“…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.

“…As the fuel temperature is decreased, the energy level is also decreased. Some reduction will occur in the engine power if the lower calorific value biodiesel is used in a diesel engine without modification ( Can, Çelikten & Usta, 2004). Figure 4 shows the variation of brake thermal efficiency with engine speed.…”

This paper presents the study of the effect of temperature on diesel engine performance using a 5% biodiesel blend. A one-dimensional numerical analysis is used to simulate the four-cylinder diesel engine. The diesel engine simulation is used to study the characteristics of engine performance when the engine is operating with a fuel blend as an alternative fuel. The simulations are conducted at full load conditions where the temperature varies from 300 to 500 K. The results show that the maximum brake power and brake torque reduction was 1.39% and 1.13%, respectively for an engine operating with a fuel blend. It is shown that the insignificant different due to the small gap between energy content values. A decrease in the lower heating value caused an increase in the brake specific fuel consumption and thus, a reduction in the brake thermal efficiency of the engine performance at full load.

“…The engine power and torque reduces as the portion of the bioethanol in the fuel blend increases. This is due to the low cetane number and calorific value and higher ignition delay of the blends, compared to diesel fuel (Can et al, 2004;Lu et al, 2005;Yan et al, 2009;Park et al, 2010). Meanwhile, the ignition delay occurred due to the consumption reaction of the hydroxyl radical (-OH), which retains the heat release (Hashimoto, 2007).…”

Bioethanol is a renewable and oxygenated bio-based resource with the potential to reduce particulate emissions in direct fuel injection diesel engines. This study aims to further diminish the outflow of a Diesel Fuel Engine motor fueled by diesel-bioethanol by identifying the most suitable blend by applying various blends of diesel-bioethanol, namely E10, E20, E50, and E80 blends. The Diesel engine had been tested using solely diesel fuel and then with bioethanol blends for comparison purposes. The results show that bioethanol fuel can provide a lower torque for the Diesel engine, but a similar engine performance occurs in terms of Horse Power. However, the presence of bioethanol inside the blended fuels increases the emissions of Unburned Hydrocarbon, (HC), CO, CO 2 , and NOx compared to engines that use only Pure Diesel. E10 has been found as the most ideal blend from all the fuels tested. Further research is required to distinguish the E80 fuel blend, as it is unable to be tested on a 6-cylinder engine, since the standard running Diesel engine suitable for the E80 blend fuel is a single cylinder.
