Went to the Diesel House museum to just SEE the mahoosive engine that
wasn't due to run today but it turned out that a private party had booked a
start-up.

It's an 8 cylinder supercharged 2-stroke double acting engine with sleeve
valves above and below the piston. The engine design fell out of favour due
to problems with the lower valve/conrod seals. This was evident by the
smoke emanating from one cylinder. I think 5 minutes of running time was
plenty under the circumstances.

22,500 hp output. Don't know if it appears in the video but the generator
just looks like a large enclosed flywheel at the end of the engine. Hard to
believe that it can absorb all that power.

Apologies for FB link but having upload problems. I've made it public so it
should be viewable by anyone.

That was great Tim, thanks. I think it's seeing the piston tops bobbing
up and down at the very top that makes it interesting. It's an 'open'
engine where you can see what is going on, unlike a car engine.

Bet you're glad you got to see it running while you were in C'hagen.

Those are the crossheads not the pistons.
The layout is similar to a steam engine with these big two stroke diesel engines.

I wonder how much you have to pay to work there?

Those are the tops of the inlet valves that you see on top. Not sure of the
correct term, maybe sleeve valves. They're big plugs that unmask inlet
ports in the head as they rise and fall.

Yep, sleeve valves.

Not really the same. A sleeve valve is generally a "sleeve" around the
piston/barrel that rises, falls or rotates to open ports in the cylinder
wall.

These ones are like big pistons in their own right that rise and fall to
expose ports in the cylinder head.

More like normal porting on a two-smoke, then?

?? Not just simple OHV then?

In my day that would have been a side port valve

The jpg is pretty self explanatory. Yes it uses piston ports but it has one
"thrust" piston and two "valve" pistons (for the double action).
