Abstract: A method for controlling the injection quantity of a piezoinjector of a fuel injection system, which comprises a nozzle needle displaceable by a piezoactuator. Based on the instantaneous injection quantity, a selection is made among various control methods. In a ballistic injector mode, a first control method is carried out, wherein both a needle closing point in time is equalized and a needle travel time is also equalized. In a full stroke injector mode, a second control method is carried out, wherein a needle closing point in time is equalized, but the needle travel time is not equalized.

Abstract: A method for detecting error-containing components of a piezo-injector in an internal combustion engine fuel-injection system is disclosed. The piezo-injector has a piezoelectric actuator and an injection needle driven thereby, and is configured for operation in a partial-stroke mode and a full-stroke mode. First, the internal combustion engine is brought to a defined operational point. Then, the time for the injector needle to strike its stop when said injector needle is opened, as well as the time for the injector needle to strike its needle seat again when said injector needle is closed, are measured. The measured times are compared to normal values determined at the test stand. Parameter(s) for the fuel-injection system are calculated, using different calculation models, and the results are stored. Finally, the calculated parameters of the different calculation models are compared to norm values determined at the test stand, and compared to one another.

Abstract: A control apparatus for an internal combustion engine has an exhaust-gas turbocharger regulator which, as a function of a setpoint boost pressure and an actual boost pressure, determines a controlled actuating-variable exhaust-gas back-pressure. An exhaust-gas recirculation regulator determines, as a function of a setpoint air mass flow and an actual air mass flow, a controlled actuating-variable exhaust-gas recirculation mass flow. A first decoupling unit determines a decoupling mass flow in an exhaust-gas section. A second decoupling unit determines a decoupling exhaust-gas back-pressure. A first conversion unit determines a signal for the exhaust-gas turbocharger actuator as a function of the pilot-control actuating-variable exhaust-gas back-pressure, the controlled actuating-variable exhaust-gas back-pressure and the decoupling mass flow. A second conversion unit determines a signal for the exhaust-gas recirculation valve as a function of the pilot-control actuating-variable exhaust-gas recirculation mass flow, the controlled actuating-variable exhaust-gas recirculation mass flow and the decoupling exhaust-gas back-pressure.
