  • METHOD AND SYSTEM FOR INJECTING FUEL INTO INTERNAL COMBUSTION ENGINES
    Publication number: 20110253107
    Abstract: The invention relates to a method and to a system for injecting fuel into internal combustion engines, the injection taking place by way of an injection system and the fuel to be injected having an increased amount of fatty acids or fatty acid esters, particularly biodiesel. According to the invention, the components of the injection system coming into contact with the fuel are at least partially provided with a coating that has a low tendency for the agglomeration of fuel components, particularly fatty acids and fatty acid esters.

  • Arrangement with a coated piezoelectric actuator
    Patent number: 7990023
    Abstract: An arrangement is proposed for forming a piezoelectric actuator, which has at least one piezoelectric element that in each case consists of a multi-layer structure of piezoelectric-layers, wherein internal electrodes arranged between the piezoelectric-layers in the direction of the build-up of the layers of the piezoelectric element, have an electrical voltage of different polarity alternately applied to them. Around the piezoelectric element, or in the case of multiple piezoelectric elements positioned in series in the activation direction, around the piezoelectric elements, and at least partially around the actuator head and the actuator foot there is arranged a covering system made from at least one layer of an insulating material. The at least one layer encloses the joints between the piezoelectric element or elements and the actuator head and the actuator foot, forming a seal.
