Reply to above post, from Jim:
The major problem with the torpedoes were the fact that they would not go
"boom" when they got to the target, not the engines.

Yes, there were some engine problems, but they were reliable enough.

Torpedo engines and the Dynacam have very little in common with this
engine except that they fall in the general category of "barrel
engines". That's like saying the little 3-cylinder Anzani and the
mighty R4360 were the same because they were both "radials".

The Fairdiesel is an opposed piston, 2-stroke diesel. That puts it in
the category of the Fairbanks Morse OP diesels and the Junkers Jumo
205 aircraft engines. The Fairdiesel had the added advantage that the
intake and exhaust port timing and port duration can be non-
symmetrical and highly optimized. Also the piston travel at "TDC" can
be delayed while the fuel injection happens. The Fairdiesel is a
theoretical masterpiece.

The only question is the durability of the cam followers at some
specified torque. That will require some testing to prove.
