Multiple Electrode Spark Plugs

Discussion in 'General Motoring' started by Anonymous via the Cypherpunks Tonga Remailer, Oct 13, 2003.

  1. No matter how many side (ground) electrodes there are, only one spark
    takes place during the high voltage discharge for the power stroke.

    Sparkplugs for cars usually have one electrode. But other designs
    have been marketed, notably those with two and three ground
    electrodes. The proper configuration is actually FOUR side
    electrodes, since all aircraft engine plugs have FOUR. The purpose of
    the multiple electrodes is to even out the erosion, thus extending the
    life of the plugs and assuring a fairly constant gap throughout its
    useful life. It is not to give "more power".

    The reason why FOUR electrode plugs are not used on cars is cost.
    They cost over ten dollars each. And for planes, its even worse, since
    there are TWO PLUGS per cylinder, each driven by an independent,
    self-powered magneto ignition. With two plugs and two mags, you
    actually get TWO SPARKS at the same time (actually staggered by 5
    degrees or so). Now if only Chrysler would put that in their cars
    instead of those idiotic computers and their 100 wire connectors to go
    wrong. Then, they could resume bragging about how Chrysler stands for

    OK, I am going to feed the troll.

    Most piston aircraft spark plugs have either ONE ground electrode
    for fine wire plugs or TWO for massive electrode plugs.
    On an aircraft engine BOTH plugs fire at the SAME time within +/- 1/2
    degree. If it is much more staggered than this the engine will not
    pass the mag rpm drop test.
    NONE of the auto manufacturers want to have computers controlling the
    engine. However after tons of money and man hours has been expended
    no one has found a lower cost way of meeting the "Government's"
    pollution standards.

    If you succeed then you will make a large fortune. GO FOR IT !!!!!!!!

    One of the problems with government is in order to keep the
    "burrowcrats" employed they must come up with NEW tighter regulations
    every few years. It is not long before you are paying 10 times the
    cost of removing the previous 99% of the pollutants on the last 1%
    You have to remember the government does NOT have to be efficient or
    make a PROFIT to stay in business! If the government needs more
    money they RAISE the TAXES!!!
