Clean Diesel Technologies granted new patent

Posted By on November 5, 2014

Diesel exhaust treatment technology has vastly improved diesel engine emissions over the past decade along with ULSD fuels, but the technology is costly primarily due to rare earth metals. According to a press release yesterday, Clean Diesel Technologies, Inc $CDTI announced new proprietary Spinel™ technology will replace the use of platinum type metals in catalytic products.

This is CDTi’s first public announcement regarding Spinel technology, the development of which has been kept confidential until now.
