“…Reductions in NOx occurred with higher blend levels and EEB co-blended with biodiesel might serve to mitigate elevated NOx production associated with unsaturated biodiesel. Indeed, the ethoxy moiety may be the source of NOx reduction as observed with ether-diesel blends [36][37][38]. Moreover, the ethoxy moiety influences the melting point of EEB such that cloud point should not be a concern for EEB blended fuels, and EEB might be added to high cloud point fuels.…”

The vast majority of energy that powers our global economy is from combustion of fossil fuels with the unintended consequence of increased deposition of carbon dioxide in the atmosphere and oceans. The scientific and technical challenges for the energy sector are to develop renewable energy sources that are sufficient to meet human energy consumption, are economically viable, and are ecologically sustainable. We investigated ethyl 3-ethoxybutyrate (EEB) as a fuel oxygenate in ultra low sulfur diesel (ULSD) with a bench-scale research engine and determined its economic potential as a renewable fuel with technoeconomic modeling using wastewater treatment plant biosolids as the feedstock for poly-3-hydroxyalkanoates (PHB), a bacterial storage polymer from which EEB can be synthesized. EEB blended well with ULSD, andcetane values of 10% and 20% v/v EEB-ULSD blends exceeded 40. A diesel internal combustion engine fueled with 5%, 10%, and 20% EEB-ULSD blends met or exceeded all tested transportation diesel fuel emissions criteria. Inedible organic feedstocks may be used to produce PHB; and thus, EEB might contribute to carbon reductions without compromising performance or air pollutant emissions. However, further research is needed to determine its role in the overall fuel portfolio.

Increasingly stringent emissions regulations and environmental concerns have caused interest in the development of alternative fuels for internal combustion engines. Recently biobutanol, bioethanol and biodiesel emerged as an alternative fuel due to their oxygenated nature. This paper investigates the physical stability of ethanol-diesel blends using Cottonseed oil methyl esters diesel emulsifier as additives, subsequently analysis of physio-chemical properties. Furthermore, experimental tests were carried out to study the performance (fuel consumption, thermal efficiency, power, exhaust gas temperature) and emissions (CO, NOx, HC and Smoke) of Direct Injection (DI) engine fuelled with the various blends compared with those fuelled by diesel. The blends used for this study were D50B50, D60B30E10, D60B20E15DEE5 And D40B40E10DEE10.

“…Addition of diethyl ether to these mixtures resulted in significant reductions in NOx emissions at low and medium loads. However, NO x emission was higher compared to diesel, and it lower compared to biodiesel blend at high loads [7]. Verma et al looked at the effect of ethanol (E)-methanol (M)-diesel-microalgae biodiesel (S) blend on engine performance and emissions.…”

In this study, the effects of adding ethanol and diethyl ether to diesel fuel on combustion characteristics and NO emissions were numerically investigated. 100% diesel fuel (D100) and by volume 90% diesel+10% ethanol blend (D90E10), 80% diesel+20% ethanol blend (D80E20), 80% diesel+10% ethanol+10% diethyl ether blend (D80E10DEE10) and 85% diesel+ 10% ethanol+5% diethyl ether mixture (D85E10DEE5) was used as fuel. Analyzes were carried out using a single cylinder direct injection diesel engine at 2000 and 3000 rpm engine speed conditions. AVL FIRE software was used for numerical study. In-cylinder pressure, cumulative heat release rate, turbulent kinetic energy (TKE), NO emissions and velocity distributions in the combustion chamber were investigated for five different fuel types. As a result, the in-cylinder pressure and heat release rate of ethanol and diethyl ether blended fuels were lower than diesel fuel at both speeds. This is due to the calorific value of the fuel. It was observed that NO emissions decreased as the ethanol content in the fuel increased. For both engine speeds, the highest TKE value was obtained in D90E10 mixed fuel, and the lowest value was found in D80E10DEE10 mixture fuel. Ethanol positively affected the turbulent kinetic energy. The flow rate of ethanol was higher than diesel and diethyl ether fuel.
