Abstract:
A system for providing exhaust gas recirculation in a multi-cylinder compression ignition internal combustion engine having an intake side and an exhaust side, the system comprising:an EGR valve in communication with the exhaust side of the engine to selectively divert a portion of exhaust from the internal combustion engine through an EGR circuit to an intake side of the engine; a turbocharger having a turbine in fluid communication with the exhaust side of the engine and the EGR circuit and a compressor in fluid communication with the intake side of the engine; a full flow cooler disposed within the EGR circuit for selectively cooling recirculated exhaust gas passing therethrough, wherein substantially all engine coolant passes through the full flow cooler; a control module in communication with the EGR valve and the turbocharger for controlling flow of exhaust gas through the EGR circuit; and means for reducing formation of condensation within at least one of the intake side and exhaust side of the engine.
