Particle oxidation catalyst in light duty and heavy duty diesel applications 2007-24-0093

The effect of a novel particle oxidation catalyst (POC®) on diesel particle emissions is studied in heavy duty and light duty applications. Regulated particulate matter (PM) emission measurement is followed by analyzing either soluble organic fraction (SOF) or volatile organic (VOF) fraction. In addition, in heavy duty diesel application, size distributions are measured. Results show that PM reductions as high as 48-79% can be achieved when using POC in combination with a conventional diesel oxidation catalyst (DOC). As expected, the volatile fraction of the PM was very effectively reduced, but also the non-volatile fraction (i.e. soot) was reduced. In tested steady state driving modes soot reduction was found to be 31-55%.
