摘要： A spark plug is proposed for internal-combustion engines, which is used for the reliable ignition of fuel-vapour/air mixtures, especially also for the ignition of weak fuel-vapour/air mixtures and at the same time is supplied with voltage pulses from a conventional ignition system. The spark plug contains an insulator in a sealed manner in a tubular metal housing, which insulator surrounds the centre electrode and a capacitor which can be discharged via the ignition spark gap; a preliminary spark gap is additionally preferably accommodated inside the insulator, which preliminary spark gap makes it possible to charge the capacitor to high voltage and to release the stored energy to the ignition spark gap in the event of electrical breakdown. According to the invention, at least two opposing electrodes are arranged at the same distance from the end section of the centre electrode on the ignition side; as a result of the high-energy starting phase of the ignition spark of such a spark plug, ignition sparks simultaneously jump across between the centre electrode and all the opposing electrodes, which ignition sparks together form a relatively large hot surface. Spark plugs according to the invention are particularly suitable for modern internal-combustion engines having precise fuel-vapour/air preparation and suchlike exhaust gas preparation.

摘要： PCT No. PCT/DE97/01704 Sec. 371 Date May 7, 1998 Sec. 102(e) Date May 7, 1998 PCT Filed Aug. 11, 1997 PCT Pub. No. WO98/12431 PCT Pub. Date Mar. 26, 1998A fuel injection valve includes a valve needle passing through the valve opening to the valve closing body arranged on the spray outlet end. A closing spring prestresses the valve needle in a direction opposite its opening direction aimed in the direction of spraying, so that the valve closing body is in contact with the valve seat on the spray outlet end when the fuel injection valve is closed. The armature is kept engaged and in contact with the valve needle by means of a bearing spring which acts in the direction of opening by means of a connecting piece arranged between the armature and the valve needle. The connecting piece includes a suitable insulation element for providing insulation against high voltage.

Date Mar. 26, 1998An internal combustion engine, for motor vehicles having a direct fuel injection and externally supplied ignition, which has at least one combustion chamber enclosed between a cylinder head and a reciprocating piston displaceable in a cylinder bore, the combustion chamber being closable by at least one inlet valve for air aspiration. To attain extensive homogeneity of the mixture formation in direct fuel injection that assures reliable, thorough combustion of the mixture, the combustion chamber is preceded at its upper end by a chamber, which opens toward the combustion chamber and has an inside cross section that is substantially smaller than the combustion chamber and increases steadily toward the combustion chamber. The injection and ignition take place in the chamber.

摘要： A spark plug for internal combustion engines ensures the formation of two spark paths. These two spark paths are a pure air spark which jumps over from electrode to electrode, and a creepage spark which emerges from the central electrode, creeps along the insulator and then jumps over at the point at the smallest distance between the insulator and the earth electrode. The spark plug includes a cylindrical metal tube which forms a housing and in which the central electrode is arranged, surrounded centrally by an insulator. The earth electrodes mounted on the metal tube are partially bent so that an obtuse bending angle of the bent-over part with respect to the part of the earth electrode which extends in the direction of the rotationally symmetrical longitudinal axis is produced.
