When I used ECFM+TKI to predict the knock combustion, the auto-ignition would occurs immediately when the combustion model is active. TKI was generated by the zero-D simulation. I don't know what's wrong. If the input parameter( such as T, P, egr, equivalence ratio in cell) is out of range of TKI, would auto-ignition occurs? Can someone help me or teach me how to generate TKI? Thank you vey much!

Hi,
If you are looking to create the TKI table there is an example for TKI Table Generation in Studio under the Chemistry Module. You could compare your setup with the example to see if there are any apparent issues with the table generation. |

Thanks for your reply!!! I have solved this proplem. The dilution species MUST be N2 rather than combustion products calculated by CEQ solver. However, the dilution effects of N2 are different with that of CO2, H2O. I want to know why CEQ can bot be used. Thks!
