Abstract: A process for the ignition of a regenerative soot filter adapted to be ignited in which the temperature, respectively, heat quantity necessary for the ignition of the filter is produced by charging a storage container located ahead of the soot filter or in connection with the soot filter which contains a hydride-forming alloy or a hydride-forming material. The necessary hydrogen is taken from a second storage container with a different alloy storing hydrogen, which is brought to a temperature by the exhaust gases so that a sufficient hydrogen pressure results therefrom. After the ignition, the second storage container is cooled off and the hydrogen is again conducted from the first storage container heated by the exhaust gases back into the second storage container so that the ignition operation can be repeated with renewed heating of the second storage container.

Abstract: A shifting arrangement for the shifting between a single-axle standard drive and an all-wheel drive, having a first clutch for the locking of a central differential gear and a second clutch for the connecting and disconnecting of one vehicle axle, actuated by first and second pressure medium control elements against the force of a spring and having a shift valve controlled by an electronic control unit, to either supply working pressure or relieve from pressure the control element. The shift valve can be controlled by the control unit in such a way that, when there is a shifting into the shifting step for the standard drive, the clutch torque of the clutch of the differential gear at least approximately increases only to the extent to which the clutch torque of the other clutch decreases. As a result, a sudden rise of torque is avoided at the vehicle axle that is driven in a standard drive.

Abstract: An ignition coil (1) for internal combustion engines comprises a magnetic core (4) of the core- of sleeve type, around the main core of which the primary and secondary winding being insulatingly enveloped with a cast material is arranged, the end regions of the main core being connected with each other via a magnetic path located outside the two windings, and having mounting members attached to the magnetic core (4) for mounting the ignition coil (1) to an automobile body. In order to bring the heating of the windings to an equal level and to reduce the heating of the windings, the mounting members are formed of a mounting plate (8) with mounting surface (9) and of at least one frame member (10, 11) integrally formed with the mounting plate (8) which envelopes the magnetic core (4) in a form-locking manner. The frame members (10, 11) can be expediently placed for mounting angularly on the ignition coil (1) and are pivotable in abutment with the surface of the magnetic core (4).

Abstract: A fuel-injection pump with a rotational speed governor for an internal combustion engine which for purposes of lubrication is connected to the lubricating oil circulatory system of the internal combustion engine. The lubricating oil which is thereby removed from the lubricating oil circulation is conducted by way of a pressure oil line and an inlet bore in the pump housing to a plunger cylinder of the injection pump and is controlled by the plunger sliding within the plunger cylinder by way of an aperture into a discharge bore terminating in the governor housing. From the governor housing, the lubricating oil flows over into the cam shaft space and is returned from the same by way of a return opening to the lubricating oil circulation of the internal combustion engine.

Abstract: A process is described for producing a diesel fuel/water emulsion for a diesel engine in which, as a function of the operating condition of the engine, water and diesel fuel are mixed at different quantitative proportions and supplied to the engine. The water and the diesel fuel separately are led practically to the intake side of the injection pump and are mixed only in the pump cylinder. The non-injected highly pressurized excess quantity of fuel is stored temporarily in an accumulator and is again supplied to the injection pump during the next intake stroke. The process makes it possible to produce a very fine water/fuel mixture and in addition to keep the volume of the fnished water/fuel mixture low, so that when the quantitative proportion is changed because of the inertia of the system, the new fuel/water mixture is available at the point of consumption (injection nozzle).

Abstract: A control device of a component vehicle route guidance system, the system comprising an on-board section having a navigation computer, and a vehicle-installed display for indicating the driver information data of the system. The control device is constructed as a portable hand-operated unit including a route computer, operating means and its own display, allowing the preselection of the route functions to be performed outside the vehicle. The device interfaces with the guidance system by plugging it into the on-board section in the vehicle. Various functions are enabled depending on which position the control device occupies in the on-board section.

Abstract: A self-optimizing control method for optimizing the fuel/air ratio under non-steady conditions in an internal combustion engine is described; in this method, a probe is provided both before and after the catalyst. Control quantities and the time during which the post catalyst probe shows an undesirable fuel/air ratio are stored for certain specified engine-operating conditions in the non-steady range. When the same engine operating condition is repeated, reference is made to the stored control quantities and time and the control quantity is varied in the direction of the correct fuel/air ratio. The time now obtained is compared with the stored time and, if the time has decreased, the new control quantity and the new time are stored. The control values are iteratively corrected by repeating these procedures, when the same engine operating condition reappears, until the time reaches a minimum.

To make it possible to actuate the lock easily and properly for safety purposes in spite of the high storage compartment located next to it, according to the invention, the top edge of the lock tongue and/or of the press button extends upwards relative to the load bearing deflection web of the lock tongue into the vicinity of the top edge of the storage compartment, center armrest or the like.

Abstract: A modulator for a vehicle with a power-assisted hydraulic multiple-circuit brake system, providing an output pressure to a static brake circuit that is proportional to the sum of the forces affecting a pressure modulator piston. These forces include a pedal pressure from the brake-pressure control device to a first driving pressure space of the modulator and booster pressure from the pressure of a proportional control valve to a second driving pressure space of the modulator, which shifts the modulator piston to decrease the output pressure space. Forces produced by auxiliary pressure in a counterpressure space shifts the modulator piston to enlarge the output pressure space. A control valve arrangement disconnects the second driving pressure space from the booster pressure and instead relieves pressure of the second driving pressure space in pressure-reduction phases of the antilock control.

Abstract: A hydraulic brake-power booster unit is provided for a vehicle having a dual-circuit brake system and an antilock system operating according to the drain principle. When the brake system is intact, the booster unit provides dynamic pressure to one of the two brake circuits and static pressure admission to the other. The pressure to the static brake circuit takes place by the separate-power-assisted shifting of an emergency piston. On one side, the emergency piston delimits an output pressure space to which the brake circuit that can be statically acted upon by pressure is connected. This brake circuit also remains operable in the case of a breakdown of the hydraulic power source only by the operation of the pedal and the resulting possible shifting of the emergency piston. A path transducer generates an electrical signal proportional to the position of the emergency piston.

Abstract: A thrust-control device for a motor vehicle having wheels driven on one axle, with a dual-circuit brake system having a tandem main brake cylinder and a brake booster supplied from a special auxiliary pressure source, with an anti-lock system having a brake-pressure medium return device, and with a pressure accumulator serving for thrust control, is extended for use on vehicles with a connectable or permanent all-wheel drive, to the effect that a stop valve is arranged in the brake circuit of the wheels of the further axle and there is a control valve controlling the accumulator pressure and acting on a pressure modulator, the pressure modulator influencing the brake pressure in the brake circuit of the wheels of the further axle when the drive of these wheels is connected and drive slip occurs. This simple extension requires no additional accumulator and makes it possible to preserve the independence of the brake circuits.

Abstract: A foot-supporting body in a motor vehicle is provided which is capable of supporting both feet of a passenger while reducing the intrusion depth, reducing the change in intrusion speed and performing deformation work. The foot-supporting body is made as a pure hard-foam moulded body which--arranged on the passenger/driver side of the end wall--extends beyond the left-hand foot-placement area at least as far as the area covered by the brake pedal. The inherent rigidity of the foot-supporting body, as viewed in the loading direction, which can be permanently deformed, is below that of the allocated area of the end wall. Polystyrene--or polyurethane--foamed plastic, with a lower volumetric-weight limit of about 20 g/dm.sup.3 is preferably used as the moulded body material in certain exemplary embodiments.
