Ignition system for internal combustion engine

摘要

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.

主权项

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; and a 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.
