ABSTRACT:
To sense light and light variations emanating from a flame upon occurrence of combustion in the combustion chamber of an internal combustion engine, and prevent contamination of the sensing window, a quartz-glass rod is fitted into a housing with a central opening therethrough, the quartz-glass rod being exposed to the interior of the combustion chamber, and pressed against the housing by an abutment sleeve secured in the housing by a rolled-over shoulder. The quartz-glass rod is in light-transmissive relation, for example in contact with a fiber optic cable.
