“…This could be explained by the higher alcohol content, which leads to a charge cooling effect and lowers the temperature, thus slowing down the postflame oxidation of CO emissions. Previous studies also showed higher CO emissions with higher ABE content due to a shorter combustion duration (higher laminar flame speed due to butanol addition), which also leads to a decrease in postflame CO oxidation [2,[39][40][41]. It is also observed that CO emissions increased with increasing engine loads and equivalence ratios.…”

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.

“…Combustion studies with ethanol in SI engines have been carried out by [2][3][4][5][6][7], focusing on performance characteristics, while others [8][9][10][11] have concentrated on engine emission measurements; most of these were done on Port Fuel Injection (PFI) engines. Very few studies have been conducted in latest technology Direct Injection Spark-Ignition (DISI) engines that are typically very sensitive to fuel properties; more to the point, in some of those studies, certain trends illustrate great diversity.…”

“…For example the studies of Brinkman (1981), , Davis and Heil (2000), Al-Farayedhi et al (2004), Nakata et al (2006), andTopgül et al (2006) focused on performance characteristics, while the works of Guerrieri et al (1995), , Sandiquist et al (2001), and Martinez and Ganji (2006) on exhaust emission measurements. Similarly, the combustion of butanol=gasoline blends with PFI was investigated by Alasfour (1997) and Swaja and Naber (2010) in single-cylinder research engines.…”

Future automotive fuels are expected to contain significant quantities of bio-components. This poses a great challenge to the designers of novel low-CO 2 internal combustion engines because biofuels have very different properties to those of most typical hydrocarbons. The current article presents results of firing a direct-injection spark-ignition optical research engine on ethanol and butanol and comparing those to data obtained with gasoline and iso-octane. A multihole injector, located centrally in the combustion chamber, was used with all fuels. Methane was also employed by injecting it into the inlet plenum to provide a benchmark case for well-mixed ''homogeneous'' charge preparation. The study covered stoichiometric and lean mixtures (k ¼ 1.0 and k ¼ 1.2), various spark advances (30-50 CA), a range of engine temperatures (20-90 C), and diverse injection strategies (single and ''split'' triple). In-cylinder gas sampling at the spark-plug location and at a location on the pent-roof wall was also carried out using a fast flame ionization detector to measure the equivalence ratio of the in-cylinder charge and identify the degree of stratification. Combustion imaging was performed through a full-bore optical piston to study the effect of injection strategy on late burning associated with fuel spray wall impingement. Combustion with single injection was fastest for ethanol throughout 20-90 C, but butanol and methane were just as fast at 90 C; iso-octane was the slowest and gasoline was between iso-octane and the alcohols. At 20 C, k at the spark plug location was 0.96-1.09, with gasoline exhibiting the largest and iso-octane the lowest value. Ethanol showed the lowest degree of stratification and butanol the largest. At 90 C, stratification was lower for most fuels, with butanol showing the largest effect. The work output with triple injection was marginally higher for the alcohols and lower for iso-octane and gasoline (than with single injection), but combustion stability was worse for all fuels. Triple injection produced a lower degree of stratification, with leaner k at the spark plug than single injection. Combustion imaging showed much less luminous late burning with tripe injection. In terms of combustion stability, the alcohols were more robust to changes in fueling (k ¼ 1.2) than the liquid hydrocarbons.
