Abstract
A method for carrying out the operation of an internal combustion engine, wherein liquid fuel injection amounts are injected at cylinders of a group of cylinders of the internal combustion engine in the context of injection events, wherein in a first step, a first cylinder of the group with the strongest knocking tendency over a time period is determined, and in a second step an injection correction occurs such that the injection events at the first determined cylinder can be sequentially reduced in their injection duration or injection amount by a first correction value, while the injection duration or injection amount of the injection events at the other cylinders of the group are sequentially increased by a second correction value.

A method for carrying out operation of a combustion engine, wherein liquid fuel-injection amounts are injected at cylinders of a group of cylinders of the combustion engine during injection events;
- the method comprising the steps of:
- in a first step, determining a first cylinder of the group that has a greatest tendency to knocking over a time period;
- and
- in a second step, carrying out an injection correction so that injection events at the first determined cylinder are each subsequently reduced in injection duration or injection amount by a first correction amount, whereas the injection duration or injection amount of the injection events at further cylinders of the group are each subsequently increased by a second correction amount.
