ABSTRACT:
The invention relates to a measuring device (1) for detecting processes in the combustion chamber of an internal combustion engine, comprising a pressure sensor (3) which is arranged to be inserted into a bore hole of the internal combustion engine which opens into a combustion chamber, with the pressure sensor (3) comprising at least one optical light guide (6) optically opening into the combustion chamber, and with an optical injection element (8) being arranged preferably in the opening region into the combustion chamber. In order to enable performing simultaneously a pressure measurement and optical combustion chamber monitoring at the same place of the combustion chamber, it is provided that the optical injection element (8) is soldered into a pressure membrane (5) of the pressure sensor (3) or into the housing (2) of the pressure sensor (3).
