  • Connector
    Publication number: 20040070204
    Abstract: The invention relates to a connector (3) for connecting a flow pipe leading to an internal combustion engine of a motor vehicle to a feed pump. Said connector comprises an elbowed connecting sleeve (7) which can be rotationally fixed in various angular positions in a receiver (6). Said connecting sleeve (7) is positively fixed in the receiver (6) by a catch means (9). In this way, the forces acting on the flow pipe are kept at a distance from a seal pertaining to the connecting sleeve (7).

  • Method for operating a diesel engine
    Publication number: 20030182934
    Abstract: The invention relates to a method for operating a diesel engine in which an air ratio (&lgr;) of the fuel which is to be burnt and of the combustion air supplied is set by a control unit (14) according to predetermined values. When a value (15) which is predetermined as a switching criterion is recorded, the control unit (14) switches to a special operating mode for regeneration of a catalytic converter (22) and sets the fuel/air ratio according to predetermined values for this operating mode.

  • Ejector pump
    Patent number: 6619927
    Abstract: An ejector pump for a delivery unit provided in a fuel tank of a motor vehicle has a nozzle produced integrally with a mixing tube. The mixing tube is shaped in the form of a tubular cylinder, so that virtually the entire ejector pump may be produced from plastic in a mold allowing axial demolding. The nozzle is therefore aligned,exactly with respect to the mixing tube. The ejector pump consequently has a particularly high efficiency.

  • Promoters for gene expression in caryopses of plants
    Publication number: 20030046731
    Abstract: The present invention relates to promoters which permit a caryopsis-specific expression or suppression of genes in genetically modified plants, to methods for the tissue-specific gene expression or gene suppression in plants, expression cassettes, recombinant vectors and host cells containing such promoters, to transgenic plant cells and plants transformed with said promoters, and to methods for generating such plant cells and plants.

  • Promoters for gene expression in caryopses of plants
    Publication number: 20030018994
    Abstract: The present invention provides promoters which bring about a caryopsis-specific expression of coding nucleotide sequences controlled by them, and to expression cassettes, recombinant vectors and host cells containing such promoters. Transformed transgenic plant cells and plants and methods for generating them, are also described.
