Method for evaluating the status of a fuel/air mixture

摘要

The method involves storing sample signals of flame light signals in a database, where the flame light signal, particularly the flame intensity of the combustion in the combustion chamber is detected and is compared with the stored sample signals. An evaluation of the state is outputted in the case of coincidence between the measured and stored signal patterns. The sample signals in the database are stored with the assigned emission values. An evaluation of the state of the combustion is performed with respect to the obtained emissions. An independent claim is also included for a device for executing a fuel-air mixture state evaluation method.
