A method for monitoring the operation of sensors in an internal combustion engine includes providing reference values from output signals from a sensor. A sliding average (comparison value) is calculated from a relatively large number of reference values. The operation of the sensor is diagnosed as a function of the amplitude distribution of the reference values about the comparison value. If a malfunction is found, a fault message is transmitted to the driver and reversionary running of the internal combustion engine is started. An electric controller operating in accordance with the sensor is also provided.

The total ignition angle ZW(z) of each cylinder z is composed of cylinder-selective values basic ignition angle GZ(z) {determined by engine speed n and load L}, knock adjustment angle KNK(z), in addition to a first adaptation value AD1(z) and a second adaptation value AD2 common to all cylinders. AD1(z) is increased when KNK(z) is greater than a threshold DEC and is reduced when KNK(z) is lower than a threshold INC. The second adaptation value AD2 is formed as a function of the average value {overscore (AD1+L )} of the adaptation values of all cylinders.

An energy management system for a transport device, in particular for a motor vehicle running on fuel and electricity, includes an energy source, an intermediate energy store and an electric energy consumer, in particular an electric drive. Control and/or regulation of the provision of energy, which is dependent on information relating to future energy requirements and supplied by means of at least one part of the transport device, can be carried out by the energy management system by means of the intermediate energy store and/or the energy requirements.

A test rig for testing motor-vehicle assemblies includes a loading device for inducing vertical forces, lateral forces, longitudinal forces and braking or driving forces in the motor-vehicle assembly. The test rig includes a control device for controlling the loading device in such a way as to ensure that the vertical forces, lateral forces, longitudinal forces and braking or driving forces are induced in the motor-vehicle assembly according to a predetermined control loading programme. The control loading programme causes different loading cases of the motor-vehicle assembly, which are realistic in terms of the physics of driving, to be simulated repeatedly in a temporally consecutive sequence. The control loading programme is a standardised basic programme adapted, with the aid of vehicle-and/or axle-specific conversion values and test-rig-specific conversion values, to the given motor-vehicle assembly to be tested in the given case. Preferably, a modifying device is provided for adapting the motor-vehicle assembly to the standardised basic loading programme, whereby the modifying device enables adaptation of the basic loading programme in a particularly uncomplicated manner. The modifying device linearises the suspension spring characteristic of the motor-vehicle assembly.

A device has a generator for generating low-frequency pulsed electric currents and a transmitter coil connected to the generator for applying electromagnetic fields to a body region of a living organism and is designed for transporting ions from intra-corporal electrolyte liquids of the living organism into and through surrounding vessel walls and membranes such that the transmitting energy is selected to such a high value that the energy induced within the electrolyte liquid is greater than a thermal energy and is within a cell-specific amplitude window. Pulsed currents generated within the transmitter coil by the generator have the following properties: a) a basic current pulse of a first duration consists of a square current and a superimposed current increasing according to an exponential function; b a pulse interval subsequent to the basic current pulse having a second duration that is at least equal to the first duration; c) a basic frequency of the basic current pulse with the pulse interval is 100 to 1000 Hz; d) an amplitude of a sequence of the basic current pulses is modulated with a frequency of 0.5 to 35 Hz to yield a modulation amplitude; e) the sequence of the basic current pulse is emitted as a series for a period of 0.3 to 1.0 sec; and f) the series is followed by a series interval of 0.7 to 5.0 sec.

An inking unit for printing presses, preferably offset printing presses, can have a plurality of plate-inking rollers for inking a plate cylinder along with a multiplicity of inking rollers. The inking rollers can be positioned to supply ink flow, in at least two directions to the plate-inking rollers. The inking rollers and the plate-inking rollers can then form a closed chain of rollers, and can enclose a space therebetween. A measuring device can be provided to monitor the temperature of the air within this space, with measured values being used for control of the temperature of the inking unit.
摘要:
A wheel is provided for a commercial vehicle which comprises a wheel disk having bolt holes in the region of the wheel mounting face for attaching the wheel disc to a wheel hub flange or to a brake drum by way of wheel bolts and intermediate disks surrounding the bolt holes directly and concentrically and which by themselves provide a support surface between wheel mounting face wheel hub flange or, respectively, brake drum or dual wheel. The intermediate disks allow to avoid fretting corrosion in the support region of the wheel disc, stiffening of the wheel disk central region, avoiding of surface damage, and improvement of the bolting. The intermediate disks can be solidly attached to the wheel disk by way of adhesive disposed in between, by friction setting, or by casting.
