    Abstract: In a method of operating a supercharged internal combustion engine in which exhaust gas is retained in the combustion chamber during a charge change, wherein the engine is operated with compression ignition or with spark ignition depending on the operating point and in which a charge pressure can be established for the fresh air supplied to the combustion chamber, and the exhaust gas is compressed during the charge change, and a first fuel quantity is optionally injected into the retained exhaust gas and a second fuel quantity is subsequently supplied to the combustion chamber, such that a homogeneous fuel/air mixture is formed in the combustion chamber, the retained exhaust gas quantity in the combustion chamber is corrected in such a way that the center of the combustion is displaced in the direction toward a set point value when the center of the combustion deviates from the set point value because of a change in the charge pressure of the fresh air or because of a change in the temperature of the fresh air.

    Abstract: In a method for controlling a reciprocating piston internal combustion engine having a plurality of cylinders in a compression ignition operating mode in which a lean fuel/air mixture is burnt, wherein an actual value of at least one characteristic variable which is influenced by the fuel burning process is compared with a pre-definable set point value in order to form a control value, with which the setting of an operating parameter affecting the mixture formation is adjusted in order to approximate the actual value of the characteristic variable, in a first control circuit, a mean value of the characteristic variable is determined and adjusted to an overall set point value using the control value, which is supplied to all the cylinders, and, in a second control circuit, characteristic variables which are measured at each cylinder are matched by means of individually determined control values in order to ensure a stable combustion in the compression operating mode.
