摘要： An ignition apparatus for an internal combustion engine is capable of avoiding mis-ignition even if subject to external disturbances when a fail signal is transmitted through a common signal line on which an ignition signal can also be transmitted. An igniter is connected to receive the ignition signal from an ECU, and includes a waveform shaper connected with the signal line and having an input connected in parallel to an input resistance so as to make a voltage at the input higher than a prescribed voltage when the ignition signal flows into the input resistance, and a pulse output circuit connected to the input and having an output for generating the fail signal into which a secondary coil current is converted. The pulse output circuit adjusts a fail signal current such that the voltage at the input when the fail signal flows into the input resistance becomes less than the prescribed voltage.

摘要： An ignition apparatus for an internal combustion engine is provided which is simple in the circuit arrangement and highly reliable in operation. An electromagnetic pickup coil generates an ignition signal having a magnitude proportional to the number of revolutions per minute of the engine in synchrony with the rotation thereof for controlling an ignition coil. A waveform shaper in the form of a comparator shapes the ignition signal from the pickup coil into a signal containing a pulse having a rising edge and a falling edge. An integrator integrates the ignition signal from the pickup coil to provide a rpm voltage representative of the number of revolutions per minute of the engine. A signal level controller controls the voltage level of the ignition signal based on the rpm voltage generated by the integrator. A current absorber absorbs from the ignition signal a current in accordance with the voltage of a power supply which powers the ignition coil. A switch turns off the current absorber when the shaped signal generated by the waveform shaper rises. A current-absorption suppressor suppresses a current to be absorbed by the current absorber in accordance with the rpm voltage generated by the integrator.
