Default combustion in high power ICEs
Posts: n/a
Hi all. I am trying to calculate combustion in a high specific power gasoline ICE (not turbocharged). Does anybody know of deficiencies of the Weller and CFMI models when calculating combustion in this kind of engines? Using standard values of the coefficients bring to a peak pressure of 140 bar(!!!!) in both models. I have also tried to use Vectis with a similar model and using the standard values of the coefficients give similar results. Why? Any help apreciated.
