Patent ID: 8061335

Claim:
An internal combustion engine having a plurality of cylinders comprising: an air intake line capable of carrying intake air towards an engine intake manifold; an exhaust line capable of collecting exhaust gas from an exhaust manifold; a turbocharging system having at least one compressor stage driven by at least one turbine capable of compressing intake air entering the intake manifold; intake air cooling means having at least one charge air cooler located upstream from the intake manifold; and an exhaust gas recirculation (EGR) line rerouting a portion of the engine's exhaust gas into the air intake line at a point located upstream from the at least one intake cooler wherein the internal combustion engine further comprises a cooling branch deviating a portion of the intake air from a point of the air intake line located downstream from at least one compressor towards an EGR cooler thermally connected to the EGR line, and wherein the air intake line comprises at least a low pressure compressor and a high pressure compressor located downstream from the low pressure compressor, and the cooling branch inlet is connected to the air intake line between the low pressure and the high pressure compressors.
