Definitions

  • the present invention essentially relates to a device for fitting and holding in an engine cylinder head at least one assembly formed by an ignition coil associated with a spark plug.
  • such an assembly can equip each cylinder of the engine and makes it possible to dispense with the ignition distributor. It is particularly suitable for the case where the spark plug occupies a central position in the cylinder, as is the case in multi-valve engines where the valves are arranged around the spark plug.
  • the present invention aims to provide a system for holding a coil-spark plug assembly in a cylinder head, which is satisfactory in all respects.
  • the subject of the invention is a device for arranging and holding in an engine cylinder head at least one assembly formed by an ignition coil associated with a spark plug, in which the cover of the cylinder head has at least one knocked-out part forming a receptacle for the ignition coil which is held therein by a cap fixed on the cylinder head cover and covering said receptacle, characterized in that the cap has ribs coming from its inner face in contact with the ignition coil to maintain it in abutment on a shoulder of the receptacle by means of a support made of elastic material, interposed between the shoulder and the collar of the ignition coil.
  • an assembly E often called “single coil” consisting of an ignition coil 1 mounted on a socket 2 connected to one of the poles of the secondary of the coil and engaged on the tip of connection 3 of a spark plug 4, the assembly E being able to be fixed on the cylinder head C of an engine.
  • the coil 1 comprises a collar 5 formed by the stack of sheets of the transformer forming part of this coil.
  • the cover 6 of the cylinder head C of the engine comprises at least one knocked-out part forming a receptacle 7 for the ignition coil 1 and comprising an arrangement, such as for example a shoulder 8, receiving a support 9 made of elastic material, such as rubber, interposed between said shoulder and the collar 5 of the ignition coil 1.
  • This coil is kept applied in the receptacle 7 against the support of elastic material 9 by a casing, cap or the like 10 fixed on the cover 6 of the cylinder head and covering the receptacle 7 as well as the coil 1 housed in this receptacle.
  • This cap 10 has ribs 12 coming into contact with the ignition coil 1, more precisely with the upper part of the collar 5.
  • the casing or cap 10 which is preferably made of light alloy, will ensure, after fixing by the means 11, the maintenance of the ignition coil 1 in the receptacle 7 by means of the ribs 12, so that the support of elastic material 9 is compressed to obtain sufficient crushing, allowing said coil to be pressed against the ribs 12.
  • the contact of the ribs 12 with the coil 1 will advantageously allow the evacuation by conduction of the calories stored by said coil, so that the casing or cap 10 will then act, in a way, as a radiator.
  • a simple and effective fixing device has therefore been produced according to the invention which, inter alia, the advantage of being able to be used with an existing cylinder head, without modification thereof.
