Combustion Analyzer XDI-CAx

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 real-

time 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 pre-

configured 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.
