Abstract
Partially Premixed Combustion has provides the advantages of low emissions of nitrogen oxides (NOx) and soot with a simultaneous improvement in fuel efficiency. Research has demonstrated that a load range from idle to full load is possible, when using low-octane-number refinery streams, in the gasoline boiling range. Such refinery streams are likely to be commercially available on the short term.  Consequently, the use of naphtha blends that are commercially available could provide a practical solution.
Researchers report results of a study of three blends which they tested in a single-cylinder engine for emission and efficiency performance.
Besides a presentation of the sensitivity to injection strategies, dilution levels and fuel pressure, emission performance were compared to legislated emission levels. Conventional diesel combustion benchmarks were used for reference to show possible improvements in indicated efficiency.
