CDTi Outlines Development of Spinel(TM) Technology Platform at SAE 2015 World Congress and Exhibition

OXNARD, Calif., April 22, 2015 (GLOBE NEWSWIRE) -- Clean Diesel Technologies, Inc. (Nasdaq:CDTI) ("CDTi" or "the Company"), a leader in advanced emission control technology, will participate in the SAE 2015 World Congress today in Detroit, Michigan where Chief Technology Officer, Stephen Golden, Ph.D., will deliver a presentation titled "Novel Mixed Metal Oxide Structure for Next Generation Three-Way Catalysts (TWCs)."

Dr. Golden's presentation will outline the fundamentals of Spinel™, a proprietary clean emissions exhaust technology that promises to dramatically reduce the cost of attaining more stringent clean air requirements. Vehicle testing of this technology is ongoing at independent certified testing facilities and involves a variety of original equipment manufacturer (OEM) engines. The Company expects initial test results by mid-year.

The presentation along with a white paper published by SAE International can be accessed via the Company's website at http://www.cdti.com/spinel.

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.
