Abstract

To determine the influence of physical and chemical properties of fuels' load range capacity in partially premixed combustion, seven fuels have been blended, with a fixed RON70 reactivity. Four of these fuels are blended from refinery streams, with different boiling ranges, aromatic- and bio-content. Furthermore, three ternary mixtures of Toluene, n-Heptane, Ethanol and iso-Octane are used, of which the aromatics (toluene) and oxygenate (ethanol) content are varied. The load range capacity of these fuels is determined based on their fuel efficiency, smoking tendency and its sensitivity to the fuel pressure used, nitrogen oxides emissions, and combustion efficiency and stability at low load and engine speed.
