Air engine ?s

[urbana]

get an actual air motor. there lighter an mor efficant. if you must use the 2 cycle engine you will have to re-adjust the vavles timing. what are you going to do for a tank? where will you put it?

[WOW!!]

You could use a impact hammer. They have 1000 ft/lbs and like 8000 RPMS. They are bolted together so you could get some longer bolts and mount it to some 1/4''plate.

i just saw a cutaway of a 2 stroke engine, and it seems like making it air-powered would be easier than one would think. simply remove the reed valve in the fuel/air mixture intake, and intsall a hammer valve where the spark plug would usually be.

only problem is the spark plug must be vertically oriented to the piston to allow this to work, and it would also require some clever plumbing, but this is quite do-able.
