Hab gerade meinen 1.8t auf Ethanol umgebaut und würde gerne wissen bei welchen Lambdawert Ethanol die beste Leistung hat.

Auf was stimmt ihr ab?

Keiner was zu sagen dazu.
Selber fahre ich 0,85 abfallend auf 0,8

Interessant wird's ab Seite 10 : http://dragracing.de/showthread.php?7053...ht=Ethanol

Technical facts about the mentioned fuels:

E85 requires 42% more fuel to reach stoich even if that is not what you may come up with when doing calculations based on the table below. This is because the injector flow is slightly different when using E85 among many other things I can´t really think of at this time (will be added at a later time).

Fuel ........................ AFRst ........ FARst ....... Equivalence Ratio ... Lambda
Gas stoich ................ 14.7 .......... 0.068 ................ 1 ................... 1
Gas max power rich .... 12.5 .......... 0.08 ................. 1.176 .............. 0.8503
Gas max power lean .... 13.23 ........ 0.0755 .............. 1.111 ............. 0.900
E85 stoich .................. 9.765 ....... 0.10235 ............ 1 ................... 1
E85 max power rich ...... 6.975 ....... 0.1434 .............. 1.40 ............... 0.7143
E85 max power lean ..... 8.4687 ...... 0.118 ............... 1.153 .............. 0.8673
E100 stoich ................ 9.0078 ...... 0.111 ............... 1 .................... 1
E100 max power rich .... 6.429 ........ 0.155 .............. 1.4 .................. 0.714
E100 max power lean .... 7.8 .... ...... 0.128 .............. 1.15 ................ 0.870


So wie ich das lese hat E85 die max Leistung von Lambda 0,72 bis 0,86
Ist aber ein grosser bereich.
