ArvinMeritor has introduced its response to the upcoming tougher emissions regulations for commercial vehicles: the Eliminator.

The solutions, packaged as a system, have a modular approach that can be tailored to specific customer applications with various performance requirements, the company says.

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 2002.

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 oxides of nitrogen (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 company says.

ArvinMeritor metallic substrates offer enhanced value for emissions customers due to the lower precious metal content required per system. The advantages include providing improved emissions performance and better mechanical strength.

In addition, these substrates offer thinner walls than ceramic substrates, which lower backpressure and improve engine performance.

The active system, Eliminator with I.R. Tech has a self-regenerating soot filter system including a diesel burner.
