Cummins Westport wins PM test grant
Natural gas engine maker Cummins Westport said it has won a $500,000 grant to test catalyzed particulate controls on low-emissions natural gas transit bus engines with the goal of reducing particulate matter (PM) to what it calls "non-detectable" levels. The funding, which is subject to contractual agreements, will be administered by California's South Coast Air Quality Management District (SCAQMD).
