Abstract
An internal combustion engine with rotatable bodies each received in a respective internal cavity. The engine includes at least one inlet port for each internal cavity in fluid communication with the combustion chamber(s) thereof at least during their intake phase and a beginning of their compression phase. The bodies are angularly offset with the beginning of the compression phase of the combustion chamber(s) defined by each body being simultaneous with at least a beginning of the intake phase of the combustion chamber(s) defined by a different one of the bodies. A respective conduit provides a fluid communication between an inlet port for each body and an inlet port for the different one of the bodies, with each conduit being in fluid communication with a plenum for receiving pressurized air. A method of feeding air to an internal combustion engine is also provided.
