Abstract

An internal combustion engine including internal cavities slidingly receiving a respective piston to define a respective combustion chamber, at least one inlet port for each internal cavity in fluid communication with the combustion chamber at least during the intake phase and a beginning of the compression phase, at least one exhaust port for each of the internal cavities and in fluid communication with the combustion chamber during the exhaust phase, a plenum for receiving pressurized air, and conduits in fluid communication with the plenum. Each conduit defines a fluid communication between a first respective internal cavity and a second respective internal cavity through the inlet ports. The combustion chamber of the first respective internal cavity undergoes the beginning of the compression phase simultaneously with the combustion chamber of the second respective internal cavity undergoing the beginning of the intake phase.
