Abstract

The invention relates to an internal combustion engine comprising a fuel supplying device. Said fuel supplying device comprises a low-pressure circuit provided with a low-pressure pump and a high-pressure pump that is coupled to the low-pressure circuit on the input side and transports fuel into a fuel accumulator. A fuel transporting flow of the low-pressure pump is corrected according to an actual and a previously pre-determined nominal value of the fuel pressure in the fuel accumulator.
