Abstract

A steam engine comprising a chamber having a first inlet valve (200, 312) and a second outlet valve (200, 314); a reciprocating piston moveable within the chamber; wherein at least one of the first inlet and second outlet valve is coupled to a computer controlled mechanism (704) operable to open and close the valve. A double beat valve for use with the stem engine of the invention and a method of optimising steam supply to the engine chamber are also provided.
