摘要： A fuel injection valve having a piezoceramic valve body, comprising a plurality of superposed ceramic plates each having one conductor layer on each side and voltage leads to the conductor layers. Each ceramic plate is arranged on a carrier plate. Between each unit, consisting of a ceramic plate and a carrier plate, an insulating foil is provided with conductor foils arranged on each side as conductor layers. Each insulating foil comprises two terminal lugs. Each insulating foil, in the region of a terminal lug, is laminated on one side with one conductor foil. The correlated termial lugs are connected in each case to an electrical contact for the correlated conductor foils.

摘要： A fuel injection valve wherein a reciprocable valving element is movable from closed to open position by a piezoceramic moving unit having at least two flexural resonators in the form of laminated packages of metallic carriers, ceramic layers and foil-shaped and/or ring-shaped conductors connected to the poles of an energy source in such a way that energization entails deformation of packages in opposite directions, namely the deformed packages have confronting concave or convex sides. This increases the distance which is covered by the valving element in response to energization of the packages.

摘要： A mixture control for an internal combustion engine with a lambda probe and with a memory device containing nominal values for the fuel supply dependent on operational values of the engine, as load, rotational speed and temperature. The mixture control renders it possible to optimize the consumption and/or emission, under consideration of the operating conditions, in the entire moving range of an internal combustion engine. The memory device comprises address positions selectable by the operating values of the internal combustion engine and also by the actual lambda value, and stores nominal values for the fuel supply in the form of a map for a characteristic field. The probe voltage and the internal resistance of the lambda probe are determined. A temperature-corrected signal denoting the actual value of lambda is generated by determining a correction value from two measuring signlas such as probe voltage and the internal resistance of the probe, and the signal denoting the corrected actual value is fed to the memory device as address signal.
