摘要： A method for detecting error-containing components of a piezo-injector in an internal combustion engine fuel-injection system is disclosed. The piezo-injector has a piezoelectric actuator and an injection needle driven thereby, and is configured for operation in a partial-stroke mode and a full-stroke mode. First, the internal combustion engine is brought to a defined operational point. Then, the time for the injector needle to strike its stop when said injector needle is opened, as well as the time for the injector needle to strike its needle seat again when said injector needle is closed, are measured. The measured times are compared to normal values determined at the test stand. Parameter(s) for the fuel-injection system are calculated, using different calculation models, and the results are stored. Finally, the calculated parameters of the different calculation models are compared to norm values determined at the test stand, and compared to one another.

摘要： The present invention combines bending mode mechanical (frm) and electrical (fre) resonances, whereby a relatively good efficiency can be achieved within a relatively broad frequency range (Δf3). An electrical resonance (frc) or mechanical resonance is designed to be situated in the same order of magnitude as another mechanical resonance (frm), but separated therefrom. Preferably, the separation (Δf2) is smaller than 2f1/Q1, where f1 is the resonance frequency for the resonance having lowest quality value, and Q1 is the corresponding quality value of the mechanical resonance. An electromechanical motor comprising a driving element and electrical resonance circuit according to the above ideas may comprise a double bimorph driving element having one single actuating point influencing a body to be moved. The double bimorph driving element is excited in bending vibrations perpendicular to a main displacement direction, whereby both tangential and perpendicular motions are created by bending mode vibrations.

摘要： The invention relates to a piezoelectric drive, containing a driven element (1) fitted with a friction layer (2) and at least one solid-state plate-shaped piezoelectric transformer (6) as driving element. The length of the transform (L) does not match its width (H). First and second groups of electrodes (12, 13) are provided on the surfaces (7) of the transformer. The first and the second groups of electrodes have areas with identical configuration on the opposite large-surface metallized surfaces of the plate-shaped piezoelectric transformer. Each group of electrodes forms at least one independent transformer of the acoustic waves that are not coupled to one another and which propagate along the long side of the piezoelectric transformer. Hence, the first group of electrodes (12) operates as longitudinal wave generator (17) while the second group of electrodes (13) operates as flexural wave generator (18) of the acoustic waves.

摘要： The invention described herein is a novel power circuit capable of electrically driving devices whose mechanical action is accomplished by induced strain transducers. The power circuit neither recycles nor dissipates the energy returned from the near lossless transducer, instead redirects power either to another transducer of the same type or to the transducer itself. The invention is based on a balanced capacitive loading method wherein the load itself acts as the energy storage element in the energy balance system. In the preferred mode, the circuit directs power to a symmetric couple where both loads in the couple consist of one or more transductive elements. The invention eliminates the need for a large power-supply bypass capacitor in driving reactive loads thereby reducing the peak power handled by the d.c. power section.
