Abstract
A method for operating an internal combustion engine having a motor with cylinder and an injection system having a common rail and injectors for the cylinders. Each injector has an accumulator for holding fuel from the common rail. A multiple injection of fuel is performed during each working cycle of a cylinder, including injecting a first amount in a first injection and injecting a second amount in a second injection, and determining fuel pressure for the common rail and/or the accumulator. A fuel injection amount parameter is determined for the first injection; an individual accumulator pressure and/or a common rail pressure is determined for the second injection; and a fuel injection amount parameter is determined for the second injection. The individual accumulator pressure and/or the common rail pressure are/is considered for determining the injection amount parameter of the fuel for the second injection.
