ArvinMeritor Commercial Vehicle Exhaust business announced new technologies targeted at meeting upcoming emissions regulations
(October 2002 and 2007).
The solutions, packaged as a system, have a modular approach that can be tailored to specific customer applications with various performance requirements. Two basic designs, a passive system and an active system, can be used for OEM or retrofit applications, and are expected to be available in September.
The Eliminator is a passive system, designed as a stand-alone solution that will replace a truck's existing muffler. One version of the modular design incorporates a diesel oxidation catalyst (DOC) and nitrogen oxides (NOx) catalyst, and coupled with new engine management technologies, is capable of meeting October 2002 U.S. heavy-duty engine emissions regulations. The DOC controls hydrocarbons, carbon monoxide and particulate matter, while the NOx catalyst controls NOx. The muffler, used to control noise, can be tuned specifically to suit the individual customer's application.
The active system, Eliminator with I.R. Tech -- a diesel particulate filter with Intelligent Regeneration Technology -- is a self-regenerating soot filter system that consists of a diesel burner, electronic controls and a high-durability particulate filter. The burner system is controlled by a microprocessor and enables automatic on-demand filter regeneration during vehicle operation.
The burner effectively controls soot through automatic regeneration, which is triggered by the filter-loading amount. In addition, an on-board computer ensures reliable automatic regeneration under all driving conditions and requires no intervention by the driver. The Eliminator with I.R. Tech is targeted to meet October 2002 U.S. heavy-duty engine emissions regulations. To meet 2007 NOx, HC and CO emissions regulations, after-treatment devices can be retrofitted to the active system.
The diesel particulate filter used in the EliminatorTM with I.R. Tech TM requires low maintenance and no precious metals. Moreover, the filter does not require catalytic materials or the use of fuel additives to assist with the regeneration process, thus eliminating sulfur contamination concerns.
