IMPCO Announces an Array of Electronic Controls, Algorithms, and Software For the Control of Fuel Cells and Internal Combustion Engines IMPCO TECHNOLOGIES LOGO IMPCO Technologies logo. (PRNewsFoto)[DM] CERRITOS, CA USA 09/21/1999    

    IRVINE, Calif., Dec. 15 -- IMPCO Technologies, Inc.
announced today that its Technology and Automotive OEM
Division, Irvine, C.A., now offers a variety of electronic products and
services for the control of Hydrogen and other gaseous fuels such as
Compressed Natural Gas.  Automotive controllers and mass flow sensors used for
gaseous fuel engine management systems are two important offerings.  To
minimize the impact to OEM hardware and software, IMPCO has designed systems
to handle fuel control and diagnostics in a separate alternate fuel
controller.  Some of the unique inputs and outputs needed for gaseous fuel
systems are not available in today's OEM powertrain controllers.  IMPCO's
proprietary controllers and sensors are designed to meet typical automotive
OEM requirements and have successfully completed all automotive
testing/validation requirements.

    IMPCO is currently in its third year of production with California Air
Resources Board (CARB) OBD II compliant engine/vehicle control modules.
    All circuits, printed circuit boards enclosures and assemblies are
designed in-house at IMPCO's Advanced Technology Center in Irvine.  IMPCO has
engineered controllers capable of communication in J 1850 and CAN
communication.  The control software is written in C++ language.  The IMPCO
Gas Mass Sensor uses hot wire anemometry and incorporates an H-Bridge driver,
which is used to control the IMPCO 1" gas flow valve.  The Gas Mass Sensor
features a microprocessor making the sensor/valve combination a "smart gas
flow controller."

    Syed Hussain, Vice President and General Manager of IMPCO's Technology and
Automotive OEM Division says: "These technologies complement the release of
IMPCO's advanced fuel system technologies in terms of providing environmental
benefits through reduced emissions and increased fuel economy.  They also
further demonstrate IMPCO's core competency in energy and environmental
requirements at a vehicle level."

    IMPCO is the world leader in supply of clean emission alternative fuel
systems to the Original Equipment Manufacturer (OEM) market and aftermarket.
IMPCO develops and manufactures environmentally clean emission fuel systems
for gaseous fuel management (carburetion & injector based technology) and
storage systems (advanced composite hydrogen & CNG storage) as well as various
components that allow internal combustion engines and other propulsion systems
to operate on clean emission alternative fuels such as natural gas, propane,
ethanol, methanol and hydrogen used in fuel cells.

    Headquartered in Cerritos, California, the company orchestrates more than
400 dealers/ distributors and 14 corporate offices/facilities worldwide
including: United States, Australia, Japan and Mexico.  It operates in the
Netherlands, France, Germany and the United Kingdom as IMPCO-BERU
Technologies, B.V.

    IMPCO's common shares are listed on the Nasdaq under the trading symbol
"IMCO."

    Certain matters discussed in this press release contain forward-looking
information that involves risks and uncertainties that could cause actual
results to differ materially from current trends.  These include growth of the
alternative fuels market, OEM automotive product sales, competition, the
company's ability to design and market new fuel management products, the
company's ability to meet OEM specifications, and other such risks as cited in
the company's 1999 annual report on Form 10-K and other documents filed with
the Securities and Exchange Commission.
