VENTURA, Calif., Dec. 19, 2013 (GLOBE NEWSWIRE) -- Clean Diesel Technologies, Inc. (Nasdaq:CDTI) ("CDTi"), a leader in advanced emissions control solutions, is pleased to announce that it has received two significant emission reduction product verifications from the U.S. Environmental Protection Agency (the "EPA") for use in heavy duty highway truck engines and off-road engines. The uniquely designed Purifilter®EGR, featuring CDTi's proprietary MPC® technology, is a passively-regenerating diesel particulate filter that provides exceptional filtration and regeneration efficiency for the removal of particulate matter. The EPA first verified Purifilter®EGR for 2002-2010 heavy duty highway truck engines in November 2012. In October 2013, the EPA extended the verification to cover all exhaust gas recirculation ("EGR") and non-EGR heavy duty highway engines certified with particulate matter emissions at or below 0.1 g/hp-hr manufactured between 1993 and 2010. This extension of the Purifilter®EGR verification means that it can now be applied to the vast majority of heavy duty highway engines sold over the past twenty years. In December 2013, the EPA verified Purifilter®OR for Tier 1 thru Tier 3 (1996 to 2012) off-road engines with power ratings from 100 to 603hp and certified with particulate matter emissions values of 0.2 g/hp-hr or less. The Purifilter®OR is the off-road version of Purifilter®EGR. The EPA has recently announced a $2 million funding for a 2013 construction equipment rebate program. In addition, the EPA has announced the availability of $4 million in DERA funding for clean diesel projects at ports. CDTi's Purifilter®EGR and Purifilter®OR may now be employed by fleets under these EPA funded programs in addition to CDTi's other EPA and Air Resources Board verified diesel emission reduction products. "With EPA verification granted, CDTi can assist highway and off-road fleet managers to broadly retrofit their vehicles with passively regenerating diesel particulate filters in order to reduce particulate matter emissions in excess of 90%. With our extensive retrofit experience and large distributor network, we are absolutely committed to addressing this larger market opportunity," said Ian MacDonald, Vice President, Sales & Marketing for CDTi.
