Ignition system for internal combustion engines
An ignition system for an internal combustion engine is described comprising: a driver circuits each operable in response to an ignition signal from an engine control unit; power transistors each responsive to one of the driver circuits to switch on and off a primary current in an ignition coil; a logic circuit for performing a logic operation on output operating states of the power transistors; and nonretriggerable monostable multivibrator means for receiving the ignition signal applied to each of the driver circuits as a first trigger signal and an output of the logic circuit as a second trigger signal whereby an ignition monitor signal having a predetermined time width is applied to the engine control unit when the first and second trigger signals are received.
