Single Piston Air engine

Hi all,

need help/ advice in designing a single piston air engine, It is part of a mechanical engineering course I am currently studying,
the only parameters i was given are
- Single cylinder with vertically displaced piston with rotation of the input shaft on a horizontal axis
- free standing with an operating envelope of 300mm x 300mm x 300mm
- accommodate a nominal piston diameter of 20mm
- engine capacity of 6.0cc / 6000mm (cubed)
Any help would be greatly appreciated

Thanks in advance
