Patent ID: 7921648

Claim:
An exhaust gas turbocharger internal combustion engine comprising: at least one cylinder, in which a pre-compressed fuel-air mixture is compressed and combusted, wherein exhaust gas is produced, which is discharged from the cylinder and expanded, wherein a part of the exhaust gas discharged from the cylinder is recirculated, before the exhaust gas is expanded, a high-pressure recirculation system comprising: a compressor, a turbine, and an exhaust gas cooling device, wherein the exhaust gas cooling device comprises: at least one cooling circuit comprising a first heat transfer block and a second heat transfer block, the first heat transfer and second heat transfer blocks being connected one after the other in the flow direction of the exhaust gas, wherein the second heat transfer block has a top end and a bottom end; wherein the second heat transfer block is arranged at the farthest possible downstream position in a flow direction of the exhaust gas and is arranged vertically so that exhaust gas flows through the second heat transfer block parallel or essentially parallel to an effective line of the force of gravity from the bottom end to the top end or from the top end to the bottom end, and recirculated exhaust gas flowing through the second heat transfer block precipitates condensate in the second heat transfer block; and wherein a condensate collection and/or discharge device is provided at the bottom end of the second heat transfer block.
