Abstract
An exhaust gas turbocharger internal combustion engine is disclosed including at least one cylinder in a fuel-air mixture is pre-compressed by a compressor and compressed and burned. Exhaust gas is evacuated from the cylinder and released in a turbine, wherein part of the evacuated exhaust gas is recirculated before being released in the turbine, via a high-pressure recirculation system including an exhaust gas cooling device including at least two cooling circuits guided through heat exchanging blocks successively connected in the flow direction of the exhaust gas. The heat exchanging block arranged furthest downstream in the flow direction of the exhaust gas is vertically arranged such that exhaust gas passes through the block parallel to the working line, wherein a condensate collection and/or evacuation device is provided on the lower end of the block.
