摘要:
In an adaptation method of an internal combustion engine for optimized combustion, the actually supplied cylinder-specific air masses are determined by determining the change in speed of the internal combustion engine within a thrust phase and by assigning these changes in speed to the cylinder-specific compression phases 20. This enables the fuel quantity to be injected to be more precisely adjusted to the cylinder-specific air mass available.

A low computation method for operating auto ignition combustion engines, in which outputs, in particular a requested torque set point TQI_SP is directly linked to an injected fuel mass flow distribution, to the EGR rate and the air control by taking into account engine out emissions & drivability constrains by using a multi-objective optimization method. A method to monitor in the embedded controller the indicated torque, TQI is also proposed.

An electronic key for use with a vehicle locking system controls at least one of a door locking feature and an ignition lock feature on the vehicle. The electronic key has a transmitter/receiver for transmitting at least one coded operating signal generated by the electronic key and transmitted from the electronic key to the locking system to activate at least one function of the locking system upon positive evaluation of the transmitted operating signal by the locking system. Actuating members are provided on the key and operated by the user to cause the transmitter/receiver to transmit the coded operating signal, and the activating elements are also adapted for the user to enter an individual code. A circuit is provided for receiving the entered individual code and comparing it with a programmed individual code and, upon entry of the programmed individual code being detected, changing the key over from a first, activated state in which transmission of the coded operating signal is prevented to a second, inactivated state in which transmission of the coded operating signal is permitted.

A device for active rolling walking (1) includes a conventional upper shoe (2) used for fixing the device to the foot, which upper shoe can be made from leather, textiles or other natural or synthetic materials, and a specially constructed sole to force active, rolling walking to take place and can be adapted to all possible circumstances. The structure of the sole and the choice of material gives the user, when rolling, the feeling of walking bare foot in the sand with a trampoline effect.

An apparatus is described for needling a non-woven material with at least one needleboard (1) which is drivable in a reciprocating manner by at least one eccentric drive in the needle-penetration direction, which needleboard is linked to the eccentric drive via push rods (6) each displaceably held in a guide sleeve (7), which eccentric drive consists of two parallel eccentric shafts (2, 3) which are drivable in opposite directions and are provided with connecting rods (4), with the guide sleeves (7) being swivelably held about an axle (8) extending parallel to the eccentric shafts (2, 3). In order to provide simple constructional conditions it is proposed that the two eccentric shafts (2, 3) are provided with a different angular position (&phgr;) and that the connecting rods (4) of the two eccentric shafts (2, 3) extend in an inclined manner with respect to each other.

A rolling-contact bearing for a shaft journal wherein the outside diameter of the shaft journal is thermally insulated relative to the shaft through which a heat transfer medium flows. The bore of the inner race on the shaft journal is provided with a ceramic layer predominantly of zirconium oxide and a smaller among of yttrium oxide to reduce the heat transfer from the shaft journal to the rolling-contact bearing. The inner race also has lateral surfaces toward the elements securing the bearing on the shaft journal. Those lateral surfaces may be provided with a ceramic layer as well.

Headbox of a paper machine and a process of supplying a material suspension, The headbox includes at least one material suspension supplying system, and a headbox nozzle that includes a first dividing wall having a machine width and a second dividing wall having a machine width. The first and second dividing walls are arranged to form a first path in which a total nozzle cross-section steadily and continually decreases in a material flow direction and to form a second path, arranged to follow the first path, in which a total nozzle cross-section continually increases in the material flow direction. The process includes includes accelerating the material suspension along a first path having a total nozzle cross-section that steadily and continually decreases in a material flow direction, and decelerating the material suspension along a second path having a total nozzle cross-section that continually increases in the material flow direction. The second path is arranged to follow the first path.

An apparatus for needling a non-woven material is described, comprising at least one needleboard (1) which is drivable in a reciprocating manner in the needle-penetration direction (6) as well as in the direction of the passage (11) of the non-woven material, comprising an eccentric drive for the needleboard (1) which comprises two parallel eccentric shafts (2, 3) which are drivable in opposite directions and assume a different angular position (φ), and couplers (5) which connect the connecting rods (4) of the two eccentric shafts (2, 3) in an articulated manner and comprise a guide arm (8) which is rigidly connected with the same, and a lifting guide means (9) for the guide arms (8) which forms a swiveling axis (10) for the guide arms (8) which is parallel to the eccentric shafts (2, 3). In order to provide advantageous constructional conditions it is proposed that either the guide arms or the couplers carry the needleboard.
