Aspin Rotary Valve Engine

Live Aspin Number 1

New 500cc Aspin engine ready to test, will occur during November 2002. Pictures below
Not quite the success we hoped in that we did not get it running, but we did verify that the sparks were in the right place and sorted out a couple of mechanical problems concerning gear linkage and such like. The motor was trying to fire and the exhaust was getting warm but it did not burst into life. Shame. No matter, success is expected with session two after Christmas.

The project has had a chequered history since and for a while I was not allowed to work on the engine as it was protected by patents. It seems that I may be allowd to proceed in 2009, albeit after some delay.
