Good stuff.....

Here's a slew of those radial Nordbergs (80 of them) powering the smelters at an old Kaiser Aluminum plant.

Thanks Backwoods Boggie. A quick google search brought some more pics. Very cool

Nordberg vertical shaft Radial Diesel....very cool. 1875hp.





220 of these!
Man...the main crew that would be needed to maintain them. I'd like to
see the size of the fuel lines coming into the building and the fuel
storage outside. Yikes!




Another Nordberg Diesel.




More Nordberg engines....Look at the people standing up on top.

(no words to express the wow factor)

I had never seen an opposed-piston engine before. I had to look it up and was surprised to see it was a common US Navy submarine power plant. Learn somethin' new every day.

This one has a pretty cool history too! (Google "honda nr) I'm putting this one in my next winter's reading...

Worlds largest diesel.

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.

Check out this double acting diesel in Copenhagen. It was/is used for power generation. Double acting engines are pretty wild, it utilizes combustion chambers both on top and under the piston so it generates power on both the up stroke and the down stroke.

This is a great video, shows the start up and running of the engine.

Very Cool!

Worlds largest working steam engine...

3000hp.

The complexity of these early steam engines were mind blowing. The
valve trains and maintaining timing took highly specialized skills.

Sooooo Cool!

On the other side of the size spectrum, is the venerable Wankle rotary engine



It went in several different vehicles, but the most recent is one of these;


That is a 2005 RX8 Shinka, Special Edition. There were only 1356 of those imported into the US in the one year of production of that vehicle. I had #989 I think. I LOVED that car, but had some financial issues and sold it. Of course, a couple months later, everything was good, but the car was already gone so... move on. Man I miss that car!!!

ya those are way cool engines !! size does matter. LOL now flyin ''w'' an his wankle, ha i had a wankle motor in a early 70's arctic cat snowmobile, what a piece a shit!!! now if you want to see a cool engine take a look at my 1948 ford 59ab highly modified flathead ford v8. it has alum. heads, alum. intake, duel chrome plated stronberg ''97'' carbs, a iskadarian cam. stock they were 100 hp, mine makes about a whoppin 150.[just 50 more than my 990 LOL.] in it's day she was one of the fastest around, now it just comes out for parades an car shows.

it's a check valve that holds 10lbs residiule pressure. the master cylinder is off of a ford ranger, which has disc brakes. the brakes on the hot rod are about 1940 which are drum. the return spring for the shoes will calapse the wheel cylinders enough that it returns almost all of the fliud to the resivour, which causes a very spungy pedel, unless the shoes are adjuster up very tight. disc brakes only require about 2 lbs residule pressure. if i had known all of this before i hand polished the master cylinder and made all new lines, and spent countless hours trying to get the brakes bled i would have just probably bought a kit that bolted right on in about 10 minites LOL. but theres just something about doin things the extra hard and expensive way that gives a guy real satisfaction when ya finally get it right!

Thumper with a capital T.
