Internal combustion engine operating method, involves determining position value, at which ignition spark is lowered, based on position reference value, to maintain predetermined position reference value

摘要

The method involves predetermining a position reference value (alpha50soll), at which fifty percentage of the fuel energy (pkzu) guided to a combustion chamber of an internal combustion engine is converted. An influence of conversion of the energy supplied to the combustion chamber is specified as a result of a charge motion and/or portion of the remaining gases in the combustion chamber of the internal combustion engine. A position value (alphazzp), at which an ignition spark is lowered, is determined based on the position reference value, to maintain the reference value.
