MALVERN, Penn.– The CCRT (Catalyzed Continuously Regenerating Technology) particulate filter has been verified by the U.S. Environmental Protection Agency.

The CCRT system is the first retrofit emissions filter effective on colder-running engines, Johnson Matthey’s Environmental Catalysts and Technologies (ECT) group announced today.

The EPA verification approves Johnson Matthey’s CCRT technology for use in all highway, heavy-duty, medium-heavy duty, and light-heavy duty, urban bus, 4-cycle, and non-EGR diesel engines manufactured between 1994 and 2003.

The CCRT filter reduces emissions including hydrocarbon, carbon monoxide, and particulate matter by more than 90 percent, say company officials. It is designed for applications with exhaust temperatures as cold as 210C for 40 percent of its duty cycle.

Johnson Matthey’s CCRT system is eligible for use in the EPA’s Voluntary Diesel Retrofit Program (VDRP) and other diesel retrofit programs in the U.S.A., and now officially qualifies for government funding.

“The CCRT filter fills the gap that previous diesel particulate filters missed – difficult applications with lower exhaust temperatures,” said Martin Lassen of Johnson Matthey’s ECT Group. “Retrofit aftertreatment remains one of the most cost-effective air quality solutions for diesel vehicles, and Johnson Matthey provides invaluable assistance to fleet owners and managers throughout the process, from funding to design, installation, and operation.”

Built upon the same patented technology as Johnson Matthey’s non-catalyzed Continuously Regenerating Technology (CRT) filter, the CCRT filter is a second-generation diesel particulate filter designed for challenging applications with lower exhaust outlet temperatures. Johnson Matthey has been successfully operating the CCRT filter on school buses in California and Massachusetts with engines models like the CAT 3126, International DT-444 and DT-466, as well as on refuse trucks with the Mack E7. These applications all have average exhaust temperature less than 220C.
