Mystery Diesel Model... Any Ideas?

[hopperwhistle]

Just got this scratch built hot bulb two cycle semi-diesel engine model. I think the builder was loosely copying a Mietz & Weiss engine, unless somebody knows of anything else he might have been copying. Anyone know enough about big hot bulb oilfield engines to say what all this still needs??

Anybody?

Hello can you send me the plans for the engine

 

[hopperwhistle]

I dont have the plans

I know nothing of these engines, so can’t help.
Right now it is just an objet d’art, I hope you get some feed back, as I would like to see any progress you can make.
Looks to have 9’ish inch flywheels, thx for including ruler for perspective.

Does it have a connecting rod and piston? Can you remove the cylinder head so we can see the combustion chamber? The main part that is missing is the fuel injection system, but as it is a hot bulb engine this should not be too difficult.

Does it have valve gear? As a 2 cycle engine I can't see the induction mechanism.... but assume the block nearest to the crankcase is an induction port (piston ported? - to the crankcase... If so it then needs transfer ports to the combustion chamber...

I think that the block on the back of the crankcase is the inlet valve (closed by a spring) and the transfer passage is on top of the cylinder block. The exhaust port is under the block.

Thanks, So have I got it right now?

Looks complete except for the fuel injector, pump, etc?

I am a little confused by the brass fitting on top. I guessed cooling water as the injector should spray into the hot bulb.
