Novel Renewable Additive for Diesel Engines 2014-01-1262

A novel oxygenate, 5-methyl furoate ethyl ester (EF), was made by a chemical process from biomass and ethanol. This compound was then used as a renewable diesel additive at concentrations up to 10 percent by volume. This unique ester, which is similar in composition to a know food additive, was studied for engine performance in comparison with two other oxygenated alternatives (i.e. ethanol - EtOH and ethyl levulinate - EL) and with B20 (20 percent biodiesel). Tests were performed with a 2012 6.7 L Ford diesel engine using the heavy-duty Federal Test Procedure. The emission results indicated that a blend of the ester with diesel was comparable to the base fuel. In addition, the results also indicated that EF reduces the formation of particulate matter (PM) and carbon monoxide. Other properties of EF seem to improve the physical properties of the blended fuel such as lubricity and viscosity when compared to the base fuel.
