Internal Fire Museum of Power

Recently I had an email from a gent in Australia who was trying to ID an engine that is in his fathers possession .
I have not got a clue so I said I would post it on the two forums that I use and maybe get a bit of help for him

Any chance somebody knows what it is ?













A little info that was supplied

· Engine Rotation: counter clockwise
· Bore: 4 .5 inches. Stroke 4 .75inches?
· Twin camshafts.
· Side Valve
· Roller cam followers
· External Oil system? total loss( this is missing from engine)
· Duel Ignition: ? Magneto +?
· Cone clutch
· No manufacture marking or stamps on the engine
· Big ends have 4 bolts on each, which go through the rods and threaded into the rod caps with lock nuts.
· Rods made from? Bronze like material and has no big end bearing, runs in the rod material.
· Crankshaft mounted in the sump.

Dual ignition would suggest aircraft, I think,and the water jacketing looks lightweight,too. Reminds me a bit of the Liberty V12 in "Babs",the old LandSpeed record car at Pendine.
Just my random thoughts.

Hi everyone,
I seem to remember a similar engine on display at the fleet air arm museum, it was from a german airship, I believe.

An early Maybach then ?

It looks a bit heavily built for a flying machine. My first thought was it was an early "supercar" engine. And most of those were of German origin.

I like the idea of cranking it over with that starting handle. A job for chauffeur !

Yes I was thinking its a bit on the weighty side for aviation with that honking great flywheel! I would think possibly very early commercial vehicle. Some of those omnibus engines were works of art.

What price a racing power boat engine? The exhaust stubs look just about right and a big flywheel is necessary with a small high speed propeller. Dual ignition would be a seamanlike precaution in such an environment.

I don't know, but what a beutiful piece of engine to grace any collection,
