The biggest motor I ever did see

[Joe Kelsch]

Last month my cousin, his 3 year old, my uncle and I went to Cool Spring, PA to the Power Museum (or Powertrain Museum, either or I'm not sure). It's mostly hit and miss stuff. About all of it is gas and oil well motors. But there on top of the hill, in a building made around it, was the biggest motor that may exist today. It only makes 600 hp (@100rpm), but imagine the torque. Here's some pics...

Here's the building...

A little closer. That's my uncle standing next to the flywheel. He's 6'1" for perspective.

Here's a little write up about it

Ive seen its twin. Like 10 times. It is impressive. Its all painted up nice and runs for a few hours a day. Coolest part is they pumped Natural gas, and ran natural gas. And they use 2 pistons in line and combust fuel on the up and down stroke. Fires on the back of the piston for the return stoke. Its not loud either.

Theres about 10 large stationary engines there. 3 sawmills, big construction area using a bunch of oil steam shovels, few hundred tractors, have 3 working steam engines, old buildings. Could go on and on.

Big Engine

Thanks for posting-great pics. Very interesting.

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 where 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

Maximum torque:
5,608,312 lb/ft at 102rpm

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

that's not too far from me. i think i've actually been thru Rollag a couple of times.
where are you located in "Western MN"?

1917, thats some pretty impressive technology for way back.

I live in Breckenridge but I spend some time in Elbow Lake. Uncle farms there so I go out there every now and then. Ive been through Henning. Rubys dinner has some pretty good burgers!
