A really neat engine. No doubt, many of you have heard of it, but, I'm sure some have not.
2-stroke, 9 or 18 cylinders with 18 or 36 pistons arranged in a triangular, or, "delta" configuration, no cylinder head or valvetrain, 3 crankshafts, 1 of which turns the oppposite direction of the other 2...
Fantastic power-weight ratio compared to contemporary, conventional-design diesels and a lot more compact and approximately 1/5 the weight!
Designed in the 1950s for marine use. Also used in locomotives as well as in a one-off firefighting pump trailer rig for the NYFD!
