Labor Coalition Claims California E-Waste Bill Falls Short on Producer
Responsibility
Stamford, CT— Clean Diesel Technologies Inc. (CDT)
has received notification from the U.S. Environmental Protection Agency
of verification of emissions reduction performance of its Platinum Plus(R)
Purifier System for retrofit to 1988-1993 diesel engines. Engine dynamometer
testing of the Platinum Plus Purifier System after 1,000 hours of commercial
service shows that the system more than doubles the particulate matter
(PM) reduction offered by traditional diesel oxidation catalysts (DOCs)
currently in use, without increasing nitrogen dioxide (NO2) emissions.
Reductions of 40-50 percent in particulate matter emissions
were measured at Southwest Research Institute on a 1991 certified Cummins
medium heavy-duty diesel engine typical of those used in school buses,
municipal buses, delivery trucks and refuse haulers. The EPA, under its
Environmental Technology Verification test protocol, verified these reductions.
This high level of particulate matter reduction was achieved from use
of the Platinum Plus fuel-borne catalyst (FBC) and a low-cost, specially
catalyzed DOC used with commercial No. 2D fuel and also with ultra-low
sulfur diesel (ULSD) fuel. Verification of the Platinum Plus Purifier
System is posted on the EPA website.
Verification followed field trials with beverage delivery
trucks used in commercial service in Texas as well as with refuse trucks
in California. In these programs, the combination of Platinum Plus FBC
and DOC purifier system was demonstrated effective even in aggressive
stop-and-go delivery service. Reductions of 41 percent were verified for
application with normal No. 2D fuel and up to 50% with ULSD.
Commenting on the verification, James Valentine, Clean
Diesel Technology president and chief operating officer, said: “Most
other traditional DOCs give only 20-25 percent particulate matter reduction
and can cause large increases in NO2 emissions, which, as a strong ground-level
lung irritant, are restricted by the California Air Resources Board and
the Mining Safety Health Administration. In comparison with traditional,
heavily catalyzed devices, the Platinum Plus Purifier System uses only
a fraction of the precious metals, by putting the catalyst in the fuel
as well as on the lightly catalyzed DOC device. This dual-action approach
reduces more particulate matter at lower costs without any increase in
NO2 emissions. In fact, NO2 emissions are lowered with the system by up
to 40 percent.”
“With the Platinum Plus Purifier System, fleets
can start tomorrow with fuel currently in use and get 40 percent particulate
matter reduction, knowing that reductions will improve to as much as 50
percent when they switch to ULSD as it becomes economically available.
In addition, over a dozen fleet trials have confirmed an average of eight
percent fuel economy improvement from regular use of the FBC, which more
than pays for the FBC and helps offset the cost of the lightly catalyzed
DOC.”
The system should be especially attractive to local delivery
fleets and school buses with older, dirtier engines. Typical retrofit
capital costs for the Platinum Plus Purifier System could allow as many
as five school buses to be retrofitted, versus one vehicle retrofitted
for the same cost with a traditional, heavily catalyzed particulate filter.
Clean Diesel Technologies intends to supply verified
systems directly to end-users and through a planned network of licensed
distributors. The Platinum Plus FBC can be delivered pre-blended in fuel
by licensed fuel suppliers, or added to fuel on-site by end-users using
automatic dosing systems. Several on-board dosing systems are also under
development.
