Improved combustion control for combustion engines

An arrangement for control of an engine, the arrangement comprising a super-charger 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 further comprising 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 being arranged to be controlled such that the effect of the EGR system on the combustion process of the engine can be continuously varied, the arrangement further being 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 predetermined or preferred inlet temperature and boost pressure level, thus facilitating control of the combustion process.
