Abstract: In an internal combustion engine with a cooling system and an exhaust gas recirculation (EGR) system including an EGR heat exchanger with a coolant inlet opening connected to a coolant outlet opening of the engine for receiving coolant therefrom and the engine including a coolant collecting rail mounted directly to the engine and having a coolant inlet opening connected to the EGR heat exchanger and at least one other coolant inlet opening in communication directly with at least one other coolant outlet opening of the engine.

Abstract: In an exhaust gas recirculation line holder of an internal combustion engine wherein a line section of an exhaust gas recirculation line is integrated into the holder which is supported on the engine block and/or the vehicle frame, the holder is provided with a shaped part, in particular a cast part, with the line section of the exhaust gas recirculation line formed therein and a support structure also being formed integrally with the holder so that manufacturing costs, assembly time and assembly expenditure are reduced.

Abstract: In an apparatus for measuring an exhaust gas recirculation flow through an exhaust gas recirculation line of an internal combustion engine, the exhaust gas recirculation line has a constriction region and a flange structure integrally formed therewith, said communication line extending from the constriction region to the flange structure on which a differential pressure sensor is disposed and being formed into the wall of the exhaust gas recirculation line so as to be in communication with the differential pressure sensor mounted on the flange structure for determining the exhaust gas flow through the recirculation line.
