摘要： A method includes forming a combustible mixture by mixing generally homogeneously a first fuel and air and introducing this mixture into a cylinder, compressing the combustible mixture with a piston in a compression stroke, introducing a second fuel into a prechamber at an introduction-time before start of combustion thus creating a prechamber charge, in which the second fuel being of the same or different chemical composition and/or concentration with respect to the first fuel, and spark igniting the prechamber charge. Emission of the cylinder and/or mechanical stress of the cylinder caused by the combustion are monitored. If emissions and/or mechanical stress are above respective predetermined thresholds, individually for the at least one cylinder, the chemical composition and/or the amount of second fuel introduced into the prechamber, and/or temperature of the cylinder charge and/or spark timing , are changed.

摘要： A method for operating an internal combustion engine, in particular a gas engine having at least three cylinders, includes acquiring a cylinder-specific signal (pmax, E) from each cylinder. A reference value (pmedian, Emedian) is generated from the signals (pmax, E) from the cylinders, and at least one combustion parameter (Q, Z) of the corresponding cylinder is controlled as a function of the deviation of a signal (pmax, E) from the reference value (pmedian, Emedian). The signal (pmax, E) tracks the reference value (pmedian, Emedian), and the median of the signals (pmax, E) is generated as the reference value (pmedian, Emedian).
