Vance,

How about a Jumo 223 "box" motor?  An opposed piston two stroke diesel which
sort of joined  two engines with 4 cranks out on the corners.  The 224 was
an even
bigger version, 223 made 2500 hp, the 224 4500 hp. I can't find any hint of
an ignition system and the "valve covers" maybe actually crankshaft covers.
German, late WW2.   Not sure if it ever flew.  24 pistons but only 12 cylinders?
