Abstract

PURPOSE:To properly detect leak or missparks as well as normal operation in the ignition system in such a way that a discharge voltage detector and a discharge current detector are installed on the secondary side of an ignition coil, and these output signals are given as input to a diagnosing circuit. CONSTITUTION:Signal (c') from a voltage detector 11 on the secondary side of an ignition coil 1, signal (e') from a discharge current detector 12 of an ignition plug 5, signal (g) which is generated when a magnet 10 of a rotor 3r meets a lead switch 9, and signal (a) which is generated at the connecting part of the primary side 1P of the ignition coil 1 to an igniter 2 are respectively given as input to a diagnosing circuit 13. Thus, in case where the signal (c') is not detected while an AND gate 410 is kept opened by signal (n) from a counter 330, high level of signal is given as output for the purpose of mis-spark signal coming from output (p) of the gate 410. Beside, in the event that while the gate 420 is kept opened, the signal (c') is detected and signal from the discharge current detector 12 is not detected, high level of signal is given as output for the purpose of leak signal coming from the output (q) of the gate 420.
