A Brief Summary of Why

Detroit Diesel is

Confident in SCR

How Does SCR Help Improve Fuel Economy?

Simple. SCR will allow Detroit Diesel to focus its 2010 NOx reduction efforts on the exhaust gas after it has traveled downstream of the particulate filter. This allows Detroit Diesel to improve and optimize the performance efficiency of the engine under the hood by actually reversing some of its operational parameters, including NOx levels emitted before the aftertreatment device. Detroit Diesel's 2010 engines will actually have better fuel economy than their EPA 2007 compliant predecessors! This is a remarkable benefit that our customers can take to the bank every time they fill their fuel tanks.
