English term

air/fuel ratio sweep

English to German Tech/Engineering Automotive / Cars & Trucks ignition control
Comes up four times in the description of the figures/drawings of an automotive patent, e.g.
"Fig. 14 illustrates an *air/fuel ratio sweep* vs. crank angle". Can't show the diagrams to which the descriptions refer but their Y-axes all show voltage values between 0.00 and 5.00, if that helps at all. None of my ideas seems to fit. Can anyone help? Thanks a million.

@Jeannette: In diesem Falle ist mit *sweep* m.E. eine Serie von Messungen gemeint.
Jeannette Eckel (asker) Mar 28, 2008:
Hi Tilman, kann man "sweep" und "measurement" in diesem speziellen Fall synonym verwenden?
Tilman Lichter Mar 28, 2008:
@Jeannette: In that case I'd use *Luft-Brennstoff-Verhältnismessung*.
Jeannette Eckel (asker) Mar 28, 2008:
Hi Tilman, thanks a lot for your suggestion. I think you understood correctly what that diagram is about. The problem is: I found Google hits like "the fuel/air ratio sweep is started at the fuel rich condition" or "An air-fuel ratio sweep was performed to identify the best operating air-fuel ratio". This suggests more of a method or process rather than a result or a condition. Got any more ideas?
Jeannette Eckel (asker) Mar 28, 2008:
Es geht im Groben darum, den besten Zünszeitpunkt mit Hilfe des Ionisationsstroms zu finden. Dieses konkrete Diagramm 14 stellt auf der y-Achse die Ionisationsspannung und auf der x-Achse den Kurbelwellenwinkel dar.
Tilman Lichter Mar 28, 2008:
I think this is about the different readings on an air/fuel ratio gauge (i.e. voltmeter) with respect to different crank angles.
Konrad Schultz Mar 28, 2008:
Da stimmt etwas nicht, wenn man Krümmerwinkel und Kraftstoff/Luft-Verhältnis in einer Zeichnung in Zusammenhang setzt, hat dies nichts mit Spannungen zu tun.

I think that's it
