Abstract
A dual ignition system is disclosed wherein adjacent first and second current interrupter means are provided for each cylinder on the ignition timing means for an internal combustion engine to furnish successive sparks during the power stroke by means of first and second distributor rotor arms which are secured in a fixed angular relationship to each other and which rotate in synchronism with the timing means to thereby more completely ignite the combustibles in said cylinder.
Claims9
In an internal combustion engine having a plurality of cylinders and reciprocating pistons therein arranged to sequentially have successive intake, compression, power and exhaust strokes;
- ignition means including a high tension current source, timing means having a first current control means for momentarily controlling current flow in the high tension source, and distributor means having a first distributor arm rotating synchronously with the reciprocation of the pistons and connected to said high tension current source and adapted to momentarily communicate a first spark to a spark plug in each cylinder just prior to the commencement of its power stroke;
- the improvement comprising a second current control means for each cylinder adjacent said first current control means for momentarily controlling said current in said high tension source a second time, and said distributor means having a second rotating distributor arm electrically connected to said first distributor arm for successively momentarily communicating a second spark to said spark plug in each cylinder at the commencement of said power stroke to more completely ignite combustibles in said cylinders.
A multiple spark ignition system for igniting the fuel charge in the power stroke of an internal combustion engine comprising in combination:
- an ignition means including a high tension current source;
- timing means having a first and second current control means for momentarily controlling current in said high tension current source to produce respective first and second sparks at a spark plug;
- and
- distributor means connected to said high tension source, said distributor means having right first and second radially extending distributor arms rotating in synchronism with said timing means to deliver said first and second sparks respectively at said spark plug to ignite said fuel charge during each power stroke of said internal combustion engine.
