the invention proposes an engine supplied with compressed air comprising a main drive piston (1) driving a crankshaft (5) and one active expansion chamber (13) of a vairable volume allowing work to be produced and which is connected, by a passage (6), with the volume contained in the driving cylinder (2), characterized in that the said passage (6) comprises a shutter (7) thus allowing the said active expansion chamber to be isolated from or to be placed in contact with the dead volume, in such a manner that the engine works acoording to a four -phase thermodynamic cycle: * an isothermal expansion without work; * a transfer-slight expansion with work said o be quasi-isothermal; * a polytropic expansion with work; *an exhaust at ambient pressure.
