In Denver, International Truck and Engine Corporation Strongly Supports EPA Proposal to Reduce Sulfur Content of Diesel Fuel

30 June 2000

International Green Diesel Technology is Based Upon Ultra-Low-Sulfur Fuel

 
    DENVER - International Truck and Engine Corporation today endorsed the 
Environmental Protection Agency's proposal to cut the sulfur content of diesel 
fuel, calling it "a prerequisite toward meeting the challenging new emissions 
standards beginning in 2007."

    Brian Whalen, International vice president for public affairs, testified
in support of the proposed new standards at an EPA hearing in Denver, the
company's fifth such hearing within two weeks.

    Whalen cited the role of ultra-clean-diesel fuel -- less than 15 parts per
million of sulfur content -- in addressing both particulate emissions and
emissions of oxides of nitrogen.

    "Progressive oil companies already are making 15 ppm diesel fuel
commercially available," Whalen noted.  "With this ultra-clean fuel available
so soon, International will commercialize its 'green diesel' engine technology
next year, and thus achieve EPA's proposed MY 2007 hydrocarbon and PM
emissions standards six years ahead of schedule."

    On May 16, International announced in Los Angeles that in summer 2001, the
company will introduce a production school bus that will be equipped with
International(R) Green Diesel Technology(TM), utilizing a catalyzed
particulate filter, and fueled with ultra-low-sulfur fuel.

    "International is investing hundreds of millions of dollars in the
development of new technologies for all the markets where our engines are
sold," Whalen said.  The company's technological breakthroughs, he said, will
allow it to achieve "unparalleled emissions reductions."

    International Green Diesel Technology was first introduced in June 1999,
with demonstrations that showed particulate emissions 50 percent lower than
the best compressed natural gas engine.  Hydrocarbons were reduced below
measurable levels, eliminating the odor often associated with diesel engines.
Overall, the technology reduced particulate emissions by more than 90 percent.

    International Green Diesel Technology is based on a history of
innovations.  In 1989, International demonstrated its smokeless diesel
technology, five years ahead of the EPA's mandated deadline.  In 1994,
International introduced its low-pressure common rail fuel-delivery system,
which provides a virtually smokeless exhaust, again setting an industry
benchmark for emissions technology.

    The need for ultra-low-sulfur fuel is similar to what occurred when lead
was forced out of gasoline because it was damaging the expensive anti-smog
catalytic converters that auto companies were required to install on new cars.
The removal of lead from gasoline began in 1975 and the phase-out was
completed by 1986.

    International Truck and Engine Corporation is the operating company of
Chicago-based Navistar International Corporation , which had 1999
sales and revenues of $8.6 billion.  International Truck and Engine is a
leading producer of medium trucks, school buses, heavy trucks, severe service
vehicles, mid-range diesel engines and parts and services sold under the
International(R) brand.  The company also is a private label designer and
manufacturer of diesel engines for the pickup truck, van and SUV markets.
Through its finance subsidiary, the company also provides financing and
liability insurance for its dealers and customers.
