V16 two stroke diesel

[jtanguay]

This is billed as the 'Largest Diesel Engine in the World'.  I don't know if it's true but it's pretty d@mn big.

Maximum power: 108,920 hp at 102 rpm  
Maximum torque: 5,608,312 lb/ft at 102rpm  

Even at its most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour.

 :shock:

5.6 million ft/lbs of torque is .... meh. Decent.


 :shock: Thanks for answering my question guys.
102 rpm... i can't imagine what that would sound like...

Can Giles set my pump for the same fueling as one of those?
I have so many questions about that engine I'm not even going to start.

yea good choice! you just stay focused on your own motor! all you need learn right now!

this thing makes 5149.02% more torque than HP...  :wink:

just one injector is bigger than our whole 1.6 motors... or even 1.9  :lol: and look at the size of the fuel lines... more like fire hose!!!  no wonder that thing drinks so much fuel  :lol:

[Smokey Eddy]

what on earth does that use for a pump???
Just the mechanics of the entire thing are so outrageous ....
must ... restrain! listen to blkboostedtruck!!!

hey Ed! i;m watching you! i can easily make a phone call and send someone over to straiten you out!
  :shock:
those motors are prolly found in freighter ships they might be efficient but do you know how long i could drive my caddy on one piston firing of fuel?
prolly 2 weeks?

I was fortunate enough to be raised in a family which had road construction and rock crushing putting bread on the table, as such I grew up around "the shop" where at any given time there would be a V8 or V12 diesel torn down and in peices. Turbos the size of my head, and pistons just as big. Intercoolers that take up the entire opening of the back of a transport container.
Our portable rock crushing set up is currently powered by a 4 stroke V12 Cat Gen set, new with common rail, and a beautiful turbo sitting on each bank, sound pretty mean at full load when your starting the spread up in the morning, but it will never sound as mean or as dirty as some of the old two strokers I remember from when I was really young.
Sorry about the rant I get a bit excited when I talk about diesels, I'm sure some of you can relate.

Let's actually figure it out. OK so IF 1,660 US gallons per hour to operate thats 6274.8 Litres per hour.
102rpm * 60 minutes  = 6120 revolutions an hour.

Therefore, 6274.8 Litres/hour / 6120 revolutions an hour is just over 1 Litre per revolution for all 14 cylinders (which is nuts) so thats about 75 ml per cylinder each time it goes *bang* IF IT WERE TO FIRE ON  EVERY CYLINDER ON EVERY REVOLUTION.

but it doesn't. It's a two stroke so every other stroke is a power stroke right?
so its more like 150ml per fire.

If my calculations are right  :wink:  ...........            Duane.

i wish i could store what that thing drinks in an hour in my back yard...   that is fuel for a few years at least...!

Two strokes fire every revolution.  :twisted:

Every rotation involves two piston strokes, one up and one down.

Therefore a two-stroke completes it's full cycle of operation (intake-compression-combustion-exhaust) within a single rotation of the crankshaft.

A four stroke must complete the same four phases (Intake, compression, combustion, exhaust), but it takes four "strokes" of the piston to do them, needing two crankshaft rotations.

[Smokey Eddy]

oh ok, so it is 75 per fire then.

er... wait no ...
someone correct me! I just got out of class and i want to go back to bed but i really want that to be right!!!

[rabbitman]

I bet you could throw a rabbit into the turbo and it'd chew it up and spit it out the exhaust! :shock: I think I heard these are for generators to power a city or two. I wonder how big of cloud they can make :lol: hahaha
I wish we could find out the compression ratio. Is that the starter in the lower left in the crank picture? Actually it prolly uses air pressure to start and then never gets shut off. Prolly has a external oil reservior so you could change it as it ran :shock: I wonder how much anti freeze it holds. hahaha. perdy crazy........I want one.

The diesel that I linked to is designed 'primarily for very large container ships'.

I know where there used to be a couple in old Euclids too.

I'm pretty sure the last 2 stroke Detroit Diesel we installed in a Euc was about 2000 in a 190 ton hauler.  They actually looked pretty much like the picture in the first thread on this post.  They went to Dexing in China.  Currently we're putting 15V4000 Detroit MTU's in our biggest trucks - derated to 2700 HP to help save fuel and extend service life.
