ArvinMeritor to supply GEP with Atomizer technology


ArvinMeritor and General Engine Products, a solely owned subsidiary of AM General, have announced an agreement under which ArvinMeritor will supply its ActiveClean Atomizer technology as part of the emissions control aftertreatment system for GEP’s 2007 Optimizer 6500 V8 TurboDiesel engine line. The aftertreatment system will help the Optimizer engines meet U.S. Environmental Protection Agency (EPA) engine emissions regulations that go into effect in 2007.

“ArvinMeritor’s Atomizer product provides uniform disbursement of diesel fuel into the exhaust stream at the optimal particle size, so that the fuel can provide efficient regeneration of a diesel particulate filter and/or a lean NOx trap,” says Silvio Angori, general manager of ArvinMeritor’s Commercial Vehicle Emissions business. “Unlike systems utilizing engine post-injection, the Atomizer does not contribute to engine oil dilution and thus has no detrimental effect on engine durability.”

The Atomizer is part of a system of aftertreatment components that process diesel engine exhaust to enable engines to meet stringent 2007 EPA emissions regulations. GEP also will utilize exhaust gas recirculation (EGR), oxidation catalysts, particulate filters and NOx traps to meet the new emissions standards, according to Jeff Dowell, director of GEP Engine Engineering. Optimizer engines equipped with the Atomizer will be available for applications such as buses, delivery trucks and other commercial engine users.

ArvinMeritor has a long history in developing advanced emissions-control technologies, starting with the catalytic converter introduced in the 1970s. Its portfolio of advanced emissions-control technologies for the commercial vehicle market includes Selective Catalytic Reduction (SCR) systems, the ActiveClean Thermal Regulator, Thermal Enhancer and Plasma Fuel Reformer. The company also is researching technologies that target both particulate matter and NOx to meet stringent emissions requirements in the United States, Europe and Japan.
