  • Optoelectric measuring device for monitoring combustion processes
    Patent number: 6320184
    Abstract: An optoelectronic measuring device for monitoring combustion processes in a combustion chamber of an internal combustion engine during operation is provided with optical sensors which are connected to an evaluation unit. The optical sensors may be located in a seal element bounding the combustion chamber. To obtain high measuring quality in a simple manner, the optical sensors each include a lens assembly having a focusing lens whose flat end opposite the combustion chamber is coincident with the focal plane of the focusing lens and is abutted by an end of at least one optical fiber.
