Abstract:
1. An intake system for an internal combustion engine, the internal combustion engine including a primary cooling system, the intake system comprising: an intake charge compressor configured to deliver a compressed intake charge, comprising exhaust gas from an exhaust system and ambient air, through an intake charge conduit and to the internal combustion engine; a compressed intake charge cooler in fluid communication with the intake charge conduit and configured to receive, cool and transit the compressed intake charge therethrough; a secondary cooling system, independent of the primary cooling system, in fluid communication with the compressed intake charge cooler through a cooling system conduit having a cooling medium therein; a low temperature cooler in communication with the cooling medium and configured to receive the cooling medium through the cooling system conduit of the secondary cooling system; an exhaust gas conduit extending between the exhaust system of the internal combustion engine and an intake of the intake charge compressor for delivery of recirculated exhaust gas thereto; and an exhaust gas cooler in fluid communication with the exhaust gas conduit and configured to receive, cool and transit the recirculated exhaust gas therethrough, wherein the secondary cooling system is in fluid communication with the exhaust gas cooler through the cooling system conduit for delivery of the low temperature cooling medium from the secondary cooling system to, and through, the exhaust gas cooler.
