Disclosed is a three rotor engine of the intermeshing lobe and groove type wherein the rotors are transversely aligned and sealingly cooperate with a casing to provide a power rotor, an abutment rotor and a scavenging rotor. The scavenging rotor provides for a positive formation of an air which forces exhaust gases out a primary exhaust port and also aids in air intake through a primary air intake port by expanding the chamber defined between adjacent lobes which provides for the formation of a positive air charge in the chamber for use in the combustion engine. The scavenging rotor helps in reducing unburnt fuel emissions in the exhaust as it provides a charge of fresh air into the exhaust from the abutment or middle rotor to allow complete combustion of any fuel still remaining unburnt in such exhaust.
