摘要： In a misfire detector device for use in internal combustion engine, a secondary circuit is provided to apply voltage to a spark plug of an internal combustion engine. A secondary voltage waveform detector is provided to detect a secondary voltage waveform. An integral circuit is provided to integrate the secondary voltage waveform detected by the secondary voltage waveform detector during a predetermined period including a part of sparking time period of the spark plug. A comparator is provided to compare the secondary voltage waveform with an integral value of the integral circuit. A misfire is determined by a relationship between the integral value of the integral circuit and the secondary voltage waveform based on an electrical resistance of a spark gap changing depending upon whether air-fuel mixture is normally ignited or not when the spark plug is energized.

摘要： A device for detecting the mix ratio of a composite liquid (6) has a transparent column (2) placed so that the bottom (22) of the column (2) is in contact with the liquid and a light emitting diode (3) disposed so that light therefrom is incident on one side of the column to pass therethrough so as to be incident on the interface (22a) between the bottom of the column and the mixing liquid. Light incident on the interface at less than the critical angle are refracted, while light is incident on the interface at more than the critical angle is totally reflected to escape from the other side of the column. A photodiode (4) is provided to receive the light beams escaping from the other side of the column and to generate an output. The effective photo-receiving area (41) of the photodiode is in the form of an inverted trapezoid to make the output from the photodiode more linearly dependent on the mix ratio.

摘要： An ion current detection apparatus which can detect ion current with a high degree of accuracy regardless of the presence of voltage damped oscillation and which does not cause contamination of a spark plug.
A spark discharge current Isp generated upon spark discharge of a spark plug 10 flows through a charge diode 28, a capacitor 24, and a diode 22, which form a closed loop together with the spark plug 10 and a secondary winding L2 of an ignition coil 12 that constitutes an ignition apparatus 2. As a result, a Zener diode 26 connected in parallel to these components generates a Zener voltage Vz and thereby charges the capacitor 24. When a preset wait time has elapsed after the ignition timing for starting spark discharge, the discharge switch 30 short-circuits the opposite ends of the charge diode 28 to discharge the capacitor 24, so that a high voltage having a polarity opposite that in the case of spark discharge is applied to the spark plug. An ion current Iio flowing at this time is detected by use of a resistor 22 connected in parallel to the diode 22.

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. A check diode is provided in a secondary circuit of the ignition coil to prevent a current flowing back to the ignition coil. The spark plug has a center electrode, a front end of which is projected from an insulator, and an outer surface area of the projected front end being 25 mm² or more. A sparkplug voltage detector circuit detects an attenuation time length of a sparkplug voltage waveform presented subsequent to a time period predetermined after an end of a spark action of the spark plug. On the basis of the attenuation time length, a distinction circuit determines whether a misfire occurs in a cylinder of an internal combustion engine.
