Abstract
A method for evaluating the state of a fuel-air mixture and/or the combustion in a combustion chamber of an internal combustion engine, with sample signals of flame light signals being stored in a database, and with flame light signals of the combustion in the combustion chamber being detected and compared with the stored sample signals, and with an evaluation of the state being output in the case of coincidence between the measured and stored signal patterns. In order to enable the monitoring of the combustion in the simplest possible way the sample signals in the database are stored with the assigned emission values and an evaluation of the state of the combustion is performed with respect to the obtained emissions in the case of coincidence between the measured and stored signal patterns for the combustion chamber of the respective cylinder.
