This research aimed at determining the effect of exhaust aftertreatment devices and ultra low sulfur diesel (ULSD) fuel on the reactivity of exhaust emissions from heavy duty diesel (HDD) engines. Specifically, the objective of this research was to determine the effect of two diesel particulate filters: Engelhard DPX(TM) and Johnson Matthey CRT(TM), and two ULSD fuels, ECD and ECD1 on the ozone forming potential (OFP) of exhaust emissions from HDD engines. To achieve this objective, data was obtained from the "ECD Study" performed in the Spring 2001 to chemically characterize emissions from trucks and buses operating on the two test fuels. The test matrix included four diesel vehicles and two compressed natural gas vehicles retrofitted with and without passive diesel particulate filters.;The study showed that without any aftertreatment device, the reactivity of emissions from vehicles running on ultra low sulfur diesel fuels was similar to baseline vehicles, which were operating on CARB certification diesel fuel (350 ppm S).
