Duke engines

Now this is a weird engine design...

I don't see a provision for a nitrous nozzle

Very interesting variation of the axial piston-engine.

Three power-strokes per revolution (same as a conventional 6), 14:1 compression on 91 octane, 20% more torque than a conventional engine of the same displacement - and less weight? The "bottle" seems to be built-in.

Interesting design.
