Combustion Analyzer XDI-CAx

Some of the signals that can be analyzed:

  • Peak Pressure and Angle of Peak Pressure
  • Knock Peak Pressure, Knock Index (based on Cyl. Pressure or based on Knock Sensor, or both)
  • IMEP, indicated Torque & Power per cylinder
  • CA50, Heat Release Rate, COV etc.
  • Actual Start of Injection (e.g. Current Probe on Injector)
  • Actual Ignition Timing (e.g. Current Probe on Coil Supply)
  • Intake / Exhaust Port Press. (e.g. Reversion, Scavenging)
  • Actual Fuel Pressure during Injection (Pulsations)

APPLICATION
2-12ch, CAN-output

This combustion analyzer has specifically been designed for engine control and dyno monitoring applications. The design incorporates a data acquisition board with 8 high resolution inputs for pressure transducers or other inputs and 3 inputs for trigger signals (crankshaft hall, crankshaft VR, camshaft or encoder), all in a robust machined aluminum enclosure with mil-spec Deutsch ASU
connectors. This robust design makes it resistant to vibration and high-temperatures. It features realtime dynamic pressure measurement of combustion or port pressure in spark-ignition or
compression ignition engines.

The analysis SW runs on every MS-Windows based PC or Tablet. For mobile use a preconfigured 10” Tablet is available on request.
The cycle based pre-processed characteristics can be sent on CAN-bus in real time to be post processed in another ECU or recorded on a datalogger together with your engine and dyno data. Additional CAN-HW is necessary.
