Patent ID: 6899090

Claim:
An internal combustion engine system, comprising: an internal combustion engine including an exhaust manifold with an exhaust outlet and an intake manifold with an air inlet; an engine exhaust conduit in fluidic connection with the exhaust outlet and the inlet of a first control valve with one inlet and two outlets; a high pressure exhaust gas recirculation (EGR) fluidic connection between a first outlet of the first control valve and the air inlet of the intake manifold; an EGR cooler disposed along the high pressure EGR fluidic connection at a point downstream of the first control valve and upstream of the air inlet; a turbocharger having an exhaust gas turbine with an input in fluidic connection with a second outlet of the first control valve and with an output, the turbocharger further having a compressor with an input and an output; an EGR supply conduit in fluidic connection with the output of the exhaust gas turbine and a fresh air inlet in fluidic connection with the input of the compressor, with a second control valve disposed along the EGR supply conduit; and an intake manifold conduit in fluidic connection with the output of the compressor and the air inlet of the intake manifold.
