  • Patent number: 7765980
    Abstract: The invention relates to a method for operating an internal combustion engine including a fuel-injection unit and a laser ignition-unit. According to the invention, during a compression cycle of the internal combustion engine, fuel is injected into the combustion chamber by means of the fuel-injection unit in such a way that an ignitable, round, flat mixed region of fuel and air forms on a plunger and a predetermined period elapses between the end of the fuel injection and the start of ignition in order to form the round flat mixed region. Ignition then takes place within the flat round mixed region by means of the laser-ignition unit.

  • Patent number: 7759825
    Abstract: In a rechargeable battery with a fuse for guarding against external short circuits, to make it possible to design the rechargeable battery independently of the possibly high normal continuous current, it is proposed that a signal connection existing between the rechargeable battery and a device provided for drawing current be utilized. To that end, a switch is provided, which is connected parallel to the fuse and which responds to certain electrical signals of the device. The signals can be delivered to the switch via the signal connection, so that the switch bypasses the fuse, once the signal connection is established and the aforementioned signals occur.

  • Patent number: 7735613
    Abstract: A self-boosting electromechanical friction brake, having a friction brake lining which is displaceable for actuation in the direction of rotation of a brake disk and which is braced via roller bodies on ramps of an abutment plate. When the brake is actuated, brake disk exerts a frictional force on the brake lining pressed against it, which urges the lining in the direction of an increasingly narrow gap between the ramps and the brake disk to exert a contact pressure that is in addition to that exerted by an actuation device to attain self-boosting. The roller bodies are supported fixedly and rotatably in bearing block on the brake lining whereby the roller bodies move in slaved fashion with the brake lining and always brace the brake lining at the same points.

  • Patent number: 7735315
    Abstract: The invention relates to a device and a method for producing an operating medium for a motor vehicle, especially for use in the exhaust gas post-treatment of the motor vehicle. According to said method, an operating medium is produced from an initial product and air using a catalyst device. Said initial product is heated and mixed with air and the heated mixture of initial product/air is fed to the catalyst device. A part of the initial product is converted to the gaseous phase by means of a preheating element and is entrained by a stream of air when leaving the preheating element, said stream of air leading to a combustion chamber. The method allows to efficiently produce an operating medium, especially a reducing agent for regenerating NOx storage catalysts.

  • Patent number: 7731304
    Abstract: The invention relates to an electronically regulatable vehicle brake system with traction control, in which a master cylinder is connected indirectly via a hydraulic unit to at least one wheel brake. The hydraulic unit has electromagnet valves and an externally triggerable pressure generator, for modulating the wheel brake pressure, optionally independently of the driver. For preventing wheel slip, the pressure generator is connected by its intake side to an intake conduit, among other things, that is controllable by an intake valve. To enhance the dynamics and improve the regulatability of a vehicle brake system, a self-aspirating pressure fluid storage unit is connected to the intake conduit and makes an aspiration volume available to the pressure generator.

  • Patent number: 7726283
    Abstract: The invention relates to a pressure booster arrangement for high-pressure injection systems or high-pressure injection system parts of internal combustion engines. A differential piston which operates with a large cross section in a medium-pressure reservoir and with partial cross sections is operative in terms of positive displacement in associated control and work pressure chambers that are separate from the medium-pressure reservoir and that are disposed in a guide body. The guide body guides the differential piston in its strokes and in turn axially adjoins a valve body. The valve body receives control and check valves for controlling communicating lines of the guide body and of the valve body for controllably connecting the control and work chambers to the medium-pressure reservoir or to a relatively pressureless fluid reservoir.
