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 1):
An ionization detector apparatus for detecting ionization of gases, the apparatus comprising:\n a coil having a primary winding and a secondary winding; a bias voltage source electrically coupled to the secondary winding, wherein the bias voltage source supplies electric voltage across an electrical gap by way of the secondary winding such that an ionization current flows across the electrical gap in response to ionized gas being present; an inductance control switch positioned electrically parallel with the primary winding of the coil and operable to short an inductance of the primary winding; 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.
