Infrastructure / Energy futureClean Diesel licenses WMF technology to China's Headway

Published 10 April 2008

The U.S. EPA gave Clean Diesel’s Wire Mesh Filter technology high marks, and China needs it: At the beginning of the year it signed up to the Euro IV PM emission standards for light and medium duty trucks; a clean diesel technology will allow it to meet the treaty’s standards

As the debate over alternative energy sources, well, heats up,
there are those who want to see whether there is something to be done about
improving old sources of energy. We thus note that Stamford,
Connecticut-based Clean Diesel Technologies has licensed its Wire Mesh Filter (WMF) particulate filter
technology to Headway Machinery, the largest commercial diesel engine exhaust
company in China. Headway plans to
develop the WMF technology further and to provide particulate matter emission
reduction systems to China-based truck manufacturers. The technology will
enable the Chinese company to bring its customers in line with the Euro IV PM
emission standards for light and medium duty trucks. China adopted the Euro IV
emissions standards on 1 January 2008. Clean Diesel, in
return, will receive an upfront licensing fee and royalties on all WMF units
sold in China.

The catalyzed WMF technology was initially developed by Mitsui and
PUREarth for use in conjunction with Clean Diesel Technology’s Platinum Plus fuel-borne
catalyst. In 2005 Clean Diesel Technology acquired the title to the patents and
other intellectual properties relating to the technology.

The system has been verified by Clean Diesel Technology under the
U.S. Environmental Protection Agency’s (EPA) Environmental
Technology Verification
protocol as able to reduce toxic particulates by up
to 75 percent, carbon monoxide by 60 percent, hydrocarbons by 80 percent, and
NOx by 9 percent.
