Clean Diesel Technologies has licensed its Wire Mesh Filter technology to Headway Machinery, the largest diesel engine exhaust company in China.


Stamford, Connecticut-based Clean Diesel Technologies has licensed its so-called 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 January 1, 2008.


Clean Diesel, in return, will receive an upfront licensing fee and royalties on all WMF units sold in China.


The catalysed 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 US Environmental Protection Agency’s Environmental Technology Verification protocol as able to reduce toxic particulates by up to 75 per cent, carbon monoxide by 60 per cent, hydrocarbons by 80 per cent, and NOx by 9 per cent.
