Title: Alcohol tables in ME7.5.10
Post by: automan001 on June 03, 2015, 04:25:33 AM
Found these "alcoholic" tables in a2l description file for ME7.5.10  ;D
Is this something related to E85 fuel?
An interesting idea came into my mind: simplified data model could be reused for methanol injection corrections.
I like idea of having something like KFDZWAL and KFZWOPDA and "falkg".
Is there FR for ME7.5.10 or a diagram showing how these tables are involved into calculation process?

KFBAKLAL "Faktor Beschleunigungsanreicherung (K+L-Anteil), Alkohol"
KFDZWAL "Delta Zьndwinkelkennfeld fьr Alkohol"
KFFWLAL "Kennfeld Warmlauffaktor, Alkohol"
KFHSTTAL "Faktor HeiЯstart, Alkohol"
KFLBTSAL "Lambdasoll fьr Bauteileschutz, Alkohol"
KFLFAL "Lambdakennfeld bei Teillast, Alkohol"
KFMADNF "Kennfeld MeЯfensteranfangdelta Alkohol abhдngig"
KFMRESAL "LLR: Basis Momentenreserve im LL und ll-nahem Bereich, Alkohol"
KFRTVAL "TV - Kennfeld (Lambdaregelung Reglerumschaltverzцgerung), Alkohol"
KFTATMAL "Kennfeld Abgastemperatur   f(nmot,rl), Alkohol"
KFVAKLAL "Faktor Verzцgerungsabmagerung (K+L-Anteil), Alkohol"
KFZWOPDA "optimaler Zьndwinkel Delta Alkohol abhдngig"
KFZWWLDA "Delta Zьndwinkel im Warmlauf fьr Alkohol"
KLFALK "Kennlinie Faktor Alkohol in Gemisch"
KLFALKGALV "Kennlinie Faktor Alkohol fьr Verbrauch"
KLFALKZW "Kennlinie Faktor Alkohol fьr Zьndung"
LAMFAAL "Lambda Fahrerwunsch, Alkohol"
falkg "Faktor Alkohol in Gemisch"
falkzw "Faktor Alkohol fьr Zьndung"

I can be completely wrong but for me it seems it is just for flexi-fuel cars (petrol/E85 and any mix of them).

Yes, they are for brasilian flex cars for example, ECU calculate k faktor to deal with diferent blend of álcool and gasoline and aply to these maps
