COOLING SYSTEM FOR AN ENGINE HAVING HIGH PRESSURE EGR AND MACHINE USING SAME

摘要

A machine (10) includes an internal combustion engine (12) having an intake manifold (24) and an exhaust manifold (28). An intake air conduit (26) extends from a compressor (38) of a turbocharger (36) to the intake manifold (24) and a charge air cooler (20) is disposed along the intake air conduit (26). An exhaust conduit (30) extends from the exhaust manifold (28) to a turbine (40) of the turbocharger (36). The machine (10) also includes a recirculation conduit (32). An inlet of the recirculation conduit (32) connects to the exhaust conduit (30) and an outlet of the recirculation conduit (32) connects to the intake air conduit (26) upstream of the charge air cooler (20). The machine (10) also includes a radiator (16) fluidly connected to the internal combustion engine (12). The charge air cooler (20) is positioned for receiving ambient air moved through the radiator (16) by a radiator fan (18, 19).
