine performance and emission values were investigated using the response surface technique (RSM) by operating the engine at a specific load [18][19][20]. The effects of fusel oil on combustion, specifically before and after the removal of moisture content, were examined comparatively and analyzed statistically [21,22]. In other studies on fusel oil, the effects of fusel-gasoline blends on engine performance and emissions were also investigated [8,[23][24][25][26].…”

Investigation on a Novel Mixed Dialkyl Oxalate System as an Oxygenated Fuel Additive

“…Studies found that ABE and gasoline blends could enhance the brake thermal efficiency and reduce regulated emissions and aromatic air toxics. 6 Luo et al 7 studied the sooting tendency of an ABE−diesel blend. It was found that ethanol and butanol in ABE played a positive role in weakening the sooting tendency, while the acetone in ABE had an opposite effect.…”
