Claim Text:
1. A method for adapting adaptation values for adaptation of fuel injection quantities of an internal combustion engine to which fuel is supplyable via a mixed operation of two injection types, the first injection type corresponding to an intake manifold injection and the second injection type corresponding to a direct injection, the method comprising: when an operating state of the internal combustion engine is within a first predefined range, setting a first adaptation value; when the operating state of the internal combustion engine is within a second predefined range that does not overlap with the first range, setting a second adaptation value; adapting (a) a first injection quantity specification according to which to operate the internal combustion engine by a first injection type, wherein the adaptation of the first injection quantity specification is performed using the first adaptation value and not using the second adaptation value, and (b) a second injection quantity specification according to which to operate the internal combustion engine by a second injection type, wherein the adaptation of the second injection quantity specification is performed using the second adaptation value and not using the first adaptation value; and controlling the internal combustion engine to operate at a same time with: wherein at least one of the first and second predefined ranges includes operating states in which fuel is supplied to the internal combustion engine via both the first injection type and the second injection type.
