DETROIT, March 12 /PRNewswire/ -- Detroit Diesel Corporation (DDC) will
use exhaust gas recirculation (EGR) and diesel particulate filters on its
heavy-duty engines to meet the EPA's 2007 emission requirements. This
decision was reached after months of evaluation of all available technologies.
EGR will be used on the DDC Series 60 and the Mercedes-Benz engines marketed
by the company. A new heavy-duty engine being developed by DDC and parent
company DaimlerChrysler, scheduled for release in 2007, will also employ EGR
and diesel particulate filters for North American applications.
"Detroit Diesel Corporation supports the goal of reduced emissions for
heavy-duty trucks and intends to deliver engines that meet the 2007
regulations while providing the greatest possible overall performance and
benefits for our customers," said Carsten Reinhardt, President and CEO of
Detroit Diesel Corporation.
DDC has extensive experience with EGR. The company has built over 40,000
Series 60 engines with EGR, and the 2004 Mercedes-Benz engines are also
equipped with EGR. These engines have performed well in their estimated
2.5 billion miles of service since October 2002. Detroit Diesel also has
utilized EGR technology in bus engines since 2000. By 2007, there will be
approximately 300,000 Detroit Diesel and Mercedes-Benz engines operating in
North America utilizing EGR technology.
"EGR is a technology that is very well known to us and increasingly
familiar to our North American heavy- and medium-duty truck customers,"
Reinhardt said.
EGR works by circulating cooled exhaust gas back into the engine air
intake. This lowers combustion temperature and reduces the formation of NOx.
The 2007 EPA requirements call for more than a 50 percent reduction in NOx
emissions and a 90 percent reduction in particulate matter. Detroit Diesel
will use advanced EGR technology to achieve the required NOx reductions in
2007. DDC and all other manufacturers will use diesel particulate filters to
meet the new PM standard.
Reinhardt said 2007 EGR engines are already in development, and the
company intends to operate vehicles with the 2007 engines by the end of this
year.
DDC chose EGR after an intense study of all available emissions reduction
technologies. "As part of the largest commercial vehicle manufacturer in the
world, Detroit Diesel was in a position to choose from a range of
technologies, including selective catalytic reduction (SCR)," Reinhardt
explained. "While we believe SCR is a viable alternative for 2010, we
ultimately selected EGR for 2007 because of the system's greater familiarity
with our customers and its ease of deployment."
Detroit Diesel Corporation, headquartered in Detroit, Michigan, is engaged
in the design, manufacture, sale and service of heavy-duty diesel and
