摘要：
An ignition apparatus (10) includes a central core (16) extending along a main axis (A), and a primary winding (24) disposed radially outwardly thereof. The ignition apparatus (10) further includes a secondary winding (30). The primary winding (24) has a greater axial length than the secondary winding (30), this additional axial length being implemented on the low-voltage axial end (42) of the ignition apparatus, relative to the main axis. The extended primary winding provides an increased leakage inductance spike, which may be used by an ion sense system to (i) obtain increased bias voltages, and, (ii) increase the effective turns ratio, thereby reducing the amount of wire required for the secondary winding.
