ABSTRACT:
An improved rotary engine (12), wherein the improvement comprises a facility (58) for transferring any remaining exhaust gases from a first center well (16) in a housing (14) of the engine (12) into a cavity (34) of a second rotor (32) in a second well (18) in the housing (14) during the expansion cycle. An assembly (62) is for purging any remaining exhaust gases from the cavity (34) of the second rotor (32) in the second well (18) back into an air intake port (44) in the housing (14). An assembly (70) is for ejecting the compression of any fresh air and trapped exhaust gases into an exhaust port (48) in the housing (14) during the meshing of a piston (28) on a first rotor (26) in the first center well (16), with a cavity in a third rotor (38) in a third well (22) in the housing (14). A unit (78) is for drawing fresh air from the air intake port (44) into the cavity (40) in the third rotor (38), when the piston (28) of the first rotor (26) starts to exit from the cavity (40) in the third rotor (38).
