Engineering for 2010 and Beyond
Advanced Doesn’t Mean Complicated

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. Everything we’ve ever done as a company has led to the development of
this engine. 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 Amplified Common Rail System
(ACRS), 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 of each high capacity
cylinder. This 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.”

Integration and Simplification
The DD15 is the only engine launched in recent history to use decades of
real-world reliability when redesigning from scratch. 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.
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 free horsepower
with zero extra fuel.
A Sound That’s All Purr
The DD15 is unlike any other engine you’ve ever heard. By using the Amplified
Common Rail System (ACRS), the stroke is a series of smaller combustions. 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.
