摘要： A spark plug which has a capacitor located therein, connected in parallel to the main or ignition spark gap (13), additional includes a pilot or pre-spark gap (12) located within the insulator (18) of the spark gap, to control discharge of the capacitor (14) through the main spark gap (13). In accordance with the invention, the pre-spark gap (12) is located within a chamber (34) in the insulator which is filled with a pressurized gas, preferably nitrogen under pressure of between 2 to 100 bar, preferably 5 to 30 bar, with the electrodes (27, 27) defining the pre-spark gap being spaced, preferably, between about 0.1 to 1 mm from each other. Placing the pre-spark gap electrodes within a pressurized gas chamber increases the energy available at the main spark gap (13) for ignition even of very lean fuel-air mixtures. Preferably, an inductive-resistive circuit (15) is connected in shunt across the main electrode (13) to prevent arcing and glow discharges across the main spark gap (13) after the initial ignition spark.

摘要： The interior of a differential pressure cell is exposed to the pressure in the intake pipe of an internal combustion engine. An absolute pressure cell is exposed to the ambient air pressure. The movable membrane of the differential pressure cell carries a plate on which are mounted two permanent magnets whose North poles face one another. A Hall generator fastened to the center of the movable membrane of the absolute pressure cell moves in the gap between the two magnets. The effective magnetic field applied to the Hall generator thus varies with the relative position of the Hall generator and the magnets. Adjustment of the spring constants of the two membranes allows any linear combination of differential and absolute pressure to be formed. Embodiments of different complexity and different degrees of linearity are illustrated.

摘要： An electromechanical transducer for transforming pressure fluctuations into varying electrical signals, especially for use as the induction tube pressure sensor for an internal combustion engine. A Hall-effect sensor moves within a local magnetic field to detect changes in pressure which alter the configuration of a diaphragm or diaphragm bellows to which the Hall-generator is attached. In order to suppress temperature-dependent terms in the Hall voltage equation, the invention provides for periodically alternating energization of the electromagnets, i.e., for alternation or alternating shut-off of the magnetic field. The Hall voltages measured during the two states of the magnetic field are subtracted from one another, thereby eliminating the temperature-dependent term. A number of configurations of the transducer elements is presented.

摘要： To measure small displacements, for example displacement of a membrane under change of pneumatic pressure applied at opposite sides thereto, a ferromagnetic wire is stretched between a fixed support and the membrane. An exciter coil, connected to a source of alternating current of suitable strength cyclically reversely magnetizes the ferromagnetic wire. A pick-up coil is electromagnetically coupled to the wire to sense the change of magnetization thereof which will be in the form of sharp needle pulses as the magnetization of the wire changes, the pulse amplitude and pulse width being highly dependent on the strain in the wire and hence on the deflection of the membrane. The wire may be stressed under tension.
