When fuel is injected into a combustion chamber () of a cylinder () of an engine () of a vehicle (), the fuel is injected in the form of multiple jets () with the aid of an injector (). In this connection, a first plane is defined in which both the central axis () of the injector () and the central axis () of the cylinder () lie. Furthermore, a second plane is defined in which both the central axis () of the injector () and the surface normal of the first plane lie. The jets () are generated in such a way that for each jet pair, which is formed from two of the jets (), an angle between the projections of the two central axes of the two jets of the jet pair into the second plane is smaller than 50&#xb0;.

Method and device for injecting fuel into a combustion chamber

To prevent particle emissions, the start of injection of an internal combustion engine is controlled as a function of a detected dynamics of an operating parameter of the internal combustion engine. The dynamics is detected by comparing the temporal change of the operating parameter to a threshold value. The control may be carried out such that, in particular, a value of the start of injection, determined with the aid of a regulation, is frozen for a specific holding period following the detection of the dynamics.
