Mack and Volvo have introduced retrofit diesel particulate filters to allow operators of older-model trucks to meet the proposed new emissions requirements in California. The DPFs are designed to work with non-EGR engines sold from 1996 to 2002.
The California Air Resources Board (CARB) intends to improve air quality by reducing particulate matter (PM) emissions from older vehicles. The new requirements apply to all diesel-powered vehicles over 14,000 lb GVWR — including out-of-state vehicles that operate in California, unless they run fewer than 1000 miles and 100 hours a year in the state. Implementation date is Jan. 1, 2011.
Preliminary details regarding the regulations can be found at www.arb.ca.gov/msprog/onrdiesel/documents.htm.
The retrofit DPFs come with a five year/150,000 mile warranty and can be ordered through any Mack or Volvo dealer in the U.S. and Canada. Dealer installation is required. Retrofit DPFs using passive and passive/active regeneration technologies are under development for 2002-2006 EGR engines as well. The retrofits are manufactured by HUSS, LLC of California
