Method for operating an internal combustion engine
First Claim
1. A method of operating an internal combustion engine having at least two cylinders, said method comprising:
- acquiring a cylinder-specific first cylinder signal from each of the at least two cylinders via a sensor; and
controlling a combustion parameter of each of the at least two cylinders as a function of the respective cylinder-specific first cylinder signal using a control device;
wherein said controlling comprises setting a cylinder-specific reference cylinder value for the cylinder-specific first cylinder signal for each of the at least two cylinders via the control device such that at least one of NOx emissions and combustion efficiency of the at least two cylinders is identical or similar, and using the control device to adjust the combustion parameter of each of the at least two cylinders as a function of a deviation of the respective cylinder-specific first cylinder signal from a corresponding cylinder-specific reference cylinder value such that the respective cylinder-specific first cylinder signal tracks the corresponding cylinder-specific reference cylinder value.

Abstract
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′).

27. An internal combustion engine comprising:
-
at least two cylinders; a sensor for acquiring a cylinder-specific first cylinder signal from each of said at least two cylinders; and a control device for controlling a combustion parameter of each of said at least two cylinders as a function of the respective cylinder-specific first cylinder signal; wherein said control device is configured to set a cylinder-specific reference cylinder value for the cylinder-specific first cylinder signal for each of said at least two cylinders such that at least one of NOx emissions and combustion efficiency of the at least two cylinders is identical or similar, and to adjust the combustion parameter of each of said at least two cylinders as a function of a deviation of the respective cylinder-specific first cylinder signal from a corresponding cylinder-specific reference cylinder value such that the respective cylinder-specific first cylinder signal tracks the corresponding cylinder-specific reference cylinder value.
