“…However, NO x emission levels are the same for all blends except Bu80. Elfasakhany [29] evaluated the effect of low-ratio n-butanol-gasoline blends (3%, 7% and 10% nbutanol volume) in a single-cylinder four-stroke naturally aspirated spark ignition engine. Based on his results, even low fractions of n-butanol percentages can significantly reduce the CO, CO 2 and HC compared with gasoline.…”

“…Biofuels are the most widely used oxygenated additives due to the resulting reduction of particulate matter (PM), carbon monoxide (CO), unburned hydrocarbon (UHC), sulfur dioxide (SO 2 ), and polycyclic aromatic hydrocarbon (PAH) in internal combustion engines [4][5][6]. Among biofuels, bio-butanol, which is considered to a promising alternative fuel, has recently attracted increased attention [7][8][9][10][11]. Bio-butanol offers a number of advantages over ethanol, which is currently one of the most widely used alternative fuels [12,13].…”

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.

“…Several studies have already been performed in order to investigate the use of both types of alcohols in spark-ignited engines, either blended with gasoline [8][9][10][11][12][13][14][15][16][17][18][19][20][21] or as a neat fuel [22][23][24][25][26]. A review of ethanol/gasoline blends impact on performance and emissions of a spark-ignited engine is given in [8][9][10][11][12][13][14][15][16].…”

“…A review of ethanol/gasoline blends impact on performance and emissions of a spark-ignited engine is given in [8][9][10][11][12][13][14][15][16]. In [17][18][19][20][21][22][23][24][25][26] results are given concerning the use of butanol, either blended with gasoline or as a neat fuel, in a spark-ignited engine. By observing these results, it can generally be concluded that the increase in alcohol content in the blend with gasoline, could have a significant impact on engine performance and efficiency only at high alcohol concentrations, if the air-fuel ratio is to be maintained within the same range of values as for the gasoline operation.…”

Much research is ongoing to find suitable alternate fuels in order to reduce the exhaust emission levels without deteriorating the basic performance characteristics of conventional spark-ignited (SI) engines. One of the methods to achieve the above problem is the use of alcohols as full supplement fuels to normal gasoline. At the same time, many related research studies have shown that the use of alcohols has a negative impact on some basic engine performance characteristics, e.g., brake power output, etc. On the other hand, spark timing is one of the critical engine operating parameters that significantly influences the combustion mechanism inside the combustion chamber of a SI engine. Therefore, the primary objective of the present work is to investigate the effect of spark timing on the performance and emissions characteristics of a conventional, four-stroke, SI engine running under three different fuel operating modes, viz. with conventional gasoline or ethanol or butanol. The specific investigation is conducted by using an in-house, comprehensive, two-zone phenomenological model. The predictive ability of the model is tested against pertinent experimental data and it is found that the computed results are in good agreement with the respective experimental ones. For all test cases examined herein, the results concern basic engine performance characteristics, i.e., cylinder pressure, power output, specific fuel consumption etc., as well as NO and CO emissions. The main objectives of the work were to record and evaluate the impact that spark timing has on the performance characteristics and emitted pollutants of a conventional SI engine, operating under either conventional gasoline or ethanol or butanol fuel operating modes. Moreover, it deals with the determination of an optimum combination between the type of fuel used and the spark timing, so that probable undesirable effects on engine performance characteristics would be avoided. By comparing this investigation results, it is revealed that the use of alcohols as a full substitute fuel of gasoline accompanied with an appropriate alteration of the spark timing, could be a promising solution to improving both the efficiency and environmental behavior of a light-duty, spark-ignited (SI) engine, without causing any harmful problems to the engine operational lifetime. The conclusions from the study may prove valuable for the application of this technological solution to existing conventional SI engines.
