Hi shashyazhi, glad you're back.

You wrote, Even those who have a fairly intimate acquaintance with the conventional internal combustion engine are led astray by
the horsepower output from such an apparently small engine.

It is a pretty small engine. I think the OX2 was demonstrated at 170 lb ft torque at 1250 rpm. That is 40 hp and piston speed of ~2500.

Yes, the cam profile affects the speed at any point, and we are talking average speed, so can't we shape the cam to increase the early acceleration and reduce the peak speed? (The crankshaft engine piston follows simple harmonic motion with (relatively) slow initial acceleration and fast mid-stroke velocity.)

You wrote, Initially the OX2 engine befuddles the mechanically unsophisticated person. I agree. I do not understand the sketch that shows the transfer of the torque from the cam to the cam follower to the cruciform to the guide pins to the rotating container to the output shaft. I think, intuitively, the friction wear on such small bearings and sliding surfaces will be high. I read on the Yahoo board from a UofW student that the demo there was cancelled due to engine troubles regarding lubrication. How do you feel about wear?
