Definitions
- the invention relates to internal combustion engines, in particular internal combustion engines, in which fuel can be operated according to a predetermined injection profile with one or more pilot injections and one or more main injections.
- the present invention relates to measures for adjusting the injection profile in transient engine operation.
- the injection of fuel into the cylinder of an internal combustion engine can be carried out in one or more pilot injections and one or more main injections in accordance with a predefinable injection profile.
- the injection profile can be determined by maps depending on e.g. the current engine speed and the requested load of the engine are specified.
- the state variables of the air system of the internal combustion engine usually only follow the corresponding setpoint values of the air system control with a delay. Since the injection profile is usually changed immediately as a function of the requested load of the internal combustion engine, the injection profile is thus not ideally adapted to the delayed changing air system conditions and the resulting cylinder filling. This can lead to increased pollutant emissions. Disclosure of the invention
