Abstract

A method for adapting a transition compensation based on a lambda value change for operating an engine, which includes a combustion chamber having a first inlet opening connected to a first intake pipe having a first injector. The chamber includes a second inlet opening connected to a second intake pipe having a second injector. During normal operation, a predetermined fuel quantity is injected, and this quantity includes a first and second fuel quantities to be injected respectively via the first and second openings. In a first step, the first injector remains closed, and in a second step, the first injector is opened again. In the second step, a first test fuel quantity is injected into the combustion chamber via the first opening and a second test fuel quantity is injected via the second opening, the first and second test fuel quantities making up the predetermined fuel quantity.
