Combustion Model for CAI/HCCI - AVL FIRE
 

HI
I work with AVL FIRE trying to make combustion analysis for compression auto-ignition engine chamber. The problem is I don't really know which one of the AVL's combustion models is appropriate for CAI/HCCI engine.

My analysis proceeds with valves closed, without a plug (just compression, injection, combustion, decompression)

For ignition model I chose HCCI ignition model. How to determine parameters: AQ, AB, A0F1, A0F4 ???

I will be thankful for any clue
regards,
Patryk
