摘要： The invention relates to a pump/nozzle unit for delivering fuel (10) into a combustion chamber (12) of an internal combustion engine, comprising a fuel pump (14-22), which can be controlled and/or regulated and which has a control valve (22) with a valve needle (48) that is displaced by a piezo actuator (76). The comparatively short travel of the piezo actuator (76) is increased by a mechanical multiplication device (56, 58) to the extent necessary for displacing the valve needle (48). In order to avoid jeopardizing the pressure resistance of the control valve housing while yet providing the comparatively wear-resistant contact areas (80, 82) coming into contact with the mechanical multiplication device (56, 58), the invention provides that the control valve housing is made of a material having a comparatively lower basic hardness, for example, Ovako 677, and the contact areas (80, 82) of the control valve (22) are subsequently hardened by laser.

摘要： Ein Piezoaktor wird in einer ersten Betriebsart (B1) angesteuert durch getaktetes Zuführen einer ersten elektrischen Größe zum Laden oder Entladen des Piezoaktors unter Berücksichtigung mindestens eines Ansteuerparameters (P) des Piezoaktors. Der Piezoaktor wird in einer zweiten Betriebsart (B2) angesteuert durch ungetaktetes Einprägen der ersten elektrischen Größe zum Laden oder Entladen des Piezoaktors, und zwar mit einem vorgegebenen Verlauf der ersten elektrischen Größe, der im Wesentlichen unabhängig ist von einer Laständerung an dem Piezoaktor (1). Ein Verlauf einer zweiten elektrischen Größe des Piezoaktors wird erfasst während mindestens einer Messzeitdauer während des Einprägens des vorgegebenen Verlaufs der ersten elektrischen Größe. Der mindestens eine Ansteuerparameter (P) des Piezoaktors wird ermittelt abhängig von dem erfassten Verlauf der zweiten elektrischen Größe.

摘要： The invention relates to a method for pretreating a piezoelectric ceramic (1) and a method for adjusting an injection valve (7). The piezoelectric ceramic (1) is exposed to environmental conditions, leading to a reduction of polarisation and also a reduction of the length of the ceramic (1). The obtained length exhibits a greater long-term stability due to said adjusting phase. Consequently, the injection valve (7) can be re-adjusted before use. As a result, renewed adjustment thereof is required only after a long period in service.

摘要： A piezoelectric injector with a directly-actuated compound nozzle needle (5) for fuel injection in an internal combustion engine is disclosed. Both nozzle needles (15, 17) of the compound nozzle needle (5) are operated for opening the injection holes (16, 19) not as conventionally by means of a fuel pressure generated in the injector or by means of a servo valve, but rather directly by the piezoelectric actuator (3). The actuator (3) can thus advantageously directly control both nozzle needles (15, 17) by means of the amplitude of the control voltage applied thereto. In the inactive state, pressure springs (11; 20, 21) hold the injection holes (16, 19) of both stages closed.

摘要： The aim of the invention is to be able to detect the moment of impact of the valve needle (48) pertaining to a piezo control valve (22) of a pump-nozzle unit, when the piezo control valve (22) is closed and/or opened. To this end, the piezo voltage (u(t)) and/or piezo current (i(t)) are evaluated. Said evaluation can especially involve the identification of discontinuities and/or pulses during the course of the piezo voltage (u(t)) and/or the piezo current (i(t)). The detected moment of impact can advantageously be put in temporal relation with a known auxiliary variable (SOI, EOI), especially for regulation purposes.
