Abstract

Die Erfindung betrifft ein Verfahren zur Bewertung des Zustandes eines Kraftstoff/Luft-Gemisches und/oder der Verbrennung in einem Brennraum einer Brennkraftmaschine, wobei in einer Datenbank Mustersignale von Flammlichtsignalen, vorzugsweise die Flammenintensität (FI), mit zugeordneten Gemischzuständen abgelegt werden, wobei Flammlichtsignale, vorzugsweise die Flammenintensität (FI), der Verbrennung im Brennraum erfasst und so mit den abgelegten Mustersignalen verglichen werden, und wobei bei Übereinstimmung zwischen gemessenen und abgelegten Signalmustern auf den Zustand des Gemisches im Brennraum geschlossen wird. Um eine genaue und einfache Überwachung des Gemischzustandes und der Verbrennung zu ermöglichen, ist vorgesehen, dass gleichzeitig mit der Erfassung der Flammlichtsignale auch eine Druckmessung im Zylinder durchgeführt wird.
