Here is a 4 cylinder inverse radial inboard. (I think it's an inboard). It has 4 pistons, 4 crankshafts, 2 carburetors, 1 spark plug. One of the carburetors has been removed, (this is known for sure) and a water pump and timer/mag are gone. some type of cover or shroud has been removed. See if you can figure it out. No idea who made it, but open to suggestions.

It looks like there is either a rotary or reed valves to the central combustion area. I would think the flange would be the exhaust. I would think it would be more inline with a horseless carrage engine. It is neat and unusual. |

WOW! Such a compact shape. geared way down . I wonder if that chain sprocket is original? Is the
crankcase aluminum? Looks like 4 lawn mower engines in size?? The Langley "Aerodrome" that might have flown before the Wrights in 1903 was powered by some kind of odd "radial" engine but I recall it was supposed to be 40 or so HP. The brass rods and straight cut gears make this LOOK like its early 1900's but....

If this engine is from the early 1900's, I wonder if it might be a Janus engine made in England in the 1905-1907 period. Janus exhibited a very odd motor at the 1905 London marine exhibition that used opposed piston configuration. The engine above does not seem to be a true opposed piston typebut it seems to be in the same alternative design ballpark. Is the carburetor British made. It doesn't look North American. |

That is realy intresting. I wonder how it works, is it a conventional 2 or 4 stroke, or somthing else ? It does not seem to use crankcase for mixture pumping. But it doesnot seem to have any valve mechanism at half crank speed for exhaust control.
If that flange is the exh. it looks like it may come from conventional 2 stroke ports on just two cylinders. |

If you look carefully at the cylinder casting you can see where some internal passages to ports go:
There seem to be conventional 2-stroke exhaust ports on just two cylinders. and all cylinders have normal 2-stroke induction and transfer ports, using crankcase pumping.
The picture inside does not show the transfer port because the con-rod is covering it. |

How is it timed? Do all pistons hit TDC together, two-and-two or all differently? It appears the combustion chamber is off center from the cylinders. Is there a supercharger of some sort or a rotary valve on the center shaft perhaps? I just spotted it and it really has me curious. |

Has anyone found out any more information about this engine? |
