摘要： The invention relates to a sheathed-element glow plug for arranging in the combustion chamber of air compressing internal combustion engines. The inventive sheathed-element glow plug has a tubular metal housing in whose longitudinal boring a glow plug is fixed with a part of the length thereof in a sealed manner, whereby the glow plug has a thin-walled ignition tube which is closed with a base on the ignition tube end located on combustion chamber side. A resistor element which extends in an axial direction is arranged in the inner area of the ignition tube. Said element is comprised of a glow plug filament arranged on the combustion chamber side and a control helix arranged outside the combustion chamber. The control helix arranged outside the combustion chamber is provided with a connection part for the electric current, and the glow plug filament arranged on the combustion chamber side is electrically connected to the base of the ignition tube. The resistance of the control helix amounts to approximately 100 to 150 mΦ, and the current is supplied with clock pulses through the resistor element after the starting temperature has been reached.

摘要： A pencil type glow plug (10) to be arranged in the combustion chamber of air-compressing internal combustion engines has a tubular plug housing (11) in the longitudinal bore of which a pencil type glow element (16) is sealingly fixed over part of its length. An annular gap (21) is formed in a particular area located at the bottom of or facing the combustion chamber between the longitudinal bore (12) and the glow element (16) for thermally uncoupling the plug housing from the glow element.

摘要： The proposal is for a ceramic electrical resistor which can be produced by forming a ceramic from at least one silicon-organic polymer and at least one filler. The filler contains at least one high-melting-point conductive compound and the proportion of filler is 20 to 50 vol % in relation to the solvent-free polymer-filler mixture. The specific electrical resistance can be adjusted by means of the proportion of filler. The ceramic electrical resistor is particularly suitable as a heat conductor for pencil-type glow plugs.

摘要： The invention relates to a method (100) for machining the surface of a component, in particular an injection nozzle, said method including the method steps of pretreating (120) and/or cleaning (130) the surface of the component; forming (140) a silicon layer or a silicon-containing layer on the surface of the component by means of a deposition process at a first temperature; aftertreating (150) the surface with the layer formed thereon at a second temperature which, in comparison to the step for forming the layer, is greater than the first temperature in order to reinforce a diffusion of the silicon atoms out of the layer into the component surface and/or into a region near the component surface; and removing (160) the layer formed on the surface in order to expose the surface which has been changed during the formation (140) and aftertreatment of the layer.

摘要： The invention relates to a fuel injector (110) for injecting fuel into a combustion chamber of an internal combustion engine. The fuel injector (110) has at least one injection valve member (120), which is mounted in an axially movable manner in a valve body (114), for opening up and closing off at least one injection opening (124). The valve body (114) has at least one valve seat surface (122) at an end facing toward the combustion chamber. The injection opening (124) is provided in the valve seat surface (122). The injection valve member (120) has at least one valve sealing surface (126, 128, 130). The valve sealing surface (126, 128, 130) closes off the injection opening (124) in a closed state of the fuel injector (110). The fuel injector (110) also has at least one control valve (112) for hydraulically activating the injection valve member (120). The control valve (112) is designed such that, in a closed state of the control valve (112), substantially no axial hydraulic force acts on the control valve (112).

摘要： The invention relates to a device for determining various pressure levels on components (12, 13), connected to a test line (3, 14), for the purposes of testing. A signal converter (15) and an I/O unit (17) with serial electronic analyser (16) are integrated in the test line (3, 14). A first switching valve (2) and a second switching valve (5) are provided between a pressure source (1) and the component for checking (12, 13). By means of the above, the component for checking can be pressurised with a first pressure, a second pressure generated in a storage chamber (10) and the component (12, 13) pressurised with the second pressure.

摘要： The invention relates to a fuel injection valve, comprising a valve body (1), in which a drilling (3) with a conical valve seat (9) and at least one injection opening (11) are embodied. A piston-like valve needle (5) may be longitudinally displaced within the drilling (3) and cooperates with the valve seat (9) to control the at least one injection opening (11). A first conical surface (30) is embodied on the end of the valve needle (5) facing the combustion chamber and a second conical surface (32) arranged downstream of the above, whereby the first conical surface (30) has an apex angle (a1) smaller than the apex angle (b) of the valve seat (9), whilst the apex angle (a2) of the second conical surface (32) is larger than the apex angle (b) of the valve seat (9). An annular groove (34) runs between both conical surfaces (30; 32) the upstream edge of which serves as the seating edge (37) of the valve needle (5). At least one channel (20; 22; 23) runs off the annular groove (37) in the valve needle (5), which opens into that part of the outer surface of the valve needle (5) which is adjacent to the annular groove (37) and faces the injection openings (11).

摘要： A pencil type glow plug preheats the fuel-air mixture in the combustion chamber of a self-igniting internal combustion engine. The pencil type glow plug has a heating ceramic device and the resistance of the heating ceramic device is increased by reducing its cross-section in the area in which the fuel-air mixture is most accessible in the combustion chamber.
