1. A method for generating a homogeneous mixture for an auto-ignition internal combustion engine and for controlling a combustion process, the internal combustion engine including an injection system and at least one cylinder/piston unit connected to an intake device and having a combustion space, the method comprising the steps of:

  • one of recirculating hot exhaust gas from a previous combustion cycle into one of the combustion space and the intake device and retaining hot exhaust gas in one of the combustion space and the intake device;

    injecting fuel by the injection system into the one of the recirculated hot exhaust gas and the retained hot exhaust gas to generate a homogeneous fuel/air mixture;

    cooling the homogenized fuel/air mixture by at least one of expansion cooling in the respective cylinder/piston unit, isentropic compression in the respective cylinder/piston unit, expansion cooling of fuel/air mixture homogenized in at least one further cylinder/piston unit, external cooling of a fuel/air mixture homogenized in at least one further cylinder/piston unit; and

    recirculating the cooled fuel/air mixture into the intake device.
