Abstract (en)

[origin: WO2007048676A1] In an internal combustion engine, the fuel is fed into at least one combustion chamber (12) via at least one injection valve (18). The inventive method comprises the following steps: a) a full injection is subdivided into a basic injection and at least one metered injection; b) the injection period of the metered injection is successively reduced while the injection period of the basic injection is increased such that a total injected amount determined from a valve characteristic remains the same.
