Combustion Analyzer XDI-CAx

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)

 

Description

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.

Supporting Material

California Proposition 65

 Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are:

lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and
arsenic and chromium from chemically treated lumber.

Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
