Yeah, I got one of those running the back-up generator at home.

dayum!!!!

Well, they can never be accused of penis envy when it comes to engine size!!

i couldnt afford to put fuel in it

I remember watching a segment on Discovery once about a ship being built with a similar, but perhaps larger engine. It was hard to believe. They could service it, while running, one cylinder at a time. They took the cylinder off-line and then a technician opened a hatch and entered the cylinder.

I am always amazed at the diversity of the Otto cycle engine. The same principle that runs an RC engine with a piston the size of your little fingernail or a Formula One engine at 19,000 RPM can run this monster. Often wonder what a 100+ years of development would have done for other forms of power (steam,electric,etc).

Wow, a 2 stroke deisel too. Does that mean some poor SOB gotta mix oild with deisel fuel in the little cans before pouring it into the tank?  Slab a turbo on that puppy!
Amazing engineering though.

 Unless I did something wrong, I calculate 4.2hp/litre  Although the engine is spinning at 102 rpm. I wonder what kind of hp you'd get at 8000 rpm? 

[grumburg]

How do you MACHINE something that big?

[cbjunkie]

haha - good question ...

answer? BIGGER MACHINES!! BWAHAHAHAHAHAHAHAHA!!! 

[needswork]

Yeah, you need a huge honkin' lath for those pistons! 

[Rocking-M]

for the pistons, what about the lathe for the crank

I've talked to guys that have done that on real large tugboats....no #$%*.

Dr Diesel would kick your ass if you called his engine an Otto.   For a thousand dollars.....What ever happened to Dr Diesel??

[Bob Wessner]

He committed suicide in 1913. You can send the check to......

The German's pushed him off the ship as he was  defecting to England.

they are called cathedral engines because of their height. to torque the head studs, the studs are stretched with a winch to a prescribed poundage then the nut is nipped up then the winch is released. You gotta love a motor you can climb on or walk around on a catwalk
