<p>An engine (1) having a fixed portion (2) and a separate cylinder block (3) that is retained by the fixed portion (2) so that it can rotate relative to it. The cylinder block (3) is a rotor that defines at least one bore (4) in which a piston (5) can reciprocate, wherein the piston's (5) reciprocating motion is converted into a circular motion that assists in rotating the cylinder block (3) relative to the fixed portion (2) to provide a work output.</p> |
