Cleaner. Leaner. Meaner.
When you hit the road with a Detroit Diesel DD15, you're driving the first engine designed with integrated EPA 2007 technologies, and that is 2010-ready. And best of all, it meets EPA 2007 without the traditional trade-offs between lower emissions and worse fuel economy and power.
EPA 2007 Emissions
“We’ve cut emissions without the drain on fuel mileage or power.”
Amplified Common Rail System
The trick to reducing emissions in the past has always been the way it drains fuel mileage and/or power. With the Amplified Common Rail System (ACRS) used in the new DD15, we've cut NOx emissions without the drain on fuel mileage or power. The "amplified" in ACRS means that peak pressure is reached only at each point of injection, maximizing the combustion potential. This electronically-optimized fuel delivery actually perfects the pressure, the timing and the spray for every injection, to every cylinder, every second the engine is performing. This also reduces deposits like soot and carbon, resulting in fewer Aftertreatment Device (ATD) regenerations.
New Advanced Fuel System
The high performance fuel system for the Series 60, MBE 4000 and MBE 900 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 expect from Detroit Diesel.
New Exhaust Aftertreatment System
The EGR cooler dilutes the air/fuel mixture with cooler exhaust gas, which helps reduce the formation of NOx.
The Diesel Oxidation Catalyst burns off exhaust to create soot.
Burned off soot is trapped in the Diesel Particulate Filter.
Tailpipe emissions meet EPA 2007 requirements.
Without a doubt, the biggest upgrade 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.
To improve reliability and durability on the Series 60, the EGR sits the cool side of the engine. We also use a tube-and-shell EGR cooler that is more durable.
