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).

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： 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.

摘要： In a method and device for characterising the return stroke of injectors, in particular piezo-injectors of an internal combustion engine provided with a common rail system, when the internal combustion engine is switched off, a constant pressure is dropped in the rail, thereby making it possible to measure the rail pressure and to adjust the injectors by corresponding power. The actuating power is increased until a discontinuity in a temporal progression of rail pressure occurs. The actuating energy applied for said state and a pressure available in the make it possible to measure the return stroke of corresponding injector.
