The exhaust gas recirculation cooler includes an external casing with an inlet and an outlet for an exhaust gas flow. A first tube bundle and a second tube bundle, each with an inlet and an outlet for a coolant, are located inside the external casing so that the exhaust gas flow flows through the first tube bundle and the second tube bundle in series. A bypass passage conveys the exhaust gas flow from downstream the first tube bundle to the outlet of the external casing bypassing the second tube bundle. The bypass passage is located inside the external casing between the first tube bundle and the second tube bundle.

Abstract: An arrangement for control of an engine, the arrangement having a super-charger adapted to be disposed between an air intake and an inlet manifold of the engine, the super-charger device being adapted to boost the pressure of the intake air to the engine. The arrangement also has an exhaust gas recirculation, EGR, system, and a super-charger bypass conduit arranged to facilitate a variable bypassing of the super-charger device, the EGR flow level to be controlled such that the effect of the EGR system on the combustion process of the engine can be continuously varied. The arrangement is further adapted to sense a boost pressure level and an inlet temperature level of the inlet air at the inlet manifold of the engine, and to adjust said super-charger bypass and EGR level in order to reach a pre-determined inlet temperature and boost pressure level, thus facilitating control of the combustion process.
