Walker takes diesel technology beyond OE

Tenneco Inc. will introduce Walker replacement Diesel Particulate Filters (DPF) and Diesel Oxidation Catalysts (DOC) for light- and medium-duty applications early next year.

The DPF and DOC units will be available for the following applications: 2008-09 6.4-liter Ford F-250 and F-350 Super Duty; 2007-08 6.7-liter Dodge Ram 2500 and 3500; and 2007-08 6.6-liter Chevrolet Silverado and GMC Sierra 2500.

DPF and DOC products have been used in many light- and medium-duty diesel trucks, SUVs and full-size vans since the 2007 model year, when the U.S. Environmental Protection Agency reduced allowable emissions of nitrogen oxide (NOx) and hydrocarbons (HC) by 50% and particulate matter by more than 90%, according to Tenneco.

A DOC works much like a conventional catalytic converter in creating a chemical reaction that helps clean combustion gases. Usually mounted downstream of the DOC, a DPF features a precisely engineered honeycomb structure that traps microscopic particulates within the exhaust stream.

“Replacing a DPF or DOC is a significant investment for most vehicle owners, and it will be absolutely critical for the service provider to use the right technology for each application,” says Richard Alameddine, Tenneco's vice president of marketing and engineering for the North American aftermarket.

“Because we’re an OE supplier of these components, our engineers understand the unique regeneration requirements and other demands of each vehicle. By choosing the Walker brand, service professionals can be certain they’re getting the right part and the right technology.”
