摘要： A method for introducing fuel into a combustion chamber of an internal combustion engine is provided, in which fuel is injected at variable metering directly into the combustion chamber by a first fuel injector on the one hand, and into an air aspiration channel leading to the combustion chamber by a second fuel injector on the other hand. To ensure a reliable cold start of the internal combustion engine when using regenerative fuels even at low temperatures, in the cold start of the internal combustion engine a partial quantity of the required overall fuel quantity is injected via the second fuel injector, this partial quantity being the particular fuel quantity that exceeds a maximum fuel quantity able to be injected via the first fuel injector.

摘要： In a method for operating an internal combustion engine, a setpoint fuel quantity to be injected is subdivided into a first fuel quantity which is to be injected into an intake manifold of the internal combustion engine, and a second fuel quantity to be injected directly into a combustion chamber of the internal combustion engine. The subdivision of the fuel quantity is performed as a function of a temperature that is characteristic for the operation of the internal combustion engine, e.g., in a start of the internal combustion engine, and the ratio between the first fuel quantity and the second fuel quantity is continually modified as a function of the temperature.

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.
