Johnson Matthey First to Receive EPA and ARB Verification for Its Award-Winning CRT(R) Particulate Filter

    MALVERN, Pa., Aug. 30 Diesel pollution from trucks and
buses on U.S. highways and roads is a problem recognized by everyone.  There's
also worldwide recognition that Johnson Matthey's Continuously Regenerating
Technology, or CRT(R) Particulate Filter, is a highly-effective solution for
controlling diesel emissions... and now there is EPA and ARB verification to
prove it.  The winner of the Royal Academy of Engineering MacRobert Award,
Britain's most prestigious award for engineering innovation and societal
benefit, Johnson Matthey's CRT Particulate Filter was verified by the EPA on
November 16, 2000 and was the first filter verified for the EPA's Voluntary
Retrofit Program.  The EPA verification is applicable to all two- and four-
stroke on-road engines.  And now, the CRT filter has been verified by the
California Air Resources Board (ARB).  One of the first filters to receive
verification from ARB for use in its mandatory diesel risk reduction program,
the CRT filter is currently verified for DDC Series 50 and 60 engines.  With
an expanding market for filter retrofits on all types of engines, Johnson
Matthey is aggressively securing verification for all other diesel engine
makes and models.
    Leading the market in the reduction of emissions, the CRT filter removes
virtually all of the particulate matter (PM) from a wide range of diesel
engines.  In fact, through the patented combination of a platinum-based pre-
catalyst and a filter element, the CRT filter reduces PM, as well as CO and HC
(including toxics), by more than 90% and continues to do so for hundreds of
thousands of miles, proving itself to be the most durable filter available.
With more than 20,000 CRT filters in use worldwide having accumulated more
than a billion miles of service, the CRT filter is the most widely-used filter
for controlling particulate matter from heavy-duty diesel engines.
    And now with EPA and ARB approval, Johnson Matthey is rapidly extending
the use of the CRT filter into the many commercial industries that use diesel
engines.  Through demonstration programs in various locations, California,
Oregon, Washington, NY, Massachusetts and Washington, DC to name a few,
Johnson Matthey continues to demonstrate the CRT filter's unique ability to
consistently reduce emissions across a broad range of engines and applications
and do so with outstanding durability.  And once demonstrated, the proven --
and exceptional -- performance of the CRT filter makes Johnson Matthey the
natural choice for diesel emission control.
    One example is MTA NYC Transit.  Johnson Matthey successfully demonstrated
the capabilities of the CRT filter (see SAE paper 2001-01-0511 for details),
and helped MTA NYCT to develop a compelling story to enable them to retrofit
their entire bus fleet with particulate filters and ULSD fuel.  And with
Johnson Matthey's commitment to customer service and competitive pricing,
Johnson Matthey has become the prime supplier of filter technology to MTA
NYCT, the country's largest public transit fleet.
    Not content to rest on its past achievements, Johnson Matthey is
continuing its development efforts for extending the capabilities of its CRT
filter to a broader range of engines and applications as well as combining it
with NOx reduction technologies for a world class 4-way emission control
device.  In cooperation with various OE engine manufacturers, the CRT filter
is well positioned for both retrofit applications and the 2007 HDD PM
standard.
    Traded on the London Stock Exchange, Johnson Matthey is a 184 year old,
highly diversified global technology firm with sales in excess of $6 billion.
As part of Johnson Matthey's Catalytic Systems Division, the world's largest
supplier of catalysts for the automotive industry, the Diesel Emission Control
Systems group has been providing cost effective catalytic solutions for the
worldwide light- and heavy-duty diesel markets for over 20 years.
