Abstract
A method for setting a supercharged internal combustion engine having exhaust-gas recirculation in which exhaust gas is fed from an exhaust tract of the engine arranged upstream of a turbine into an intake tract of the engine arranged downstream of a compressor. The fuel quantity injected into the combustion spaces of the internal combustion engine is set in dependence on the load. To adapt the exhaust-gas recirculation to any operating point of the engine, there is a provision for recirculating exhaust gases from only some of the cylinders, which assume the function of exhaust-gas dispenser cylinders, and for setting the injection of fuel into these dispenser cylinders independently of the remaining cylinders.
