Clean Air Partners (CAP) has received the approval of the California Air Resources Board (CARB) for a new catalytic particulate filter developed for CAP's natural gas and dual-fuel truck engines.
CAP said its filter reduces engine particulate matter (PM) emissions from its dual-fuel truck engines to 0.006 grams per brake horsepower-hour, 40% below the Environmental Protection Agency's 2007 emission standards.
San Diego, CA-based CAP added that its dual-fuel engines do not require ultra-low sulfur diesel in order to meet the 2007 emission standards because its catalytic particulate filter reduces the emissions of non-methane hydrocarbons and carbon monoxide.
