The proposed new requirements from the California Air Resources Board (CARB) are intended to improve air quality by reducing particulate matter (PM) emissions from older vehicles. The requirements apply to all diesel-powered vehicles over 14,000 pounds GVWR; this includes out-of-state vehicles which operate in California, as well as vehicles based in the state. CARB projects the use of retrofit DPFs will reduce PM emissions by 13 tons a day in 2014. CARB will offer financial assistance and incentives for the purchase and installation of the DPFs.
Volvo’s retrofit DPF is integrated into existing exhaust systems and offered in several sizes based upon engine displacement and horsepower. Each retrofit DPF comes with an installation kit, complete with brackets, engineered for the customer’s specific Volvo truck model. Dealer installation is required. The DPFs come with a five year/150,000 mile warranty and can be ordered through any Volvo Trucks dealer in the U.S. and Canada.
The DPF uses active regeneration to clear accumulated PM from the unit’s filter element. This involves raising the heat of the DPF by injecting a small amount of diesel fuel, typically after 8 to 10 hours of truck operation. The DPF system includes an electronic control unit which constantly monitors the filter element to precisely control PM accumulation and regeneration. Retrofit DPFs using passive and passive/active regeneration technologies are under development for 2002-2006 EGR engines. The retrofit DPF system is manufactured by HUSS, LLC, Palm Springs, California, a specialist in exhaust aftertreatment for diesel engines.
