— Detroit Diesel Corporation (DDC) announced on March 31 that its Series 60(R), MBE 900 and MBE 4000 engines are poised to meet the stringent standards set by the Environmental Protection Agency (EPA) for 2007 diesel exhaust emissions. EPA emission standards require that commercial heavy-duty diesel engines comply with a Nitrogen Oxide (NOx) and particulate matter level that is nearly 55 percent lower than today's standard for NOx emissions, and 90 percent lower than today's standard for particulate matter.The company plans on further advancing its EGR technology, in addition to integrating a diesel particulate filter and a closed crankcase breather system to meet the emerging standards. In addition to an updated EGR system, the company will include a maintenance-free closed crankcase breather system, and an improved turbo charger system. In a media briefing held in late February, Detroit Diesel outlined its testing program that supports the updating of its three engines – the Series 60, Mercedes-Benz MBE 4000 and Mercedes-Benz MBE 900. According to Tim Tindall, director of emission projects for Detroit Diesel, the extensive testing program for the three engines will accumulate more than 25 million test miles for its current product and will provide valuable feedback to the engineering and program team through which adjustments will be made to ensure the highest quality products are offered in 2007.Detroit Diesel will soon deliver the first in a series of more than 75 trucks with 2007 Series 60 engines to its strategic customers who are supporting the company in its development of the 2007 engines.The Series 60, MBE 900 and MBE 4000 engines are available in vehicles produced by business units of Freightliner LLC. Freightliner LLC manufactures heavy-duty trucks in North America and is also a manufacturer of medium-duty and specialized, commercial vehicles.
