Jitender Dhillon: Its gonna be pain in the ass to work with all those tubes and wires
Brian Lillquist: it really has a nice sound at idle.
nmdiesel89: Yes DD15s have a turbine wheel that engages the flywheel through a gear box
when more power is needed. believe it adds about 50 hp if i remember
correctly. its called turbo compounding, been used since WWII on bombers.
basically its just a turbine housing with a gear box instead of a
CARL Barre: DETROIT MUCSLE
elcamionero38: Wish this was still a good old American Detroit diesel, but now they have
German Daimler fingerprints all over them. Hard to call them Detroit
anymore, more like Mercedes diesel.
j morgan: where is this located at I have worked on many dd15s and have never noticed
this turbine wheel
chechnya: What's the problem with fewer emissions?
MisterFlaherty: BTW I own a 2009 Cascadia with the DD15 and 472,643 miles on it. The only
problem I've had is a couple sensors go bad (warranty) and a rack and
pinion leak. With 3.55 gears I walk past most trucks on the road.
TheDieselpowers: thats a nice engine. im goin to nadc in july to work on big rigs. diesel
engines have come a long way they got ALOT of wires now a days.
AmoralEngineer: @detroitdiesel653 MTU in germany still produces 6v53T's, 8v71t's, and
8v92t's for the military. Other than that places will only reman old 2
turbosuperiority: That's one high-tech lookin some bitch. I recognize about half the stuff in
that engine bay.
trucker765: In Europe they have found ways to completely remove all emissions crap on
these engines and they are pushing 800+ hp
thatoneguyjosh: i shift between 1100-1300 rpm i have never gone beyond 1500 but it has
great power in my operating range
bj99ful: A far cry from the old 2 strokes. The new Detroits are ok but I still miss
the sound of the old 2 strokes; there aren't many still running where I
live. They're mostly just in the older transit buses and an occasional dump
truck. Hardly ever do I hear one travelling on the highway.
pfchubby: Not the greates motor to work on but its a step in the right direction for
bmw2go11: could you imagine the power those engines would produce if all the
emissions crap were to be removed?...
commiesarelame: Ugh. Love the Detroit, but can't stand all the emission BS on this engine.
Where's the engine anyways? At least with a Cummins ISX, you can see the
Juan Vuletich: Indeed. it's a complex system, I think similar to the MBE4000. I'm just a
student in diesel mechanics and we've seen some of these engines.
thatoneguyjosh: no its keeping it alive
tiktak25: Sounds like an old 3406 cat I had back in the early 90's
Bamchucknorris: @detroitdiesel653 nope
Jon-Erik Butcher: I am also a tech, 21 years old and been doing it for 2.5 years. the fleet i
work with has volvos with volvo engines, old FLD daycabs with 12,7 L Series
60s, both of our M11 blew up, one broke the crankshaft (yes...crankshaft,
the flywheel was wobbling but yet it was bolted still haha), and 2006/07
Columbia/Centuries with MBE 4000 and 14 L 60s, and Cascadias with DD15 and
ISX. the ISX is troublesome with the air compressor heads and they are
noisy, along with the DPF and #7 doser injector.
EasternAggie: Gear driven turbo? No such thing. Maybe a gear driver supercharger, but
even then I don't think it's on this engine.
Keith Roberts: Not really, 100% built in Detroit USA!
detroitdiesel653: sounds nice at idle i bet it sounds great going down the road
Luis Torres: sounds like crap, 60 series is the power!!!!
j morgan: sorry I know what your talking about now and yes your right its like 53
horse power its right above the starter but covered up by heat shields in
nmdiesel89: should be just below and behind the turbo charger, under a heat shield.
Keith Roberts: Its actually assembled and manufactured in Detroit along with New DD axles
in a 3,500,000 sq. ft. facility. All american!
tiktak25: I couldn't agree more!
thatoneguyjosh: im getting 8.5 mpg average in my cascadia what does your truck get?
jorpe64: Suena como un Perkins de 4 cilindros frio, HORRIBLE!!!!! Detroit Diesel
8V71 un motor de verdad!!! Detroit Diesel 8V71 a real engine.
MisterFlaherty: Dafuq are you talking about "gear driven turbo"? That is literally exactly
what a turbo is NOT. A turbo has a turbine and a compressor. It is
basically an air pump that is driven by the exhaust gases. Tech my ass...
Brian Lillquist: I am a Truck Technician and work on these everyday,and yes they are a
Mercedes design so they are not American at all. if you want a true
American Engine Buy a Cummins ISX.
tiktak25: You can always gauge how well a new engine design is doing without asking
tech that was trained and working for detroit or cat or any engine, because
they will always promote what they work on. Look around while your on the
road and take notice to what being pulled be hind the tow trucks and broken
down side of the road. I can tell you in 2011-2012 The Cascadia and Prostar
where along side the roads everywhere!! I suspect the ISX in the PS and
possibly this DD15 or DD13 in the Cas.
genc shkembi: SWEET ROARING
freighthog3511: There is to much crap attached to the sides of that engine! This emission
crap has ruined the trucking industry...
elcamionero38: Yes it is 100 % assembled in the US in Redford, Michigan, but it's design
engineering and components are not 100% American. The DD15 common rail fuel
injection is from Germany...Bosch , unlike the US Delphi unit injectors on
the 60 series, and various other components from Daimler's Mannheim and
Brazil foundries as well. Daimler designed this engine to be global
platform soon to appear in Mercedes trucks overseas, so it is not a true
blue American engine like the 60 series was.
MrJkbubbabutt: Ok, I've heard sewing machines that sound tougher.
ONLY1PEA: @freighthog3511 ABSOLUTELY RIGHT!!
nmdiesel89: its fine man lol i have been outta the industry for about 2 years now but
still like to try and keep up with the latest tech
Kevin Lynch: i heard this engine is only good for around 1200 - 1750 RPM, it loses a lot
of power after that, anyone have more knowledge on this? not that you'll be
revving a huge diesel
Jon-Erik Butcher: in the beginning, you see that big heat shield over the turbo? its hiding a
gear train. DD15 has a gear driven turbo that runs off the back cover. it
helps reduce turbo lag. i am a tech and the fleet i work for has over a
hundred of these things. they are nice, but they have a few oil leak
problems. the only way to change a turbo on one of these is with a crane
and im being serious. so far i dont know anyone who has had to change one
even at freightliner dealer near me.
detroitdiesel653: does detroit even make 2 strokes any more
trucking604: Same size as a 3406 Caterpillar, 15 liter also.
tiktak25: I have owned several 12.7 60 Series one 430 and the last a true 500hp and
although they won't pull with a cat they were hard to beat on mpg and it
was nothing to get a million miles out of both I had and was strong when I
sold them. I don't think Detroit will ever have another jewel like the 60
series..but then again that was before the Government and tree huggers got
involved and really caused havoc in the trucking industry forcing cat to go
its own way, and now these type of clutter boxes.
studpuppy69: Sounds nice. Looks expensive. What a headache to even thinking about
working on compared to a 2000 model year series 60!
kwpowerluva: From what I've heard these engines leak like a siv 200000 Kms and they're
wet from fan to g,box and they run high in temp bring back ddec4
