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： A knock control apparatus for an internal combustion engine includes a knock detector for extracting a vibration component superposed on an ion current, and waveform shaping it at a predetermined threshold value to generate a train of knock pulses (Kp) of which the number of pulses indicates a knock intensity of a knock generated in the internal combustion engine, and an engine control unit for counting the number of knock pulses (npn) in the knock pulse train (Kp) output from the knock detector. The engine control unit judges, based on the number of knock pulses (npn), whether or not a knock is occurring. The engine control unit performs a peak hold of the number of knock pulses to calculate the knock judgement threshold value (BGL) by multiplying the number of pulses by (&agr;). Thus, precision in knock judgement is improved by performing knock judgement based on a maximum value (MAX) of the number of knock pulses (npn).

摘要： A device for controlling knocking of an internal combustion engine featuring improved reliability by preventing signals of the knocking level from being erroneously detected as those of the noise level. The device detects an ionic current flowing through a spark plug, counts a signal of the knocking level from the ionic current, establishes an average knocking level from the signals of the knocking level and determines a background level from the average knocking level. A comparator judges the knocking state by comparing the signal of the knocking level with the background level. The device calculates the control quantity of the engine based on the operation conditions and the result of judgement of knocking. The device further judges a transient state and decreases the average knocking level depending upon a transience judgment signal in order to maintain a background level in a transient state at an optimum value.
