Clean Diesel Technologies, Inc. supplying catalysts to Fisker for Karma; tackling the cold-start problem
Clean Diesel Technologies, Inc. (CDTI) is supplying emission aftertreatment catalysts utilizing its patented mixed phase catalyst (MPC) technology for the Karma, Fisker’s new plug-in gasoline-electric hybrid luxury sedan, which starts shipping to both European and US retailers this month. Clean Diesel commenced catalyst shipments to Fisker in the first quarter ended 31 March 2011.
This is a new developing market for Clean Diesel; we are proud that Fisker has chosen us as the exclusive catalyst supplier for the highly innovative Karma, a vehicle we believe will set new standards for environmental sustainability and accountability. Clean Diesel has long been active in the research and development of more cost-effective solutions for automotive catalytic converters as emission standards around the world continue to tighten. Through this ongoing process, our team has developed proprietary and patented catalyst technology for state-of-the-art gasoline engines that meet Fisker’s high performance standards.—Charles Call, Chief Executive Officer of Clean Diesel
Controlling tailpipe emissions from an engine in an extended range electric vehicle or plug-in hybrid can be challenging, Call noted, because of the potentially infrequent engine operation and increased number of cold starts. The aftertreatment solution for such an application requires catalyst engineering and modification of the engine control unit to achieve the requisite very low emissions.
CDTI is supplying its materials science expertise and Fisker is handling the ECU side, Call said. The CDTI solution keeps the nano-sized structure of the precious metal elements of the catalyst small, resisting agglomeration of the precious metal particles to keep the maximum surface area available.
Clean Diesel offers a range of fully-developed products to meet new, higher performance requirements at reduced precious metal levels. In addition, the design versatility of the MPC technology facilitates the sustainable use of precious resources while enabling customers to meet rapidly evolving emission control requirements, the company says.
