摘要： An internal combustion engine (1) having a regulating device (C) wherein an air-fuel mixture with a combustion air ratio (λ) which is adjustable by the regulating device is burnt in the internal combustion engine, wherein the regulating device (C) has a power output regulating circuit adapted to adapt an actual output (Pg) of the internal combustion engine (1) to a reference power output (Pdg) of the internal combustion engine (1) by way of an adjustment of the combustion air ratio (λ), and a NOx emission regulating circuit adapted by way of a functional relationship (2) to actuate actuators influencing a charge pressure as an alternative parameter for the NOx emission by the charge pressure such that a charge pressure reference value (pdim) can be set for each reference power output (Pdg) of the internal combustion engine.

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

摘要： A method of operating an internal combustion engine, in particular a gas engine, comprising at least one combustion chamber to which a charge air is fed with a variable charge pressure and/or a variable amount of charge air, wherein a cylinder pressure value is ascertained from at least one measurement value of a sensor arranged in the at least one combustion chamber, wherein the cylinder pressure value is regulated by altering the charge pressure and/or by altering the amount of charge air as a setting value or values to a cylinder pressure target value, wherein the cylinder pressure target value is selected in dependence on a power of the internal combustion engine.

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