Title: Ion current detector
Inventor: IKEUCHI MASAYUKI
IPC: F02P7/00
Filed: 1990-11-09
Abstract: PURPOSE:To obtain an ion current detector excellent in detectability by applying positive-polarity bias voltage to a spark plug. CONSTITUTION:At an ignition timing for an internal combustion engine, ignition high voltage arises in the secondary winding 1b of an ignition coil 1 and discharge occurs between electrodes of a spark plug 4 to ignite and fire mixture. At this time, the combustion of mixture involves electrolytic dissociation to create ions. With the movement of electrons due to positive-polarity bias from a power source 9, an ion current flows in a passage via a diode 12, but the electrons have greatly smaller mass and faster moving speed than positive ions, so that a great amount of ion current is obtained. Voltage developed in an output terminal 10 by the ion current can be detected to identify the combustion of mixture. It is thus possible to obtain excellent detectability.
