Clean Air Strategic Alliance - Diesel Particulate Filter Final Report
As part of its ongoing interest in exploring ways to reduce vehicle emissions in urban areas, the CASA Vehicle Emissions Team undertook a demonstration project to test the effectiveness of Diesel Particulate Filters (DPF) (specifically the Johnson Matthey Continuously Regenerating TechnologyTM ) under cold weather conditions. The project involved a one-year test of the filter on two diesel buses in Edmonton Transit System’s (ETS) fleet, between January 2003 and January 2004.
The project’s main conclusion was that the DPF worked in Alberta’s climate. Operationally they require ultra low sulphur diesel fuel (ULSD), and are applicable in modern engines with high combustion temperatures. By using diesel particulate filters, it is possible to advance emissions reductions that would otherwise take longer to occur through fleet turnover. The results showed specifically that: Read More
