In a press release dated July 30, 2003, ArvinMeritor’s Commercial Vehicle Systems business announced that its active diesel particulate filter regeneration system, the Thermal Regenerator, in combination with a Corning DuraTrapTM RC wall flow particulate filter, has received approval for use with European commercial vehicle applications. The approval came from VERT (Verminderung der Emissionen von Real-Dieselmotoren im Tunnelbau), which consists of Swiss, German, and Austrian occupational health authorities that developed methods to evaluate and verify exhaust gas after-treatment systems.
The Thermal Regenerator, which may be used with original equipment and retrofit commercial vehicle and mining applications, senses when the diesel particulate filter is full and regenerates by automatically initiating combustion of the accumulated particulate matter. The system was developed to support worldwide initiatives to improve emissions standards for particulate matter and NOx levels, including the upcoming Environmental Protection Agency 2007 regulations.
"VERT approval is a critical milestone in the ongoing development of the Thermal Regenerator," says Pedro Ferro, vice president and general manager of ArvinMeritor Commercial Vehicle Exhaust and Specialty Products. "This system is unique because it virtually assures regeneration of the filter at any point in the duty cycle.
It comprises a fuel combustion chamber, integrated fuel and air supplies, and a stand-alone electronic control unit. Filter systems are really the only effective means to reduce particulate matter emissions to very low levels."
The VERT testing concluded that the ArvinMeritor Thermal Regenerator with the Corning filter ensured effective regeneration and controlled the particulate matter emissions efficiently by removing up to 99.8 percent of nanoparticles. As part of the verification process, the Thermal Regenerator was fitted to a vehicle and operated for 2000 hours over 56,000 miles. After the road test, there was no deterioration in filtration and regeneration.
