International ClassesF02D 041/14G01L 023/16 AbstractAn internal combustion engine is provided having a luminosity detector and an arrangement for measuring and controlling combustion phasing based on the location of particular gain independent parameters of the luminosity signal. The gain independent luminosity parameters are used to provide a basis for adjusting various parameters of the engine like fuel injection timing so that at least one gain independent parameter is located at a desired timing point in the combustion cycle to control combustion phasing. Alternatively, these gain independent luminosity parameters are used to determine the time in the combustion cycle at which certain combustion conditions occur. In this embodiment, the determined time of a combustion condition provides a basis for adjusting engine parameters so that the combustion condition occurs at a desired time in the combustion cycle to control combustion phasing.Other References
