摘要： A misfire detector for use in an internal combustion engine has an ignition coil including a primary coil and a secondary coil. An interrupter circuit is provided for on-off actuation of primary current flowing through a primary circuit of the ignition coil. A distributor has a series gap provided in a secondary circuit of the ignition coil, and a spark plug is adapted to be energized from the ignition coil through the series gap of the distributor. A voltage charging circuit works to electrically charge a stray capacity inherent in the spark plug immediately after an end of a spark action of the spark plug. A spark plug voltage detector circuit distinguishes the voltage waveform of more than a predetermined reference voltage level so as to deform the voltage waveform into output signals. On the basis of the width of the output signals, a distinction circuit determines whether or not the spark action ignites an air-fuel mixture in a cylinder of the internal combustion engine.

摘要： In a misfire detector device for use in internal combustion engine, an electrical interrupter circuit on-off actuates a primary current flowing through a primary circuit of an ignition coil to induce a sparkplug voltage which is applied to a multi-electrode type spark plug. A check diode or a series gap is provided in a secondary circuit of the ignition coil so as to prevent a current flowing back to the ignition coil. A sparkplug voltage detector circuit detects an attenuation time length of a sparkplug voltage waveform presented subsequent to a predetermined time period after an end of a spark action of the spark plug.

摘要： In equipment for recognizing misfire in an internal combustion engine, a first voltage waveform is obtained at an intermediate point (A) between a high impedance element (41) and a low impedance element (42). The first voltage waveform has a capacitive discharge component and an inductive discharge component during the spark and a voltage component after completion of the spark. The first voltage waveform is inversely amplified by a comparator (51) and divided by a shunt circuit (52) to obtain a second voltage waveform. In an integration circuit (53), a condenser (C1) is electrically charged by an output voltage from the comparator (51) to obtain a third voltage waveform. The second voltage waveform and the third voltage are compared by a comparator (54) to generate an output pulse. On the basis of the behavior of relatively short and relatively wide output pulse (d2, D2) and additional short output pulses (d3, d4) from the comparator (54), it is determined whether or not a misfire has occurred in the internal combustion engine.
