The US EPA Increases Johnson Matthey’s Verified DOC (Diesel Oxidation Catalyst) PM Reduction and Model Year Coverage to 1988-2006 for EGR and non-EGR Engines
Results from EPA Verification Mandatory In-Use Testing Requirements show that Johnson Matthey’s DCC® (Diesel Catalytic Converter) Reduces PM by as Much as 32% for Ultra Low Sulfur Diesel Fuel
Malvern, PA, September 23, 2010 -- Johnson Matthey reported that mandatory EPA in-use tests it has conducted on its DCC® (Diesel Catalytic Converter) prompted the EPA to extend the model year coverage to 1988-2006 for both EGR and non-EGR engines—now the broadest coverage in the industry.
The results of the Phase I and Phase II tests also proved that the company’s basic DCC emissions reduction device—previously covering 1991 and newer engines and its DOC (diesel oxidation catalyst) solution, actually reduce PM (particulate matter) emissions by an average of 27 percent and can achieve as much as a 32 percent reduction.
In addition, the EPA has raised the DCC’s PM reduction verification level to 25 percent on engine model years from 1998 to 2003.
Eight DOC’s were tested, four for Phase 1 (25 percent of warranty period) and four for Phase II (75 percent of warranty period). All testing, baseline and device, was done using ultra-low sulfur diesel fuel to represent today’s real-world operation.
“Many other manufacturers conduct their tests using other kinds of fuels, which does not reflect current on-road and off-road conditions,” said Marty Lassen, Johnson Matthey’s Director of Commercial Development and Marketing,
“The EPA required, in-use testing,” said Lassen, “also proved that Johnson Matthey’s DCC converter maintains its high performance even after 100,000 miles or more.”
According to Lassen, the test results demonstrate how well Johnson Matthey’s heavy-duty diesel emissions control solutions continue to perform. “As the global pioneer and leader in controlling emissions from mobile and stationary sources, our CRT® diesel particulate filter has revolutionized modern diesel emissions reduction. Today, there are hundreds of thousands of our DOC solutions in operation on both retrofits and original equipment first-fits.”
Johnson Matthey’s DCC converter, which minimizes sulfate formation, has other significant advantages: it reduces HC and CO by more than 40 percent, also operates with 500 ppm Low Sulfur Diesel fuel, reduces odors, seamlessly fits to replace existing mufflers, features fit-and-forget technology requiring no maintenance and works on non-road equipment.
