Method and device for operating an internal combustion engine and internal combustion engine

摘要

A method and a device for operating an internal combustion engine and an internal combustion engine are described, the fuel being injectable directly into a combustion chamber in particular via at least one first injector and also being injectable into an intake manifold in particular via at least one second injector. For injection of fuel in a full-load operating state of the internal combustion engine, a first selection is made from the at least one first injector and the at least one second injector having a first metering range, including a full-load injection quantity required for the full-load operating state. For injection of fuel in a partial-load operating state of the internal combustion engine, a second selection is made from the at least one first injector and the at least one second injector having a second metering range, including the adjustment of a minimum fuel injection quantity required for operating the internal combustion engine. The first selection and the second selection are made differently, in such a way that only the metering range of the first selection includes the full-load injection quantity and/or that only the metering range of the second selection covers the minimum fuel injection quantity required for operating the internal combustion engine.
