Abstract
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.
