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 /PRNewswire/ -- 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.
