A Brief Summary of Why

Detroit Diesel is

Confident in SCR

The New DD15 Designed with SCR In Mind

Detroit Diesel was able to design the all-new DD15, as well as the entire family of HDEP engines that will eventually replace both the Series 60 and the MBE4000 by 2010, to easily and efficiently accommodate similar SCR technology. The DD15 already utilizes an Amplified Pressure Common Rail Fuel System (ACRS), which provides some of the highest injection pressures and optimal combustion characteristics known to the industry. All of this technology and hardware will be highly proven by customers' real-world experiences well in advance of 2010.

There are over 100,000 SCR-equipped heavy trucks with Daimler engines in operation today. Having the advantage of being a member of the world's largest commercial vehicle and diesel engine manufacturer affords Detroit Diesel the enviable position of capitalizing on

something our European partners have already

perfected, in a way that is economical and reliable for

our North American customers. Detroit Diesel's adoption of SCR for 2010 will eliminate the need for our customers to experience significant changes in engine performance, durability, and economy due to the new regulations.
