Abstract
Although they are amongst the most efficient engine types, compression-ignition engines have difficulties achieving acceptable particulate emission and NOx formation. Indeed, catalytic after-treatment of diesel exhaust has become common and current efforts to reformulate diesel fuels have concentrated on the incorporation of oxygenates into the fuel. One of the best ways to characterize changes to a fuel upon the addition of oxygenates is to examine the volatility of the fuel mixture. In this paper, we present the volatility, as measured by the advanced distillation curve method of a prototype diesel fuel with novel diesel fuel oxygenates: 2,5,7,10-tetraoxaundecane (TOU), 2,4,7,9-tetraoxadecane (TOD), and ethanol/fatty acid methyl ester (FAME) mixtures. As observed in earlier studies of oxygenating additives, the volatile additives cause significant early departures from the distillation curve of diesel fuel. We present the results for the initial boiling behavior, the distillation curve temperatures, and track the oxygenates throughout the distillations. Our purpose in doing so, consistent with our vision for replacing fit-for-purpose properties with fundamental properties, is to enable the development of equations of state that can describe the thermodynamic properties of complex mixtures, with specific attention paid to additives.Citation
