Abstract
A method and a device are described for controlling an internal combustion engine, particularly an internal combustion engine that has a common-rail system. At least one pump delivers fuel into an accumulator. A pressure in the accumulator is detected. A distinction is made between at least one first operating state and at least one second operating state based on at least one speed signal and/or one load signal. At least one first pressure-control device is used to adjust the pressure in the at least one first operating state. At least one second pressure-control device is used to control the pressure in the at least one second operating state.
