ABSTRACT:
An apparatus for detecting a condition of burning in an internal combustion engine includes a spark plug and an ignition coil. The ignition coil has a primary winding and a secondary winding. The secondary winding is connected to the spark plug. An ion current sensing resistor is connected to a low voltage side of the secondary winding of the ignition coil for sensing an ion current. A diode is connected in parallel with the primary winding of the ignition coil. A switching element is connected in series with the primary winding of the ignition coil. The switching element is movable into and out of an on state. A suitable device is operative for resisting a current flowing through the diode when the switching element is in the on state.
