Abstract:
An ionization detector that reduces the filtering effects of the ignition coil inductances by shorting an inductance of a primary winding of the ignition coil. The ionization detector includes a bias voltage source and an inductance control switch. The bias voltage source supplies electric voltage across an electric gap of a spark plug for detecting ionization within the combustion chamber. The inductance control switch is electrically parallel with a primary winding of an ignition coil and is operable to short an inductance of the primary winding.

Claim (Index 10):
A spark-ignition system comprising:\n a spark plug having an electrical gap and operable to generate an electric spark for igniting gas; an ignition coil including a primary winding and a secondary winding, wherein the ignition coil is operable to generate an electric current that arcs across the electric gap of the spark plug to generate the electric spark; an ionization detector sensing an ionization current after gases are ignited and including a bias voltage source and an inductance control switch, wherein the bias voltage source is electrically coupled to the secondary winding of the ignition coil and the inductance control switch is electrically parallel with the primary winding and is operable to short an inductance of the ignition coil; and a current sensor outputting a signal indicative of the ionization current flowing from the bias voltage source to the electrical gap, wherein the current sensor comprises a current mirror circuit.
