Abstract

An improvement on conventional internal combustion ignition systems, which improvement comprises a capacitor connected parallel to the secondary winding of the ignition transformer, and a bypass circuit through which energy stored in the primary circuit is conveyed around the high impedance secondary winding of the circuit transformer to the spark plug after the high voltage at the secondary winding has fired an auxiliary gap to complete the by-pass circuit. The energy originally stored in the primary circuit is discharged at the plug to produce a plasma jet ignition plume.
