Spark plug for internal combustion engine, has housing with borehole for accommodating fiber-optic light guide that opens out into combustion chamber, where axis of borehole runs inclined to axis of other borehole in housing
2007 (English)Patent (Other (popular science, discussion, etc.))
The spark plug has a longitudinal borehole (3) formed in a housing (2) for holding an insulator. The housing has a borehole (10) for holding a pressure measuring device. Another borehole (21) is provided in the housing for accommodating a fiber-optic light guide that opens out into a combustion chamber. An axis (21') of the borehole (21) runs inclined to an axis (10') of the borehole (10), where the longitudinal borehole is arranged parallel to a spark plug axis, and the axis of the borehole is provided at a distance from the spark plug axis (1').
