Definitions

  • the invention relates to an ignition system for an internal combustion engine with the Features of the preamble of claim 1.
  • Such an ignition system is known in principle from DE 297 01 235 U. There It is about the problem of sealing the spark plug to the outside, when the in Cylinder head located spark plug / ignition coil unit with a high voltage supply is provided by a mounting hole on the cylinder head fitted cylinder head cover engages. In the known ignition system is a sealing body between the mounting hole and the unit provided.
  • the invention is based on the object, an ignition system of the aforementioned Art to create, in a structurally simple way, the risk of damage the electrical connection of the spark plug / ignition coil unit is eliminated.
  • the preferably made of elastic material molding is used in the first Line of the rotary position fuse of the ignition coil. This eliminates a special mechanical Load of the electrical supply for the ignition coil. Somehow is kind of rigid mechanical connection between ignition coil and spark plug not mandatory.
  • the correct rotational position of the ignition coil can by appropriate Shape design of the molding can be achieved. For example, one is enough simple marking, for example, with a reference mark on the edge the mounting hole then corresponds when the ignition coil in the correct Drehlage sits.
  • a constructive improvement of the invention is to the molding with to provide a boom, which over the clear cross section of the mounting hole protrudes and engages in a recording. It can by a shape design the ignition coil can be achieved that the ignition coil when properly Assembly pushes the molding into the receptacle. The correct fit of the molding and thus the ignition coil can thus be readily recognized.
  • the molded body 1 shown in FIGS. 1 to 3 consists of elastic material, e.g. Silicone. He sits between an unillustrated mounting hole of a Cylinder head of an internal combustion engine and also not shown Ignition coil, which is part of an ignition coil / spark plug unit (so-called single coil ignition system) is.
  • the molded body 1 consists essentially of a tube cylinder section 2 and is provided with a boom 3, with a groove 4 in a receptacle on the edge of the spark plug shaft 6 engages (not shown).
  • the molded body 1 further has a sealing labyrinth 5, which is in the form of a closed Circular channel 5 'has and over the circumference of the cylindrical portion of the second almost completely revolves. Closely adjacent to the circumference, the labyrinth 5 has a Inlet and an outlet opening. About the inlet air enters the Seal labyrinth 5, through the outlet opening, this air enters the interior of the Spark plug shaft 6. Moisture droplets floating in the air are in the air Round channel 5 'deposited and so do not get into the interior of the candle shaft 6th
  • the ignition coil is rotationally secured with respect to the molded body 1.
  • it has For example, a groove into which a corresponding, e.g. rib-shaped recess of the molded body 1 engages.
  • the mounting hole / spark plug well 6 and the rotational position assurance of the ignition coil with respect to Shaped body 1 is thus a rotational position secured arrangement of the ignition coil within reaches the mounting hole 2.
  • the electrical leads of the ignition coil are subject Therefore, even in long-term operation no special mechanical stress.
  • the ignition coil is only plugged and is supported solely by friction by the elastic material of the molding, supported.
  • the illustrated molding can due to its material and shape height tolerances to about 2mm while maintaining the labyrinth and sealing function. simultaneously there is a vibration decoupling of the coil, since no direct mechanical Connection between the coil and the cylinder head of the internal combustion engine consists.
