Engine fuel tests were conducted with an oxygenated fuel called Cetaner blended with conventional diesel fuel to determine its emissions reduction potential. Blends of 10, 20, 30 and 40% by volume were investigated. The test engine was a 1993 Cummins B5.9 diesel rated at 175 hp. Emissions of particulate matter (PM), oxides of nitrogen (NOx), hydrocarbons (HC) and carbon monoxide (CO), along with brake specific fuel consumption (bsfc) were measured during steady state operation at eight engine speed-load conditions. Soluble organic fraction (SOF) analysis was also carried out on the collected PM filter samples.The experimental results showed that the Cetaner blends can substantially reduce PM emissions. Reductions were observed in both the organic and inorganic fractions of the collected PM. On a modal-averaged basis, increasing Cetaner blend levels yielded greater PM reductions, with reductions of about 3-4% observed for each 1% of oxygen blended to the fuel by mass. No large changes in NOx emissions were observed for the test fuels - on a modal-averaged basis the effect ranged from an 5% decrease to a 2% increase.
