IMPCO and Scania Develop Environmentally Friendly Gas Powered Truck Fuel System

    Eclipse Gas System Seen as Answer to Tighter Emission Regulation in US

    - Environmentally friendly fuel system is extremely clean and quiet while
      offering a new lease on life for older trucks
    - Compressed natural gas (CNG) and liquefied petroleum gas (LNG) systems
      available with over 400 mile range
    - System exceeds Europe's new EURO V emission standard  proposed for 2008

    CERRITOS, Calif., Feb. 1 IMPCO Technologies, Inc.
announced today that it is continuing to participate in a lead
program with Scania Great Britain Limited to develop a new, ultra-low
emissions fuel and engine management system for large trucks that improve
performance, power and mileage while reducing typical diesel emissions by
employing lean-burn natural gas technology.

    Scania (Great Britain) Limited in conjunction with IMPCO Technologies,
Mobil CNG and BG Group developed the program, which revolves around current
Scania 3-Series vehicles that are reengineered for gas operation, and then
recycled into the market place.  The system can be ordered with either CNG or
LNG, operates with much less emissions levels, is quieter and obtains a
operating range of 400 miles.  Mobil CNG and BG Group of the UK install the
refueling stations on the vehicle operator's property to ensure a steady
supply of fuel at all times.
    Central to each gas-truck is the IMPCO Eclipse fuel and engine management
system.  The 32-bit Eclipse processor was specially designed to control the
air/fuel ratio and ignition system.  The Eclipse incorporates a 'knock' sensor
and timing control function, which ensures optimal engine performance and
durability.  Misfire and two levels of redundant self-diagnostics are also
included in the Eclipse software.  The Eclipse is also capable of closed-loop
learning that enables the processor to automatically compensate for fuel
composition shifts in quality while maintaining ultra-low emission levels.
    Dr. Lorne Gettel, Director of IMPCO's Heavy Duty Fuel Systems division,
located in Seattle, Washington said, "Everyone at IMPCO is very pleased to
have attained such tremendous results with the Eclipse system, and to have
surpassed the proposed EURO V emission regulations nearly seven years ahead of
schedule.  Scania and the group members are pushing the envelope on what is
possible to do today to clean the air.  They are a dedicated team of
individuals and easy to collaborate with.  This program demonstrates that
alternative fuels are commercially viable."
    Because gas-powered trucks are extremely clean and quiet, their use should
also help operators overcome many restrictions and curfews imposed against
night-time operation in neighborhoods, city streets, distribution centers and
delivery areas.  Issues relating to pollution and noise have prompted legal
and regulatory actions in some US states such as California.
    "The Eclipse system used in these Scania vehicles is designed to be
modular for ease of maintenance and includes a 'limp-home' mode should there
be a component malfunction.  Almost any diesel engine can be retrofitted with
the Eclipse system, or as an option on new truck vehicles here in the United
States as well as Europe," Lorne added.
