Meeting the Challenge
At Detroit Diesel, we met the challenge to reduce emissions head-on by putting
innovation to work. We invested in engineering, research and development to
ensure our compliance with EPA ‘07 guidelines. We've optimized our existing
Exhaust Gas Recirculation (EGR) system to meet the low NOx requirements, and
developed a powerful Aftertreatment System to reduce the soot and ash
particulate matter. And while we were at it, we made even more improvements to
our engines. You'd expect no less from a leader.
New Advanced Fuel System
The new fuel system, which adds to the performance and cleanliness of our
entire line of engines, includes high-pressure, dual solenoid injectors that
provide exact fuel metering and enable independent injection pressure control.
This system has multiple injection capability to maintain the performance and
fuel economy advantages you've come to expect from Detroit Diesel.
New Exhaust Aftertreatment System
Without a doubt, the biggest enhancement to the 2007 Series 60 and MBE 4000 is
the addition of an exhaust Aftertreatment System, which replaces the muffler
assembly. The system is made up of a Diesel Oxidation Catalyst (DOC) and a
Diesel Particulate Filter (DPF) that captures and burns off soot. This process
greatly reduces exhaust emissions and is precisely controlled by proven DDEC
electronics.
Optimized EGR
A small amount of exhaust gas is recirculated back into the intake manifold to
dilute the incoming air/fuel mixture. An innovative EGR cooler ensures that
temperatures stay in the range that helps reduce the formation of NOx gases.
The 2007 EGR system enhancements include a tube-and-shell EGR cooler that is
more durable and new placement of the EGR valve—we've moved it to the cool side
of the engine on the Series 60. This proven placement improves EGR reliability.
