FEV, Inc. Aftertreatment Controller Provides Easy-to-Implement Emission Control

First showing of controller designed for retrofit can immediately impact emission control issues in older vehicles

AUBURN HILLS, Mich., April 10 -- FEV, Inc., announced today that it is showing a new Diesel Aftertreatment Control system at the 2008 SAE World Congress. It is the first time that the system, which was developed in North America, is being shown. Because it features a stand-alone control unit that does not need to be integrated with the Engine Control Unit (ECU), the system offers the potential to significantly impact emission control issues in older model vehicles due to the possibility of retrofitting the system. The announcement was made by Dr. Dean Tomazic, vice president, Engine, Performance and Emissions Division, FEV, Inc.

"We have made great strides in emission controls, but there are millions of vehicles on the road that produce unacceptable levels of harmful emissions," said Tomazic. "This device promises to provide a practical, cost- effective solution."

The Aftertreatment Controller is capable of operation independent of a sophisticated ECU, and actively controls either an SCR or NOx absorber system. The stand-alone controller interfaces with an existing engine management system and provides precise, closed-loop feedback control.

The controller is designed to be highly flexible, with each unit requiring no software modifications, and simple calibration. Its modular structure allows for easy adjustment, replacement, addition, or removal of control modules.

  Other key features of the device are:
  --  Stand-alone control unit
  --  Communication to the ECU via CAN or other communication protocol
  --  FEV patented controller core features multi-variable control
      algorithms enabling simultaneous lambda and temperature control at all
      times
  --  Base controller structure allows the integration and implementation of
      different emission control technologies such as NOx adsorber
  --  Software development environment allows easy and fast porting to
      various processor platforms
  --  Can be used in various applications such as PM and NOx control
      retrofits

The stand alone Aftertreatment Controller is one of numerous new technologies that will be on display at the FEV exhibit at the 2008 SAE World Congress.
