摘要： A control method for an internal combustion engine with at least one pressure accumulator in which fuel is stored under pressure, in order to supply pressurized fuel to at least one injection valve, and at least two high-pressure pumps which are connected to the at least one pressure accumulator in such a way that they can supply fuel to this at least one pressure accumulator either jointly or separately, with, if at least one condition is fulfilled, the high-pressure pumps being operated in a special operating mode in which only one of the high-pressure pumps supplies fuel to the at least one pressure accumulator, and with the high-pressure pumps being otherwise operated in a normal operating mode in which the at least two high-pressure pumps jointly supply fuel to the at least one pressure accumulator.
