Beschreibung
Zusammenfassung:	An ignition detector, a flue supply device and a knock detector are provided on the respective cylinders. In the event of a knock being detected in at least one cylinder, a control device changes the supplied quantity of fuel to the individual cylinders. The control device operates the knocking cylinder with a richer fuel mixture, and operates the remaining non-knocking cylinders with a leaner fuel mixture. Independent claims are included for further internal combustion engines; a control device; a motor vehicle; a method of operating an internal combustion engine; a computer program for implementing a microprocessor based control device; and a data carrier for the computer program. Zum stöchiometrischen Betreiben eines Verbrennungsmotors mit wenigstens zwei Zylindern werden beim Abtasten eines Klopfsignals an wenigstens einem Zylinder die klopfenden Zylinder jeweils um eine vorbestimmte Anfettungsmenge von Kraftstoff angefettet, wobei die übrigen Zylinder jeweils um eine vorbestimmte Abmagerungsmenge von Kraftstoff abgemagert werden. Alternativ dazu wird unter bestimmten Bedingungen bei Klopfereignissen zur Erhöhung der Klopfgrenze nur das Gemisch des betreffenden Zylinders kurzzeitig angefettet, um das Klopfen zu unterbinden. Die Vorzündung bleibt dabei unverändert.
