REGISTRATION OF KNOCKING GASOLINE ENGINES WITH METHODS OF PATTERN RECOGNITION

ERFASSUNG DES KLOPFENS VON OTTOMOTOREN MIT METHODEN DER MUSTERERKENNUNG

Knocking in gasoline engines is to be detected with methods of pattern recognition. Basic processes are shown first for understanding of the knock process; also process required in the combustion chamber, which can lead to knocking, is discussed. Discussed are physical variables for registration of knocking and the required measurement technology. The model of a generaal recognition system of examined. The first levels of the recognition system are described. Possible classification techniques are examined. Introduced are two techniques for the description of an engine operation state. Inferences are taken from the results for the conception of a real time knock measuring method. Some points of further interesting investigations about knock recognition are addressed.
