System for predicting at least one characteristic parameter of a fuel

A method of regulating an internal combustion engine having a plurality of cylinders is provided, wherein each of the individual cylinders can be deactivated in accordance with a predeterminable pattern depending on a required power output, wherein the predeterminable pattern comprises a time sequence of commands for ignition and commands for skipping ignition, and wherein the predeterminable pattern is derived with a calculation specification in such a way that spacing between the individual cylinders intended for skipping in relation to a firing order is an odd number and is preferably in coprime relationship with the number of cylinders.

Method of regulating an internal combustion engine including omission of cylinder firings

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.

Method of operating an internal combustion engine

An internal combustion engine () having a regulating device (C) wherein an air-fuel mixture with a combustion air ratio (&#x3bb;) 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 (P) of the internal combustion engine () to a reference power output (P) of the internal combustion engine () by way of an adjustment of the combustion air ratio (&#x3bb;), and a NOx emission regulating circuit adapted by way of a functional relationship () 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 (p) can be set for each reference power output (P) of the internal combustion engine.

Internal combustion engine having a regulating device

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 (p, 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 (p, E), and a cylinder-specific reference cylinder value (p', E&#x2032;) is set for the first cylinder signal (p, 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 (p, E) from the reference cylinder value (p&#x2032;, E&#x2032;), and the first cylinder signal (p, E) tracks the reference cylinder value (p&#x2032;, E&#x2032;).

Method for operating an internal combustion engine

A method for operating an internal combustion engine, in particular a gas engine, having at least three cylinders, wherein a cylinder-specific signal (p, E) is acquired from each of the at least three cylinders, wherein a reference value (p, E) is generated from the cylinder-specific signals (p, 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 (p, E) from the reference value (p, E), whereupon the cylinder-specific signal of the one of the at least three cylinders (p, E) follows the reference value (p, E), wherein a median of the cylinder-specific signals (p, E) is generated as the reference value (p, E).
