RE: Most powerful diesel engine
thats INSANE, i wonder if i got a leveling kit and a new tranny if ill be able to put that in my rig
whos nicky? is that a member here or someone we dont know?
ORIGINAL: Aero Ram
Nicky's been trying to buy this engine off me for years, think he wants to put it back in his dirtbike...

I've seen this before, but still is awesome. You gotta love ~8000hp, 400,600 ftlbs of torque per piston lol. I really like the shot of the crankshaft. It's used in those big 1000ft + container ships. Also interesting that it's actually more efficient than most small diesel engines.

RE: Most powerful diesel engine
it is worth noting that 0.26 lbs of fuel consumed for each hp run for an hour.
As close approximations
lets say ULSD weighs 7 lbs per gallon
and a 7000 lb Cummins Ram
needs about 70 hp to cruise at 70 mph
0.26 times 70 = 18.2 lbs of diesel burned
18.2 divided by 7 lbs/gallon = 2.6 gallons of diesel used
70 miles travelled divided by 2.6 gallons = 27 MPG
As a rough approximation
most 2006+ truck 4 cycle diesels
loaded with new pollution equipment
in today's over the road 18 wheel trucks are getting
more like 0.35 lbs fuel per horsepower-hour
This is worse than the 0.31 lbs/hp-hr those diesels were getting in the 1980s
Note that the big ship diesel is two cycle
which means it has roughly half the friction for each power cycle
as a four cycle diesel
Also note that the rpm appears to be low
but with the 98 inch stroke
if you calculate piston speed instead of rpm
the pistons are moving up and down at about the same speed
as your Cummins does
