Definitions

  • An ignition distributor device for use with vehicle engine ignition systems equipped with electronically advanced spark timing angle controllers has a stationary high tension distribution electrode, a plurality of stationary output electrodes spaced from the distribution electrode, and a rotary dielectric shutter element disposed between the distribution electrode and the output electrodes.
  • the shutter has a window therein dimensioned to permit conductive association of the distribution electrode with only one of the output electrodes at a time.
  • the output electrodes are readily removable from and insertable in the distributor cap and also provide a cable termination for the ignition spark plug cables received in the cap.
  • This invention relates to vehicle ignition systems, and, more particularly, to a novel ignition distributor device for sequential distribution of high tension ignition pulses from the secondary winding of an ignition coil to the respective ignition firing devices of a multiple cylinder internal combustion engine.
  • the conventional automotive ignition distributor employs a contact breaker assembly which is mounted on an adjustable timing plate within the distributor housing and is operated from a multiple-lobed cam on the distributor rotor shaft driven from the engine cam shaft.
  • the breaker points are connected in interrupting circuit relation with the ignition coil, which is connected through the ignition switch to the vehicle storage battery when the breaker points are closed. Deenergization of the coil produced by the opening of the breaker points causes the collapse of the magnetic field therein and induces a burst of high tension energy, which is supplied from the coil secondary through a rotary or sliding electrical contact in the distributor cap to the distributor rotor switch arm.
  • the latter is a blade-like electrode driven-by the rotor shaft past a circular array of stationary output electrodes, which are permanently affixed to and located in the distributor cap and are connected to the engine cylinder spark plugs in the order in which the plugs are to be fired.
  • Timing advance for changing engine speed is accomplished by a centrifugal type governor mechanism, which is located within the distributor housing and mechanically simultaneously adjusts the angular position of both the breaker operating cam and the distributor rotor blade or switch arm on the distributor rotor shaft.
  • Vacuum advance is accomplished by a vacuum actuator, which is operated from a source 'of engine vacuum, such as the vacuum advance port of the carburetor, and is coupled through a mechanical link to the distributor timing plate to adjust its angular position relative to the distributor rotor shaft.
  • a vacuum actuator which is operated from a source 'of engine vacuum, such as the vacuum advance port of the carburetor, and is coupled through a mechanical link to the distributor timing plate to adjust its angular position relative to the distributor rotor shaft.
  • the distributor rotor switch arm and breaker cam are set in a predetermined angular position relative to each other on the distributor shaft such that the high tension coil energy generated by the operation of the breaker points appears at the rotor switch arm when it is just opposite a stationary output electrode connected to a selected plug to be fired.
  • the modulation of the spark timing by the vacuum advance structure is of a non-synchronous character, in consequences of which the position of the rotor blade may be shifted slightly from or relative to the output electrode at the moment of transfer of the high tension energy to the output electrode.
  • the combined width of the distributor rotor blade and the facing electrode portion of an output terminal is made of sufficient arcuate extent so that the transfer of high tension energy will occur while some portion of the blade is still adjacent the selected output electrode.
  • the distributor cap is made of a diameter to provide sufficient spacing between adjacent output electrodes located at the outer periphery thereof to prevent arc flashover and misfiring from the wide bladed rotor switch arm to the next adjacent output electrode.
  • the present invention has for its general object to provide an ignition distributor structure specially suited for use with internal combustion engine ignition systems equipped with electronic or other spark timing advance controls which do not mechanically advance the distributor.
  • Another object is to provide an ignition distributor for an internal combustion engine in which the high tension energy from the ignition coil is supplied to the distributor input or distribution electrode through a stationary, non-rotating electrical connection.
  • a related object is to provide a high tension distribution electrode assembly for an engine ignition distributor using a stationary high tension distributor electrode and stationary output electrodes.
  • Another object is to provide an ignition distributor in accordance with the foregoing objects having a distributor cap and rotor structure of minimum size and dimensions.
  • Still another object is to provide a push-in, readily removable electrode terminal serving as an output electrode and terminal for the distributor and as a connector for a spark plug cable for an ignition distributor in accordance with the foregoing objects.

  • the shutter element 48 is the only rotary part of the high tension distribution apparatus of the present invention.
  • the electrically conductive rotor arm of the conventional distributor structure is the electrically conductive rotor arm of the conventional distributor structure.
  • the shutter element 48 is electrically and mechanically disassociated from the input coil terminal.
  • the shutter element is an integrally formed, one-piece, dish-shaped member molded of dielectric insulating material and has a circular plate portion 86, an axially extending annular flange or ring portion 88 having a cut out portion in the form of an elongated aperture or window 90 therein, and an axially centrally located hub portion 92.

As shown in FIG.
  • the rim portion 88 of the dielectric shutter 48 intervenes or is interposed between the aforesaid electrode elements 78 and 84 and prevents ionization and breakdown of the interelectrode air gap except in the region of the aperture or window 90 where the aperture or window in the shutter intervenes to expose an output electrode to an adjacently located one of the finger-like electrodes of the distribution ring.
  • the arcuate or circumferential extent of the shutter window 90 is less than the angular spacing between adjacent ones of the output electrodes.
  • the arcuate extent of the window 90 should accommodate the entire timing shift between the maximum retard and advance conditions of the engine spark timing control and is selected so that in the maximum retard condition of the engine timing, as typified by the position of the shutter in FIG. 3, the input electrode 84b next adjacent the window-exposed input electrode 84a will be spaced by the insulating portion of the shutter a sufficient distance from its associated corresponding output electrode 78b, to avoid flashover of energy around the leading edge 90L of the window to its associated corresponding output electrode 78b.
