Abstract

A system for recirculating exhaust gas in an internal combustion engine in which a connecting line for the recirculated exhaust gas is connected to an air intake tube with cooling elements arranged in between. The cooling element may be, for example, a cooling channel for liquid coolant integrated into the flange connecting the connecting line to the air intake tube, or it may be another heat conductive element.
