AUDUBON, Pa., Feb. 12, 2014 /PRNewswire/ -- The California Air Resources Board (CARB) has extended and modified its verification of two Johnson Matthey Heavy Duty Diesel (HDD) product lines -- the CRT^® Filter and the A_dvCCRT™ system, both of which now allow greater temperature flexibility and higher horsepower range applicability on diesel engines up to 17 liters and 650 HP, and a range of duty cycles. The verifications came in time to meet the needs of fleet owners who are subject to CARB's Truck and Bus regulation. The regulation applies to nearly all privately and federally owned diesel-fueled trucks and buses operating in California with a gross vehicle weight rating (GVWR) greater than 14,000 pounds.

Ajay Joshi, Retrofit Commercial Manager for Johnson Matthey, said the CRT filter has revolutionized modern diesel emissions reduction. "It was the first filter verified by EPA and CARB and has become the industry standard for Heavy Duty Diesel Retrofit Technology.

"The CRT filter is now the most trusted filter globally; it has been used for more than 200,000 retrofits. Johnson Matthey's customers can be assured that they are purchasing world class products from a company that has pioneered emission controls for diesels."

The A_dvCCRT system is Johnson Matthey's second generation CCRT^® heavy-duty diesel retrofit system optimized for more challenging retrofit applications such as EGR-equipped engines. It has a unique two-stage filter arrangement.

The first stage duplicates Johnson Matthey's patented CCRT filter's pre-catalyst and coated filter with proprietary catalyst formulations to reduce PM. The second stage reduces excess NO₂ with the injection of a tiny amount of hydrocarbon across a decomposition catalyst that converts NO₂ back into NO. Other systems reduce NO₂ in the filter, which limits their ability to reduce PM in all applications.

As the global pioneer and leader in controlling emissions from mobile and stationary sources, Joshi said Johnson Matthey offers very robust, passive solutions for both EGR and non-EGR 1994 to 2006 model year trucks to make them compliant with California's truck and bus regulations. Both CRT and A_dvCCRT systems are passive systems, meaning that they require no operator intervention to clean soot from the filter, and do not raise the temperature of the diesel exhaust.

"We also have a well established and very strong dealer and field support network that offers state-of-the-art care to customers. As a pioneer in emission control technologies and one of the first to be verified by CARB, we specialize in California compliant DPFs. Our OEM and retrofit systems are sold across the globe."

Joshi also stressed that Johnson Matthey maintains a sufficient inventory to handle the aggressive lead times truckers will require to meet the upcoming July 1, 2014 good faith compliance extension.
