SAE 2005- Emitec Introduces Particulate Matter PM Filter Catalyst

DETROIT, April 11 -- Emitec Inc., the world's leading developer and producer of METALIT(R) metallic substrates for exhaust gas aftertreatment, recently introduced its new particulate matter PM Filter Catalyst for both OE and retrofit diesel applications.

"Emitec's PM Filter Catalyst has the potential to reduce particulate matter up to 80 percent, depending on the engine application," said Michael Kerby, president, Emitec Inc. "It also produces minimal impact on total exhaust system backpressure and therefore has a negligible effect on fuel consumption."

The PM Filter Catalyst works on the principle of a partial flow filter, diverting a portion of the exhaust gas as it travels down each channel of the substrate through a stainless-steel sintered, fleece fiber material. PM from the exhaust gas is then deposited in the fleece material for oxidation through a combination of heat and nitrogen dioxide (NO2).

Emitec's PM reduction also offers maintenance-free operation due to the fact that ash does not accumulate. Ash is a natural byproduct of lube oil combustion that occurs inside the diesel engine and is harmless to the environment. Traditional wall-flow filters require ash cleaning as often as every year. Relying on the partial flow concept, however, Emitec's PM filter catalyst allows the ash to pass through the filter so that there is no accumulation and therefore no requirement for cleaning. From the end customer through to the OEM, this is a major advantage in terms of total reliability and cost.

The first OE application on MAN's new D20 engine was announced jointly at the 2004 IAA Commercial Vehicles Show in Hannover, Germany. The first OE application in a diesel passenger car followed in the beginning of 2005. Available retrofit applications include diesel passenger cars offered by major OEMs and trucks through Twin-Tec.

Emitec GmbH is the leading designer and manufacturer of metallic substrates and diesel PM Filter Catalysts for exhaust aftertreatment and evaporative emissions. Founded in 1986, Emitec is headquartered in Lohmar, Germany and currently holds more than 1,400 international patents. The company's North American operations, Emitec Inc., are headquartered in Auburn Hills, Mich. Manufacturing facilities are located in Fountain Inn, S.C. as well as Lohmar and Eisenach, Germany.
