摘要： An ignition apparatus for an internal combustion engine is able to reduce generation of noise and energy loss due to wiring to a substantial extent. A capacitor 4 is connected at one end thereof to a DC power supply so as to be charged thereby, and at the other end thereof to an ignition coil 5. A switching element 9 is connected between the capacitor and a primary winding of the ignition coil to form part of a discharge path through which the capacitor discharges. The switching element is made conductive by means of an ignition or trigger signal which is generated by a signal generator in synchronism with the rotation of the engine, so that the charged capacitor discharges through the primary winding of the ignition coil. The capacitor, the ignition coil and the switching element are formed integrally with each other, housed in a single casing 13 and connected to each other without the use of a wire harness.

摘要： An ignition coil has an inorganic insulator material featuring a larger conductivity in the direction along the surface of the material than in the direction perpendicular to the surface of the material, between high-tension voltage components internal to a casing and conducting components internal and external to the casing. Localized discharge deterioration advancing from the high-tension components toward the conducting components is changed in its direction of advance to the direction along the surface of the inorganic insulator material, and is diffused accordingly. The resistance of the ignition coil against localized discharge deterioration is increased, and improved reliability in breakdown performance is resulted. This leads to a compact design.The casing and bobbins are constructed of mica sheet as inorganic insulator material using insert molding technique, and productivity of the ignition coil is improved.

The apparatus includes a bias voltage supplying means (9a, 9b) for applying a bias voltage (VBi) to the spark plugs (8a to 8d) by way of the high-voltage diodes (11a to 11d), an ion current detecting means for detecting ion currents (i) flowing through the spark plugs and an electronic control unit (2) for driving the ignition coil (4) and determining misfire event in the internal combustion engine on the basis of the ion current detection signal (Gia, Gib). The ion current detecting means includes a plurality of ion current detecting circuits for detecting ion currents in the engine cylinders belonging to a plurality of cylinder groups. The engine cylinders belonging to each cylinder group are so selected as not to be controlled in succession for ignition. In making misfire decision, the electronic control unit (2) makes use of the ion current detection signal derived from the ion current detection circuit means provided in association with the cylinder group which includes the engine cylinder currently subjected to the ignition control.
