摘要： An internal combustion engine, especially for vehicles, with direct fuel injection and applied ignition, presenting at least one closed combustion chamber (10) located between the cylinder head and a piston which can be moved into a cylinder bore (12). Said chamber can be closed by at least one inlet valve (15) for air intake. In order to obtain a highly homogenous mixture formation during direct fuel injection guaranteeing reliable combustion of the mixture, a chamber (17) opening out onto the combustion chamber (10) is placed in front of said combustion chamber (10) at its upper end. The internal diameter of said chamber (17) is substantially lower than that of the combustion chamber (10) becoming considerably larger as it approaches said chamber. Fuel injection and ignition occur in the chamber (17).

摘要： A spark plug has a tubular metallic housing, an insulator retained by the housing and an inner conductor arrangement embedded in the insulator and consisting of a connection bolt, an erosion resistance, a contact pin and a platinum central electrode. Four earth electrodes are secured to the housing, are bent towards the central electrode and project with their thickness over the insulator. The contact pin is coated and shortened in such a way that the erosion resistance projects as much as possible into the electrode gap. The platinum central electrode is shaped as a nail whose rear part has a smaller diameter than the front part which projects out of the insulator.

摘要： In ignition coils (11) with a secondary connector section (17) moulded on their casings (13) which transmits the high tension to the sparking plug (18) and consists of a fixed connection dome (19) and a sparking plug connector (21) movably connected thereto, attention must be paid to the correct position of the sparking plug connector (21) on the sparking plug (21) when fitting the ignition coil (11) on the cylinder head (12). To this end the sparking plug connector (21) has an annular collar (33) on its outer wall by means of which a centring sleeve (34) is interlocked. The centring sleeve (34) is frictionally and positively secured on the sparking plug connector (21) by a radial broadening of the annular collar (33). The outer shape of the centring sleeve (34) is matched to the inner shape of a plug recess (20) in the cylinder head (12) accepting the sparking plug (18), taking into consideration a certain movement play, so that the ignition coil (11) with the sparking plug connector (21) so supplemented can be properly guided and fitted on the sparking plug (18).

摘要： The proposal is for an electric spark-generating ignition device (10) designed especially for the ignition of gaseous fuels; it has a tubular metal housing (11) with securing means (12) on the outside. In the longitudinal drilling (18) of the housing (11) is fitted a tubular electrical insulator (27) with its section on the combustion chamber side sealed while its head (27/3) projects from the housing (11) on the connection side. The flange-like fixing (37) of the central electrode (34) passing through the central drilling (31) of the electrical insulator (27) is pressed on the combustion chamber side by a mechanically prestressed spring component (48) and is thus sealed in the central drilling of the electrical insulator (27). The spring component (48) is electrically insulated from the central electrode (34) and is supported on a component (20) secured to the housing (11). The central electrode (34) can form a single piece with the connecting piece (41) but both may be separate components and joined via an equalising spring (61) or an equalising spring (61') and an interference suppressor (70).

摘要： In the pressure sensor proposed, the pressure is transmitted through a diaphragm (14) and a punch (18) to a piezo-resistive sensor element (19). The sensor element (19) is printed on the substrate of a hybrid circuit (22) and comprises several resistance tracks (38, 39) disposed one above the other in layers, in particular in the form of a pyramid. This makes it particularly simple to transmit the pressure into the sensor in a controlled fashion. In addition, the hybrid circuit is located at one end of the punch stop (23). The compact mounting of the hybrid circuit (22) and piezo-resistive sensor element (19) gives a relatively small, inexpensive design, but a large and relatively error-free sensor signal.

摘要： A high-voltage switch, in particular for the ignition installation of internal combustion engines, is characterized by having an electronic, voltage-controlled high-voltage switching element that switches abruptly over from the blocking state to the conductive state at a preselectionable and predetermined voltage. Preferably, breakover diodes (8) connected in cascade are used which only transmit the voltage to the secondary winding (5) of an ignition coil (1) when the ignition voltage is reached at the ignition plug (7) of an internal combustion engine.

摘要： In a process for manufacturing a spark plug for internal combustion engines with at least two metal electrodes separated by a spark gap, at least one of the electrodes has a metallic coating of a highly abrasion-resistant material (noble metal). This material is deposited on the front surface of the metal electrode by laser radiation so as to form an alloy region of special design between the two parts. The special alloy region compensates for the different coefficients of thermal expansion of the electrode material and the metallic coating and effectively prevents depletion of the metallic coating.

摘要： The proposal is for harder-wearing spark plugs for an internal combustion engine. One feature concerns the burn-off resistor (13) of the plug which projects toward the spark path (20) of the plug in order that the current from the charge stored in the ignition capacitor is given off in a limited manner. A further modification relates to the diameter of the inner conductor (11, 16) which is reduced, thus making it possible to reduce the capacitance of the plug. A further modification concerns the electrode head (14) of the inner conductor (11, 16), where it is proposed to coat the electrode head (14) with a noble metal and to use a highly heat-conductive material for the electrode head (14) which acts as a heat buffer.
