Abstract

Cetane number (CN) is a measure of the ignition quality of a fuel for compression ignition engines according to the self-ignition delay and serves a function similar to that of the octane rating method used for fuel for spark ignition engines. If the cetane number of a fuel is to low, chemical compounds known as cetane number improvers may be added to increase both the fuel’s CN and performance. The consideration for and supplementation of cetane number improvers is dependent upon the detailed properties of the particular fuel. In this work, we measured blends of diesel fuel with the following cetane number improvers: amyl nitrate, isoamyl nitrate, isoamyl nitrite, 2-ethylhexyl nitrate, and the multicomponent cetane number improver ORYXE in diesel fuel by use of the advanced distillation curve (ADC) method to determine the amount of cetane number improver in the various distillate volume fractions. Tracking the cetane number improver throughout diesel fuels’ volatility profile provides valuable information about the practicality and suitability of these cetane number improvers. Moreover, it provides the basis for the development of equations of state that can describe the thermodynamic properties of these complex mixtures, with specific attention paid to additives.
