Oxnard, California – May 19, 2015-- Clean Diesel Technologies, Inc. (Nasdaq: CDTI) (“CDTi” or “the Company”), a leader in advanced emission control technology, announced it will participate at the 2015 JSAE Annual Congress on May 22^nd at the Pacifico Yokohama Conference Center in Pacifico Yokohama, Japan. CDTi will deliver a presentation titled “Copper Manganese Spinel Based Oxide for Next Generation Three-Way Catalysts”, outlining the underpinnings of the Spinel™ technology patents granted to the Company in 2014 – the promising new technology for which on-vehicle testing is currently being conducted.

The JSAE Annual Congress, sponsored by the Society of Automotive Engineers of Japan, Inc., is an annual technical conference widely attended by major original equipment manufacturers (OEMs) and suppliers from Japan, China, Korea and other parts of the world.

About Spinel

The Spinel platform is a family of proprietary materials using various base metals that replace costly platinum group metals (PGMs) and rare earth metals in coatings on standard catalytic converters. Spinel works across a wide range of engine and vehicle applications – both gasoline and diesel – and has the potential for significant cost savings for OEMs by dramatically reducing or eliminating expensive PGMs and rare earth metals. The technology promises to enable early, cost-effective compliance with stricter emissions standards in the U.S. and around the world and to mitigate OEM exposure to supply uncertainty and price volatility in the PGM and rare earth markets.

About CDTi

CDTi manufactures and distributes vehicle emissions control products that leverage its advanced materials technology. CDTi utilizes its proprietary patented Mixed Phase Catalyst (MPC®) technology and other related technologies to provide high-value sustainable solutions to reduce emissions, increase energy efficiency and lower the carbon intensity of on- and off-road combustion engine systems. Reflecting its continued focus on innovation, CDTi is developing and commercializing proprietary advanced low-platinum group metal (PGM) catalysts including synergized-PGM (SPGM™), as well as zero-PGM (ZPGM™) catalysts. CDTi is headquartered in Oxnard, California and has operations in the U.K., Canada, France, Japan and Sweden. For more information, please visit www.cdti.com.
