Publication number: 20080202731Abstract: The invention relates to a one-piece turbulence insert for a heat exchanger (1), particularly for a radiator of a motor vehicle, comprising an essentially corrugated profile. The turbulence insert (24) has a number of sections (41-45) with corrugated profiles that extend in the same direction of the extension of the corrugations and which, perpendicular to the direction of the extension of the corrugations, are offset from one another. In order to enable a better thermodynamic efficiency, the turbulence insert (24) has a number of sections (27-32, 41, 45) with corrugated profiles extending in different directions of extension of the corrugations.Type: ApplicationFiled: August 1, 2005Publication date: August 28, 2008Applicant: BEHR GMBH & CO.

Publication number: 20080190108Abstract: The invention relates to an exhaust gas turbocharger internal combustion engine comprising at least one cylinder in which a fuel-air mixture which is pre-compressed by means of a compressor (10) is compressed and burned. Exhaust gas is created, that is evacuated from the cylinder and released in a turbine (19). Part of the exhaust gas evacuated from the cylinder is recirculated, before it is released in the turbine (19), via a high-pressure recirculation system provided with an exhaust gas cooling device comprising at least two cooling circuits that are guided through heat exchanging blocks (26,27) that are successively connected in the flow direction of the exhaust gas. The air of the invention is to create an exhaust gas turbocharger internal combustion engine that can be economically produced and has a high output.Type: ApplicationFiled: January 16, 2006Publication date: August 14, 2008Applicant: BEHR GMBH & CO.
