Detroit Diesel reveals 2010 SCR packages
ORLANDO – Picture a square metallic “box” that fits snugly under the passenger-side of a Class 8 truck cab, housing all the exhaust aftertreament components required to meet the 2010 emission standards – diesel oxidation catalyst (DOC), diesel particulate filter (DPF), and selective catalytic reduction (SCR) system. This is but one of the “BlueTec SCR” packaging solutions Detroit Diesel Corp. (DDC) is planning to deploy to meet the 2010 emission standards.
“This proprietary ‘one box’ configuration will be used by the majority of our customers,” said Elmar Boeckenhoff, senior vp of engineering & technology for Daimler Trucks North America (DTNA), DDC’s parent company, during a news conference here at the Technology & Maintenance Council’s annual meeting.
DDC’s “one box” combines dual compact DPF and DOC with a single DEF (diesel exhaust fluid) mixing tube and dual compact SCR catalysts into a single subsystem offering less weight, Boeckenhoff said. However, DDC also plans to offer a “two box” configuration that separates the SCR components from the DOC and DPF to fit the space limitations of certain trucking applications.
