PORTLAND, OR – Freightliner LLC has initiated the build of EPA 2007 emissions-certified heavy-duty Detroit Diesel Series 60 engines. Series 60 engines compliant with the new regulations emit 95-percent less particulate matter and 50-percent less nitrogen oxide than comparable engines in 2006. Freightliner LLC has made a significant investment in the technology’s innovation in its Detroit Diesel engines, including extensive validation with laboratory and field testing. Since the inception of the development program in 2004, Series 60 engines that are EPA ’07 compliant have accumulated over 14 million equivalent miles, with 2.5 million of those miles in actual customer vehicles executing revenue service. The engine and aftertreatment technology developed for Detroit Diesel engines in conjunction with the newer 15 ppm ultra-low sulfur diesel (ULSD) fuel spearheaded by the U.S. EPA, provides reduced diesel emissions. Effective Dec. 29, 2006, Freightliner LLC’s Detroit Diesel plant in Redford, Mich., began building engines for some of Freightliner’s largest customers. These first 2007 emission-certified engines will be installed in vehicles at Freightliner’s Cleveland, N.C.; Portland, Ore.; and St. Thomas, Ont., truck plants beginning Jan. 8, with initial customer deliveries planned before the end of January.
