Potential Ozone Impacts of Excess NO2 Emissions from Diesel Particulate Filters for On- and Off-Road Diesel Engines
| Project Period: | 07/21/2008 - 01/31/2009 |
| Total Budget: | $75,000 |
| Sub-Contractors: | ENVIRON International Corporation

Modern diesel engines are increasingly incorporating into their design a combination diesel oxidation catalyst (DOC) and catalyzed diesel particulate filter (DPF) to meet stringent new PM emissions standards for on-road and off-road vehicles. The DOC/DPF has the potential to create excess NO2 emissions which can impact ozone and PM nitrate formation. ENVIRON will evaluate the ozone impacts of excess NO2 from DPFs using the June 2005 ozone episode developed for DFW in TERC project H60. The TCEQ emissions inventory will provide the fleet characteristics of on-road heavy-duty diesel engines and off-road diesel equipment categories. Estimates of the penetration rates of DPFs and DOCS into these fleets will be made. The latest findings from EPA- and CARB-sponsored research and certification reports will be used to quantify the effect of DPFs on the N02/NOx ratio of emissions.
