    Abstract: 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.

    Abstract: The invention relates to a method for controlling a fuel injection apparatus, in particular a piezoelectric injector. Here, the fuel quantity which is injected into the combustion chamber is set by a mechanically actuable injector needle (1). Here, the injected fuel quantity depends on the pressure difference which can be set by the injector needle (1) between the spray-hole inlet and the spray-hole outlet.

    Abstract: A generally accepted and appropriate means to reduce pollutant emissions and consumption of passenger cars diesel engines is to apply multiple injection strategies. Assuming constant cylinder and bowl geometry and constant rail pressure the variation of the number of injections, injection quantity of each injection and separation between two consecutive injections are the major parameters which have to be optimised in order to fulfill both, the legislative emission limits and consumer requirements. A second, distinct approach to decrease pollutant emissions is to apply a single injection with a shaped injection rate. Ideally, rate shaping is achieved by a rise in injection pressure during one injection event, equal to that observed in cam controlled injection systems (e.g. Unit Injectors). For piezo driven common rail injection systems it might be possible to achieve similar effects by modifying the needle lift during an injection. The object of the present investigation is to compare and evaluate both methods in terms of pollutant emission, fuel consumption and robustness. For this purpose, experiments were carried out on single cylinder research engines. Multiple injection strategies with large hydraulic dwell times were compared with a short dwell setting simulating a “rate shaped” single injection. Rate shaping was implemented with a serial SIEMENS VDO piezo injector, performing multiple injections with hydraulic dwell times close to or equal zero.
