초록 ▼

An ignition system for an internal combustion engine that utilizes a single primary coil and a single secondary coil to drive a pair of spark plugs. Current flowing in both a first direction and a second direction passes through the primary coil. The current flowing through the primary coil induces corresponding current in the secondary coil, which flows from the secondary coil to one of two spark plugs. Each spark plug is coupled to the secondary coil such that each of the two spark plugs receives current flowing only in a single direction. The current flowing through the ignition system can be from either a power source or created by the rotation of a flywheel having a series of magnet clusters.

1. An ignition system for use with an internal combustion engine having a flywheel with a plurality of magnets spaced around the flywheel having either a first polarity or a second polarity, comprising: a primary coil positioned adjacent to the flywheel, wherein a first current flowing in a first direction is induced in the primary coil when one of the magnets having a first polarity rotates past the primary coil and a second current flowing in a second direction is induced in the primary coil when one of the magnets having a second polarity rotates past the primary coil;a triggering device connected between the primary coil and ground, wherein the triggering device is operable between an open position and a closed position in which the trigger device selectively connects the primary coil to ground to allow the flow of the first and second currents through the primary coil only when the primary coil is connected to ground;a secondary coil positioned such that the first and second currents flowing through the primary coil induce corresponding first and second currents in the first and second directions in the secondary coil only when the primary coil is connected to ground, wherein the flow of the first and second currents in the secondary coil is controlled by the triggering device;a first spark plug positioned such that only the first current induced in the first direction in the secondary coil passes to the first spark plug; anda second spark plug positioned such that only the second current induced in the second direction in the secondary coil passes to the second spark plug. 2. The ignition system of claim 1 wherein the first spark plug is connected to the secondary coil through a first restrictor and the second spark plug is connected to the secondary coil through a second restrictor, wherein the first and second restrictors are positioned to allow only the first current to pass to the first spark plug and only the second current to pass to the second spark plug. 3. The ignition system of claim 2 wherein both the first and second restrictors are diodes. 4. The ignition system of claim 3 wherein the diodes are oriented opposite to each other. 5. The ignition system of claim 1 further comprising a controller having a first output coupled to a first side of the primary coil and a second output coupled to a second side of the primary coil, wherein the first and second outputs from the controller control the flow of the first and second currents through the primary coil. 6. The ignition system of claim 5 wherein the controller is operable to control the current flow through the primary coil to vary the timing of the induction of the first and second current in the secondary coil. 7. The ignition system of claim 6 wherein the timing is adjustable. 8. The ignition system of claim 1 wherein the triggering device is operable to control the current flow through the primary coil to vary the timing of the induction of the first and second currents in the secondary coil. 9. The ignition system of claim 1 wherein the triggering device includes a trigger coil positioned adjacent to the flywheel and spaced from the primary coil, wherein rotation of the plurality of magnets past the trigger coil induces a trigger current. 10. The ignition system of claim 9 wherein the trigger current is induced in the trigger coil at a delayed time from the induction of the first current in the primary coil.
