Werkstattpraxis Präzise Diagnose mit Fuel Trim

Gemischadaption (Fuel Trim): wir erklären, wie die Werte der adaptiven Kraftstoffanpassung erzeugt werden, welchen Einfluss sie auf die Kraftstoffeinspritzung haben und wie dieses Wissen bei der Diagnose helfen kann.

Betrachten wir zuerst die Festlegung der eingespritzten Kraftstoffmenge ohne Korrekturen, bevor wir uns mit den angepassten Werten der Kraftstoffeinspritzung beschäftigen. Der Fahrzeughersteller hat die erforderliche Kraftstoffmenge in verschiedenen Kennfeldern festgelegt, die im ROM-Speicher des Motorsteuergeräts gespeichert sind.
