I saw this and thought I just had to share, check out the link

They either havent finished lightening the fly wheel or it was a bit out of balance

i was looking at that myself...
could be a timing thing, or some kind of built in game where you chuck oranges thru the holes while it's spinning... things can get boring in a ship's engine room after a few days.
if it's a ship...

:bounce

How do I make it fit into the Kombi?
I'd hate to see what happen's if she throws a rod.
Rob.......

You might have trouble getting 100,000HP to the ground in a kombi.

There's holes at the top, and then a big weight at the bottom. Not sure what it is.

The fact it gets over 50% efficiency is amazing. :o

Yea, 50% efficient motor, and 1% efficient drive through the prop!!
Great idea
Still amazing. Looks like a 1 piece crank too.

and here are the specs.
The Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine is the most powerful and most efficient prime-mover in the world today. The Aioi Works of Japan's Diesel United, Ltd built the first engines and is some of these pictures were taken.
It is available in 6 through 14 cylinder versions, all are inline engines. These engines were designed primarily for very large container ships. Ship owners like a single engine/single propeller design and the new generation of larger container ships needed a bigger engine to propel them.

The cylinder bore is just under 38" and the stroke is just over 98". Each cylinder displaces 111,143 cubic inches (1820 liters) and produces 7780 horsepower. Total displacement comes out to 1,556,002 cubic inches (25,480 liters) for the fourteen cylinder version.

Some facts on the 14 cylinder version:
Total engine weight: 2300 tons (The crankshaft alone weighs 300 tons.)
Length: 89 feet
Height: 44 feet
Maximum power: 108,920 hp at 102 rpm Yeah, baby!
Maximum torque: 5,608,312 lb/ft at 102rpm yes, that's 5 million lb/ft of torque!

Fuel consumption at maximum power is 0.278 lbs per hp per hour (Brake Specific Fuel Consumption). Fuel consumption at maximum economy is 0.260 lbs/hp/hour. At maximum economy the engine exceeds 50% thermal efficiency. That is, more than 50% of the energy in the fuel in converted to motion.
For comparison, most automotive and small aircraft engines have BSFC figures in the 0.40-0.60 lbs/hp/hr range and 25-30% thermal efficiency range.

Even at it's most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour
a man with big bearings means......?

and

All those details and more are on the webpage that the first link points to. Including info about a 14cyl version that they are planning on making.

I wonder what a 2 stroke that big sounds like?

u reacon u got some horsepower wes!!!!
cheers

I used to do some work on ship cranes and quite often had to use the engineering facilities usually in the engine room. Man some of those ships have machine shops on board you'd kill for.
