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 19):
A method for operating a spark-ignition system, the method comprising:\n building magnetic energy between a primary winding and a secondary winding of an ignition coil; releasing the magnetic energy through the secondary winding such that an electric current arcs across an electrical gap of a spark plug to ignite an air-fuel mixture; shorting an inductance of the ignition coil after the air-fuel mixture is ignited; measuring an ionization current flowing from a bias voltage source to the spark plug, wherein the bias voltage source is electrically coupled to the spark plug by way of the secondary winding such that the secondary winding is disposed between the spark plug and the bias voltage source; and outputting a signal indicative of the ionization current flowing from the bias voltage source to the electrical gap.
