Clean Diesel Technologies' Platinum Plus Fuel Additive Receives Taipei Transportation Ministry Certification

    STAMFORD, Conn.--July 2, 1998--Clean Diesel Technologies Inc. (EBB:CDTI) Thursday announced that its Platinum Plus(R) bimetallic diesel fuel additive has earned certification from the Taipei, Taiwan Transportation Ministry for use with catalyzed soot filters supplied by Columbus, Ind.-based CleanPOWER Technologies Corp. and Hon Kai Industry of Taipei.
    The system is designed to reduce emissions on city buses under the Taiwan bus retrofit program overseen by the Ministry.
    "The additive/filter system effectively reduced smoke emissions during certification tests on three city buses while in commercial operation," stated Dr. Benjamin Yen, manager of CleanPOWER Technologies.
    The Taiwan EPA has announced a program that will provide fleet owners with financial assistance for using the certified emission reduction technology. CDT and CleanPOWER Technologies anticipate expanding the program to several additional Taiwanese bus fleets later this year.
    Earlier this week, CDT announced that it had been granted a broad-base patent for its innovation in the use of platinum group metals as additives to gasoline or diesel fuel. The additives improve the performance of diesel particulate filters or catalytic converters for gasoline-powered vehicles.
    "The Taiwan bus certification program represents one of the first commercial field applications of our advanced bimetallic fuel catalyst technology," said James M. Valentine, chief operating officer of CDT. "We're convinced our bimetallic additive offers good near- and long-term revenue opportunities based on the growing worldwide concern about diesel particulate emissions from new and existing vehicles."
    Valentine said the company's platinum fuel additives are already in European commercial applications for improving and rejuvenating aged catalytic converters and commercial interest is growing worldwide in the use of bimetallic platinum-based fuel additive technology for diesel particulate filters and oxidation catalysts.
    Clean Diesel Technologies is a development-stage company with patent-protected products that reduce emissions from diesel engines while simultaneously improving fuel economy and power. R&D efforts and products are grouped into two categories: Platinum Fuel Catalysts and NOx Reduction Systems. Platinum Plus is a registered trademark of Clean Diesel Technologies.
