A Brief Summary of Why
Detroit Diesel is
Confident in SCR
How Does SCR Improve Reliability and Life Cycle Cost?
By utilizing SCR technology to reduce NOx emissions, Detroit Diesel engines will be able to reduce some of their dependence on EGR. Detroit Diesel engines will be able to function and breathe much more freely and efficiently without exceeding NOx emission levels. Less EGR means less heat and greater component reliability in today's more aerodynamic, tightly-packed chassis configurations. These factors should reduce fan on-time and its related fuel consumption, cycle wear, and noise. SCR should also have no adverse affect on engine oil drain intervals and soot levels. The SCR advantage will pay benefits to our customers during the entire lifecycle of their truck with fuel savings and reduced maintenance costs.

One gallon of DEF is used about every 300 miles. A typical Class 8 truck in North America will have a 20-gallon DEF tank, allowing approximately 6,000 miles between DEF fill-ups.
How Will My Truck and Fleet Operation Change With SCR?
Trucks equipped with SCR technology will have separate DEF tanks and injection systems that will be monitored with the EPA's future mandated On-Board Diagnostics (OBD). The primary responsibility of the driver and fleet operator will be to maintain adequate levels of DEF in the tank. The rest is up to the truck's control systems. Since the DEF will be consumed at a rate of about 2% of the fuel consumption, these DEF tanks can be fairly compact and still allow long ranges between fill-ups. DEF is available from several suppliers who are gearing up their infrastructure and distribution network to meet the growing demand. There will be plenty of choices available for our customers by 2010, whether they desire packaged or bulk DEF.
