摘要： A method for operating an internal combustion engine and an internal combustion engine are described. In order to recognize and correct the drift in the amount of fuel injected over the service life of the injectors of the injection system of the internal combustion engine, multiple different corrective functions are used to establish corrected individual characteristics relative to nominal characteristics. Each offset of the corrected individual characteristic from the nominal characteristics is determined, offset curves are created, and the sections of the individual offset curves representing a minimal offset are used as control data for the amount of fuel to be injected, thus making it possible to always achieve overall optimal control with a minimal difference in the amount of injected fuel.

摘要： A method is disclosed for driving a piezoelectric actuator with a piezoelectric stack, which is operated as an actuating element of an injector. The piezoelectric stack is polarized during production by a polarization process initially with a first field strength, which results in a first length of the piezoelectric stack. According to the method, the piezoelectric stack is driven during operation at a second field strength, which is smaller than the first field strength, wherein a setpoint length for the piezoelectric stack is defined depending on the second field strength. In addition, a change in length caused by depolarization from the setpoint length of the piezoelectric stack is monitored. Then, when a predetermined threshold value for the change in length is reached, the piezoelectric stack is operated at a third field strength until the setpoint length for said piezoelectric stack is reached.

摘要： In a method for controlling a high-pressure fuel pump, which comprises an electrically controllable electromechanical inlet valve (2a) which is closed in the currentless state and is held in the closed state by the force of a spring (2b), an outlet valve (5a), and a displacement element (6), the inlet valve is operated in a self-controlling operating mode after a start command is present. In the self-controlling operating mode, the rail pressure is built without knowledge of the phase position of the displacement element. During the self-controlling operating mode, the phase position of the displacement element is determined. After the phase position of the piston or displacement element is determined, the inlet valve is switched over to a non-self-controlling operating mode.

摘要： When the internal combustion engine is in an injection-free operating mode, a selected injector is open for injecting a small fuel amount, whereby at least one working cycle with injector control follows or precedes one cycle without control, a differential of two subsequent segment times of the cylinder associated with the selected injector or another variable, that reproduces a temporal crankshaft angle speed modification, is determined as a measurement value respectively for the cycle with and without control, and a relation is formed between the values of the cycles with or without control and used to correct the injection characteristic curve. The engine operates with active ignition and the value for the cycle with control is tested by taking into account ignition faults and the relation is only used to correct the curve if the value in the cycle with control significantly deviates from the one without control.
