Abstract
A method for injecting fuel at at least two different high fuel pressures via injectors into the combustion chamber of an internal combustion engine. The fuel injection at the higher fuel pressure takes place by pressure-controlled features, during the fuel injection, at least one lower fuel pressure is generated. To that end, a fuel injection system has one local diversion unit for each injector, and the diversion unit can be activated or deactivated via a valve unit.
