摘要： An engine ignition device comprises a circuit which generates a bias voltage corresponding to the engine rpm and superimposes it on an ignition signal so that the closing rate of the primary power feeding circuit for an ignition coil is controlled, a switching operation level setting circuit for generating a set voltage which changes with the engine rpm at startup or idling, and a comparison circuit having a first input receiving the ignition signal and superposed bias voltage and a second input receiving the set voltage, and generating an inverted output. The magnitude of the set voltage is changed in response to the engine rpm between the starting time and the idling time such that when the engine is started, the potential difference between voltages at the input terminals of the comparison circuit, as determined by the bias and set voltages, assumes a first value smaller than the ignition signal voltage, and when the engine is idling, the potential difference assumes a second value smaller than the ignition signal voltage, but larger than the first value.

摘要： An ignition apparatus for an engine reduces the duty cycle of a power transistor circuit for controlling the primary winding current of an ignition coil over the entire operating range of the engine including low and high speeds. In one embodiment, a signal generator generates an alternating output signal which is fed through a resistor to a wave form shaper for comparison with a threshold voltage. As long as the signal generator output is higher than the threshold voltage, the wave form shaper generates an output pulse for controlling a conduction time of the power transistor circuit. When the engine is operating at low speeds, the pulse width of the wave form shaper output is reduced by partially absorbing the signal generator output by a current absorbing circuit which is disabled at high engine speeds. In another embodiment, at high engine speeds, a DC current is supplied from a DC power source to a signal generator via a resistor through a current supply circuit which is disabled by a switching transistor at low enging speeds. In both of the embodiments, the signal generator has one end connected to ground and the other end connected at a single external connection point with the wave form shaper through the resistor.

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.
