Abstract

An ignition system for igniting fuel within an engine cylinder, comprising: at least one ignition plug disposed in the cylinder; high-voltage pulse generator means connected to he ignition plug for generating a pre-pulse of static charge within the cylinder so as to ionize the fuel in the en-gine cylinder and thereby increase conductivity thereof, the pre-pulse comprising a high negative voltage high frequency burst of full-wave rectified alternating current; high-current pulse generator means connected to the ignition plug for generating a high-current pulse within the engine cylinder so as to form a plasma adjacent the plug for initiating com-bustion of the fuel within the engine cylinder; and controller means for selectively enabling and disabling the high-vol-tage pulse generator means and the high-current pulse gen-erator means at predetermined times.
