Fiber Optical Spark Plug Sensor

LaVision's innovative Spark Plug Sensor measures crank angle resolved fuel (lambda-values) or exhaust gas concentrations at the spark plug location of standard SI-engines without the need of any mechanical modifications and under real fuel conditions. The sensor is available with M12 or M14 threads. An M5 sensor without spark plug functionality can be used for standard bores of the engine.

Applications

• engine development:
  direct-injection engines, HCCI engines
• engine optimization:
  in-cylinder mixture formation, knocking
  misfire, exhaust gas recirculation
• check up of engine simulation models
