摘要： In a method and an apparatus which more accurately reach a predefined setpoint value of a combustion characteristic variable for an internal combustion engine (1) with an injection system (30), a first injection signal which triggers an injection of fuel into a combustion chamber (53) of the internal combustion engine (1) is generated using at least one injection signal parameter. A combustion signal which represents a combustion of the injected fuel is generated by a detector (40). The combustion characteristic variable is determined using the combustion signal. The injection signal parameter is corrected using a deviation of the combustion characteristic variable from a setpoint value, in such a way that the deviation of a second injection signal which is generated using the corrected injection parameter is reduced for an injection which is to be performed later.

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： Each cylinder bank of the internal combustion engine is assigned in each case one injection event memory (EES), an injection determining process (EEP) and an injection execution process (EAP). In the respective injection determining process (EEP), desired injection events (EE) are determined for the associated cylinder bank. These injection events are stored in succession in the respectively associated injection event memory (EES). In the respective injection execution process (EAP), injection events (EE) are retrieved in succession from the associated injection event memory (EES) and executed in a sequence in which they were stored in the associated injection event memory (EES) by the associated injection determining process (EEP) (FIFO: first in first out). The in each case next injection event (EE) is executed only after the end of an execution of the in each case previously executed injection event (EE).
