This paper describes a methodology that has been developed to facilitate a detailed study of
molecular composition effects on particulate matter emissions in advanced diesel engines. This
includes a sophisticated numerical optimization algorithm to formulate well-characterized diesel
fuel blends and an analytical method to characterize diesel fuels more accurately than previously
possible. These tools are described, together with application to the formulation of test fuels with
identical boiling point distribution and cetane number, but differing molecular composition. Test
results are discussed from an advanced high-speed direct injection diesel engine for several of
these fuels, demonstrating the improved insight and understanding available from these combined
techniques.

Significant improvements in the efficiency and emis-
