    • F02P13/00—Sparking plugs structurally combined with other parts of internal-combustion engines

Definitions

  • the invention relates to an ignition device for a Internal combustion engine with an ignition coil with primary and secondary windings and coil core and a spark plug with a spark plug body and isolator.
  • Known ignition systems for an internal combustion engine exist essentially from an ignition coil, one starting from it Ignition cable, a spark plug connector that with the Ignition cable is connected, and a spark plug on which the Spark plug connector is inserted. Because of this training usual ignition systems result from several individual components there are numerous interfaces at which in a known manner High voltage flashovers and contact problems can occur. You can also use the spark plug connector, for example and the ignition lead will experience increased capacitive loads.
  • the object underlying the invention is accordingly in an ignition device of the aforementioned Art to create that without the known ignition systems necessary interfaces.
  • this object is achieved by that the ignition coil and the spark plug to a component are interconnected.
  • the required Preload force for sealing the ignition device on the engine compartment side can be achieved by a screwing device, with which the ignition device in the cylinder head of the internal combustion engine is screwed in.
  • this training is a defined correct placement the electrode arrangement in the combustion chamber. The mixture accessibility the spark gap can then be optimal in each cylinder to the mixture flow during assembly.
  • the ignition device comprises a spark plug part and an ignition coil part that becomes a component are interconnected.
  • the combustion chamber side arranged insulator 1 of the spark plug part centrally in a metallic body 2 arranged.
  • the metallic one Body 2 is connected to a metallic shell 3, the forms the outer shell of the ignition coil 4 of the ignition coil part, which essentially consists of a coil core 5, a secondary winding 6 and a primary winding 7.
  • the primary or part of the ignition device on the engine compartment is with a Screw-in device 8, e.g. in the form of a hexagon, bihex formed, and a screw thread 9 is on the combustion chamber side provided to mechanically ignite the igniter in the cylinder head to attach stably.
  • the metallic jacket 3 is inner-walled with a casting cup 14 made of a plastic material or provided with a plastic coating so that the Spark plug part and the ignition coil part with a plastic casting compound 15 can be poured out in a vacuum. If the metallic shell 3 has a longitudinal slot, is the Casting cup 14 necessary.
  • Fig. 2 shows a further embodiment of the invention Ignition device from a spark plug part and an ignition coil part, as already described with reference to FIG. 1 was and is shown in Fig. 1.
  • the combustion chamber side of the metallic body 2 formed without a thread and instead provided with a cylindrical socket 16, the opens into a conical sealing seat 17.
  • the ignition device is on the engine compartment side with a screw-in device 18 provided, via which the required preload force is generated can to the ignition device with the conical Seal sealing seat 17 pressure-tight on the combustion chamber side.
  • the advantage of the embodiment shown in FIG. 2 is that a defined correct position Introducing the spark gap, i.e. the electrode arrangement, is possible in the combustion chamber. Thereby the mixture accessibility the spark gap in each cylinder is optimal for the mixture flow be set and thus an ideal ignition be initiated.
  • Fig. 3 shows a further embodiment of the invention Ignition device in which a spark plug part and an ignition coil part in one piece with each other are connected.
  • a ceramic insulator 19 is designed that it is centrally housed in a metallic body 20 is.
  • the engine compartment side part of the insulator 19 is used as the bobbin 22 of the secondary winding 21 of the ignition coil.
  • the axial bore of the insulator 19 is dimensioned so that a Coil core 23 and an ignition pin 24 and a center electrode 25 can be introduced.
  • the embodiment is the primary winding 26 outside arranged to the secondary winding 21.
  • the outer shell the ignition device consists of a metallic jacket 27, which is connected to the metallic body 20.
  • This in Fig. 3 illustrated embodiment of an ignition device is with a plug connection on the combustion chamber side and a screw-in device 28 on the engine compartment side.
  • Fig. 4 shows a fourth embodiment of the invention Ignition device with a one-piece design Insulator 30, the insulator of the combustion chamber
  • the spark plug part forms the function and on the engine compartment side a coil can for the ignition coil part.
  • Combustion chamber side is the ceramic insulator 30 in a metallic Body 31 added.
  • the part of the isolator on the engine compartment side 31 is in the form of a cup 31a so that an ignition coil with primary winding 32, secondary winding 33, Coil core 34 and bobbin 35, 36 is received therein.
  • the electrical contact between the ignition coil part and the Spark plug part goes over a sleeve 37 and an ignition pin 38, which is arranged in the combustion chamber-side part of the insulator 31 is.
  • the firing pin 38 and one also in the isolator 30 arranged center electrode 39 are by means of an electrical conductive glass melt 40 in the combustion chamber area of the ceramic insulator 30.
  • a screw-in device 41 is provided, which ensures that the ignition device is mechanically stable can be introduced into the cylinder head.
  • Combustion chamber side on metallic body 31 is sealed on a conical Seal seat 42.
  • a metallic sheet 43 is introduced as a cup 31a.
  • the necessary pre-tensioning force for pressure-tight sealing of the Ignition device can, for example, in the form of a Union nut with screw thread for screwing into the Be formed cylinder head.
  • the electrode configuration of the spark plug part is like this trained to have a life expectancy of more than 200,000 km mileage of the one equipped with the ignition device Motor vehicle is ensured.
  • the radio link electrodes for example with a precious metal like platinum, Armored iridium etc.
  • the ceramic insulator is designed with spark gaps, for the long service life and good cold start properties to ensure.
  • the ignition devices described above can be used in all Internal combustion engines are installed, geometric installation conditions do not have to be considered.
