摘要： A method retains exhaust gas in the combustion chamber of an internal combustion engine and compresses the exhaust gas during a charge change. A first fuel quantity is injected into the retained exhaust gas by direct fuel injection. A second fuel quantity is subsequently fed to the combustion chamber so that a homogeneous fuel/air mixture is obtained in the combustion chamber. An auto-ignition time of the fuel/air mixture which is formed from the first and second fuel quantities is set as a function of a quantity ratio of the first fuel quantity to the second fuel quantity.

摘要： In a method for operating an internal combustion engine, a control operation is provided for the combustion process, wherein an actual value of the crank angle of a 50% mass conversion point of the fuel to be converted during the combustion is determined taking into account a measurement signal of an ion current sensor which is arranged in a combustion chamber, and the crank angle of the 50% mass conversion point is adjusted to a set point value of the position of the 50% mass conversion point by varying at least one manipulated variable of the internal combustion engine which affects the combustion. The crank angle of the 50% mass conversion point is determined in a layered neural network in which the measurement results of the ion current sensor are logically combined with at least one further, continuously measured operating parameter of the internal combustion engine.

摘要： A method for operating a four stroke internal combustion engine in which the combustion position can be set/controlled/corrected. The phase position of intake and/or exhaust phase is shifted for this purpose. Compression ignition takes place at part-load, and spark ignition takes place at full load. In the event of a load change in the part-lead range, the theoretical shift in the combustion position is compensated by the shift in phase position of the intake and/or exhaust phase.
