Fiber Optical Spark Plug Sensor

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.

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

Sensor Specifications
measured quantities:        fuel or residual (recirculated exhaust)
                                      gas concentration transients
precision:                        < 2%
data rate:                        30kHz
data acquisition:               crank angle resolved multiple cycles
