Definitions

  • ABSTRACT An ignition distributor for sequentially directing the ignition spark energy produced by an ignition coil to the spark plugs of an associated internal combustion engine.
  • An ignition spark energy conductive circuit connected to the secondary winding of the ignition coil, is in arc-gap relationship with the distributor output circuits through which the ignition spark energy is conducted to the respective spark plugs of the engine.
  • a rotatable member of insulating material having one or more areas through which ignition spark energy may be conducted to one of the output circuits at a time, is disposed within the arc-gaps and rotated by the distributor shaft.
  • This invention is directed to ignition distributors and, more specifically, to an ignition distributor of the type in which a rotatable member of insulating material, having one or more areas through which the ignition spark energy may be conducted, is disposed within arcgaps between an ignition spark energy conductive circuit and each of the distributor output circuits and rotated in timed relationship with the engine.
  • Future internal combustion engine ignition systems for motor vehicles may be required to deliver higher ignition spark energy with longer burn time, possibly 40,000 volts as opposed to the 20,000 to 30,000 volts of present systems, to enable the firing of much wider gap spark plugs.
  • Experimentation with this high ignition spark energy has exposed severe problems. For example, the contactor between the high tension terminal connected to one side of the ignition coil secondary winding and the rotor of the distributor was rapidly deteriorated due to the higher voltage.
  • the increased ignition spark energy produced arcs over wider gaps inside the ignition distributor which resulted in an arc-over between the rotor contact and the wrong spark plug output circuit.
  • an improved ignition distributor for sequentially directing the ignition spark energy produced by an ignition coil to the spark plugs of an associated internal combustion engine wherein an ignition spark energy conductive circuit connected to the ignition coil secondary winding is in arc-gap relationship with each of the distributor output circuits and a rotatable member of insulating material, having one or more areas through which ignition spark energy may be conducted to one of the output circuits at a time, is disposed within the arc-gaps and rotated in timed relationship with the engine.
