Abstract
An internal combustion engine comprises a compressor disposed in an intake system configured to compress combustion air and deliver it to cylinders of the engine. A compressor inlet assembly has a combustion air inlet, in fluid communication with, and configured to receive combustion air from the intake system. A combustion air passage extends through the assembly to an outlet located downstream of the inlet and is configured for fluid communication with the compressor. An EGR mixing conduit is disposed within the compressor inlet assembly and has an EGR inlet configured for fluid communication with, and receipt of EGR from, an EGR supply conduit. An EGR passage extends from the EGR inlet to an EGR supply annulus disposed about the combustion air inlet opening and a plurality of EGR ports extend between the EGR supply annulus and the combustion air passage for delivery of EGR thereto.
