Method of regulating an internal combustion engine including omission of cylinder firings
First Claim
1. A method of regulating an internal combustion engine having a number of cylinders, comprising:
- deriving a predeterminable pattern comprising a time sequence of ignition commands for ignition of individual cylinders of the number of cylinders and non-ignition commands for skipping ignition of the individual cylinders of the number of cylinders, wherein the predeterminable pattern is derived by a calculation with spacing between the individual cylinders derived for non-ignition commands in relation to a firing order is an odd number;
varying with respect to time, after a predeterminable time interval, the predeterminable pattern by adding ignition commands for a number of at least one individual cylinder and by adding non-ignition commands for the same number of at least one individual cylinder;
excluding a number of at least one individual cylinder from non-ignition commands of the predeterminable pattern for regular ignition without adaptation to a load demand; and
activating or deactivating individual cylinders of the predeterminable pattern depending on a required power output by the internal combustion engine.

Abstract
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.
