ABSTRACT:
In a method, a computer program and a control unit for operating an internal combustion engine having an injection system, e.g., for a motor vehicle, in the injection system fuel is conveyed into a fuel accumulator by a metering unit and a high-pressure pump. The pressure in the fuel accumulator is recorded and controlled by control of the metering unit with the aid of the control unit. In order to consider also possible manufacturing tolerances of individual metering units in the control of the pressure in the fuel accumulator of such a system, which is already known as such, and thereby make the control more precise, an individual characteristic curve is provided for the actually used metering unit be ascertained and taken into account in the pressure regulation.
