Abstract:
1. An ignition device, comprising: at least three electrodes having electrode tips, said electrode tips being disposed in at least one of a combustion chamber and a pre-combustion chamber, said electrode tips being arranged to define a polygonal area disposed in close proximity to a location where fuel is injected; a source of electrical energy that supplies said electrodes with power, said electrode tips being arranged so that when electrical power is supplied directly to each electrode tip, an area of electrical ionization zone is formed; and a timing circuit for allowing the source of electrical energy to selectively supply power to each electrode, wherein said timing circuit includes a signal circuit for allowing at least one electrode to be supplied with power that is subsequently discharged to at least two other electrodes.
