  • Device for observing the processes taking place in the combustion chamber of an internal combustion engine during operation
    Patent number: 4643022
    Abstract: In order to observe and optically record the processes in the combustion chamber of an internal combustion engine during operation, at least one observation bore located in the wall of the combustion chamber is provided with a transparent window as well as an image pickup device, e.g. an endoscope, which may be inserted as far as to this window and is connected to an image recording unit by way of an image transmission device. In order to prevent the premature build-up of sooty deposits the window may be separated from the adjacent, cooled parts of the wall of the combustion chamber by a gap which will reduce the dissipation of heat.
