ABSTRACT:
An external combustion engine wherein air compressed in a plurality of cylinders is delivered to a common combustion chamber is disclosed. The hot exhaust gases exiting the combustion chamber of the present invention are returned directly to the cylinders at a pressure which approximates the compressed air delivery pressure. In a preferred embodiment the combustion chamber is divided into two portions and control over the engine output power is achieved either by varying the time of opening of the valves which return the exhaust gases to the cylinders or by means of a variable pressure drop fuel delivery device which operates in combination with a variable delivery fuel pump.
