Engineering for 2010 and Beyond
Advanced Doesn’t Mean Complicated
Step inside our state-of-the-art facility to learn how the UAW and Detroit Diesel build the DD15™.
Billions of Miles of Innovation
With 70 years of reliable engines under our belt, we know what works and what doesn't. We took what we learned from our successes and failures to design our most reliable, fuel-efficient and powerful engine yet.
2010 Is Just Around the Bend
You're not just buying an engine today. You're looking for an engine for years to come. We designed the DD15™ as an engine that fleets can rely on for whatever comes next. Training investments you make in the DD15 will pay off when EPA 2010 regulations come in, and the DD15 will change only with the addition of the After-Treatment System.
The Knock on NOx
The thing about reducing NOx emissions in the past has always been the way it drains fuel mileage and/or power. With our new DD15, we've cut NOx emissions without the drain on fuel mileage or power. The “amplified” in ACRS means full injection pressure capability is achieved by amplifying engine fuel rail pressure internally in the injector. The engine's electronically-optimized fuel delivery actually changes the pressure, the timing and the spray for every injection, to every cylinder, every second the engine is performing. This creates incredibly effective combustion for each and every revolution. Not only does this maximize your performance within the cylinders, but reduces deposits like soot and carbon, resulting in fewer Aftertreatment Device (ATD) regenerations.
“It pulls good. Very, very little engine noise. Couldn't even hear the Jake Brake.”
— Mitchel Graus, Fleet Driver, 19 Years
Simplification
Since we didn't retrofit an old engine, we built the DD15 to work simply, to get the most out of every drop of fuel, and to do so with less maintenance and heavier workloads. We designed it from the ground up to make oil filters, and other things you have to replace regularly, above the frame rail, so they're within easy reach.
The Resurgence of Turbo Compounding
The fuel-stretching technology behind Turbo Compounding has been around since it powered the U.S. bombers deep into enemy territory. By recycling “waste heat” from the turbo, the DD15 turbo compounding system adds up to 50 “bonus” horsepower with zero extra fuel.
A Sound That's All Purr
The DD15 is unlike any other engine you've ever heard. Detroit Diesel's completely electronic injectors use a series of injections to reduce noise. Think of it like fireworks: several small ones go off pretty quietly compared to one really loud one. That refined technology makes the DD15 quieter in the cab and on the road. Because you want to feel the power, not hear the power for 10 hours a day.
