Abstract
An apparatus for a distributorless ignition system which responds to an ignition signal pulse train which is related to the compression and exhaust strokes of an internal combustion engine. The apparatus includes at least one ignition coil having a primary winding, a secondary winding, and a core, wherein the primary winding and the secondary winding are wrapped about the core, and the primary winding has a first end and a second end; a pair of spark plugs for each ignition coil, wherein the spark plugs are connected between opposite ends of the secondary winding and electrical ground; and a circuit connected to the first end and the second end of the primary winding for directing electrical current through the primary winding in an opposite direction during each successive ignition signal pulse such that the spark plugs simultaneously fire after each ignition signal pulse. Preferably, the circuit for directing electrical current through the primary winding includes both a driver circuit and a control circuit. The driver circuit is connected to the primary winding and serves to direct and drive electrical current through the primary winding. The control circuit is connected to the driver circuit and serves to control and activate the driver circuit.
