Rotary combustion engine and associated combustion method

A rotary combustion engine including:

• a frame forming a stator in which is formed a cavity extending along a longitudinal axis and having at least one first transverse dimension termed greater width and a second transverse dimension termed lesser width, the longitudinal axis being immobile relative to the frame,
• a rotor including a cylindrical body extending longitudinally in the cavity and mounted to be mobile in rotation in the frame about the longitudinal axis, the cylindrical body having a diameter corresponding to the lesser width of the cavity and defining two opposite zones flush with a surface of the cavity forming a bottleneck that separates the cavity in a sealed manner into an oxidant gas intake compartment and a burnt gas exhaust compartment, each of the intake and exhaust compartments being delimited by an external face of the cylindrical body and the surface of the cavity and being respectively in fluidic communication with an oxidant gas intake inlet and a burnt gas exhaust outlet formed in a wall of the frame,
• the rotor including at least one member for driving gases contained in the compartments mounted in a longitudinal opening formed in the cylindrical body of the rotor and configured to be driven in rotation by the cylindrical body about the longitudinal axis,
• the engine including means whereby the free ends of the drive members are flush with an internal face of the cavity by sliding of the drive members in the opening in a direction perpendicular to the longitudinal axis between a minimal position in which the respective free end is flush with the internal face of the cavity at the lesser width and a maximal position in which the respective free end is flush with the internal face of the cavity at the greater width, and
• the alternated combustion device including means for injecting fuel into a combustion chamber and combusting the fuel therein fluidically connected to an oxidant gas inlet in fluidic communication with the intake compartment and to a burnt gas outlet in fluidic communication with the exhaust compartment via an alternated fluidic communication device configured to place the combustion chamber alternately in fluidic communication with the oxidant gas inlet and the burnt gas outlet.
