Dear All, I'm working on my thesis with AVL FIRE. I have modelled a SI engine combustion chamber and simulated only compression and expansion strokes.
I have got the results. The work per cycle is matching exactly with the actual engine.

But how to calculate the loses related to heat loss to the engine walls, volumetric losses, and charge exchange loop from the simulation results.

I have attached the 2d results here in Excel sheet

Can anyone please help me with this. Thanks in advance...
