Beschreibung
Zusammenfassung:	A rotary combustion engine having a planetary rotor and a side intake port is provided with an internal exhaust gas recirculation system that is operable to connect the trailing region of the working chambers and the space below the trailing apex seal to the annular space between the side seals and oil seals on one rotor side only when the chambers near the end of the exhaust phase whereby the differential between the pressure of the exhaust gases and the vacuum of the inlet mixture causes the exhaust gases rich in unburned hydrocarbon that are in the trailing regions of the chamber during the exhaust phase to flow through the annular space to the intake port and thereafter be recirculated through the compression and expansion phase.
