Method and apparatus for investigation of the mixture formation and / or combustion in a cylinder of an internal combustion engine

摘要

A method for examining the mixture formation and / or combustion in a cylinder of an internal combustion engine, in the case of a light source by the combustion chamber and at least one window in the cylinder with a detector light passing through it is detected and evaluated, characterized in that, in the evaluation of the decrease in the from the detector (14), detected light intensity of light or radiation density is determined, which consists of a contamination of the window (10) or of different over the window (10) during a measurement sites distributed fired operation of the internal combustion engine, and from the decrease in a measure of a contamination of the window (10) or of the different over the window (10) distributed measuring points is calculated and from this information about the combustion and / or mixture formation in the window (10) or to the measurement sites adjacent regions of the combustion chamber (9) are derived.
