Abstract

PURPOSE:To correctly detect the secondary side resistance of an ignition coil and prevent an electrode to be sooted, by installing the calculating circuit for the secondary side resistance of the ignition coil and the apparatus for preventing sooting of a spark plug, in the ignition apparatus of an internal combustion engine. CONSTITUTION:When an ignition signal generator 14 generates ignition signal in synchronization to an internal combustion engine, a power transistor 5 flows and cuts the primary current of an ignition coil 3 corresponding to the ignition coil signal. To the secondary side of this ignition coil 3, a spark plug 4 is connected. The secondary side resistance R of the ignition coil 3 is calculated by the secondary side current I2 of the ignition coil 3 which is detected through a secondary current detecting resistor 8 and the primary voltage V1 of the ignition coil 3 in a secondary side resistance calculating circuit 10. When the secondary side resistance R becomes above the standard value with which the electrode of the spark plug 4 becomes sooty, the comparison circuit 11 operates which generates sooting detecting output, and sooting is eliminated by a multi-ignition circuit 13. Thus, the secondary side resistance R is detected correctly, and electrode sooting can be eliminated.
