Heh! I don't see it as myself having eaten my foot. I was merely going by
what was available on that page. You can't deny that, on the face of it, the
wheelnut guys were being confusing to say the least?
Strange that it doesn't use the crankcase in the usual two-stroke way.
That's always been one of the big advantages of two-strokes, "free"
supercharging. I remeber (vaguely) that, back in the 50s (?) a European (?)
motorcycle manufacturer made a two cylinder two-stroke with both cylinders
firing at the same time and a dummy cylinder (at 90 degrees to the main two
IIRC), the sole purpose of which was to increase the supercharging effect.
Just followed your link. Man, that's an interesting engine. 102rpm? Heh,
must be the slowest revving two-stroke in the world as well. It's also
*extremely* 'under-square', almost a contradiction from what one would
expect from a two-stroke but right for the speed.
Thanks for the correction and the link. I remember seeing a massive 12 (?)
cylinder diesel engine at Meremere/Kopuku. It used to be used to run the
aerial bucket-line that delivered coal form the mine to the power plant.
About 8 - 10 miles maybe. I wonder what happened to that thing and what type
of engine it was. I don't think it was one of these, although you never
know.
