  • Patent number: 11420251
    Abstract: A casting mold for a crankcase of an internal combustion engine includes a water jacket core which has a frame core and a cooling duct core. A land core is provided which is designed and positioned in such a way as to form a cooling duct in an inter-cylinder land of a crankcase. The land core is retained in the frame core and is, or can be, centered using a top core.

  • Patent number: 10673341
    Abstract: The invention relates to a combined transformer for an LLC resonant converter. The combined transformer includes a primary transformer winding configured to generate during operation a first magnetic flux, which forms a first magnetic circuit. The combined transformer also includes a resonant inductor having a winding, wherein the resonant inductor is configured to generate during operation a second magnetic flux, which forms a second magnetic circuit. The primary transformer winding and the winding of the resonant inductor are arranged with respect to one another such that at least one first part of the first magnetic circuit and at least one second part of the second magnetic circuit run on a magnetic path common to the first part and to the second part. The invention also relates to an LLC resonant converter with such a combined transformer.

  • Patent number: 7490527
    Abstract: A control system for an automatically shifting transmission is described. A direct upshifting or downshifting starting from the automatic mode is permitted, by using a corresponding programming of the electronic control device when a certain selecting device is operated, without transition into the manual mode taking place. A gear change following this upshifting or downshifting is implemented, corresponding to the shifting logic of the automatic mode. In the case of a multiple operation, multiple direct upshifts or downshifts can also be permitted, without leaving the automatic mode.

  • Patent number: 7348093
    Abstract: The invention relates to a fuel cell stack which is composed of several individual fuel cells that are stacked on top of each other. Each of said fuel cells comprises a cathode-electrolyte-anode unit (7) and a perforated film (1) which distributes a combustible gas across the first electrode surface thereof, supports the cathode-electrolyte-anode unit (7), and is combined into a cassette (4) that is provided with a hollow space along with an additional structure (3). The combustible gas reaches the first electrode (7A) via said cassette (4).

  • Publication number: 20020177937
    Abstract: A temperature sensing device for an internal-combustion engine includes a carrier structure, a first sensor element accommodated on the carrier structure, a second sensor element also accommodated on the carrier structure, an engine air guiding device for feeding an engine intake air flow to the first sensor element, and a radiator air guiding device for feeding a radiator air flow passed through an engine radiator to the second sensor element. By way of a compact constructional unit, which can be preassembled, it is possible to centrally sense the temperatures of the two air flows. The obtained measuring signals can be coupled into a cable tree system provided on the vehicle side while the cabling expenditures are reduced.

  • Patent number: 5916298
    Abstract: A system, method, and display device for displaying an expected range of driving distances for a vehicle having a driving unit and an energy storage unit. A sensor senses an amount of remaining energy in the energy storage unit. An average minimum energy consumption rate and an average maximum energy consumption rate of the driving unit are determined based on at least one of (a) vehicle-specific energy consumption parameters; and (b) driver-specific energy consumption parameters. A minimum expected driving distance is calculated based on the sensed amount of remaining energy and the average maximum energy consumption rate. A maximum expected driving distance is calculated based on the sensed amount of remaining energy and the average minimum energy consumption rate. The expected range of driving distances defined by the minimum expected driving distance and the maximum expected driving distance are displayed on a display unit.
