Fiber optic spark plugs / FOSP
These spark plugs have an integrated fiber-optic system for optical combustion analysis in spark-ignition engines.
- Up to 12 optical windows to the combustion chamber
- Radial and/or axial direction of observation
- Adaptation of optical probes to almost any serial production spark plug
- Thread sizes M8, M10, M12, M14
The optical probes of the spark plug acquire combustion radiation in discrete areas of the combustion chamber. The acquired light intensity is conducted through optical fibers to highly sensitive optical amplifiers and converted to a voltage signal. The addition of optical windows to the serial production spark plug doesn’t affect its heat range, spark position or ignition characteristics.
