    摘要： To provide an ignition device advantageous in cost and space by using an inexpensive small-sized Zener diode (23) having a Zener voltage lower than an induced voltage generated at a primary current supply timing, so as to prevent sparking of a spark plug (19) due to the induced voltage. An ignition device for an internal combustion engine, including a Zener diode (23) provided on the secondary lower-voltage side of an ignition coil (18). The Zener diode (23) comes into conduction at a voltage lower than an induced voltage generated at a primary current supply timing.

    摘要： An electronic control apparatus for use in an automobile has a base (14) of a good thermal conductivity having one side disposed in contact with engine cooling water. Semiconductor devices (8, 9, 10, 22, 90) are disposed on the other side of the base so that the semi­conductor devices are maintained at the temperature of the engine cooling water, whereby the influence of high ambient air temperature to the semiconductor devices is reduced.

    摘要： There is disposed a knock sensor for detecting a knock signal of an engine. The output of the knock sensor is applied to a bandpass filter for bandpassing only the knock signal. The output of the bandpass filter is applied to an automatic gain control circuit for variably controlling the gain of the knock signal. The output of the automatic gain control circuit is applied to an averaging circuit via a maximum clamp circuit. A comparator produces an output to an integration circuit of the next stage when the output of the bandpass filter becomes greater than that of the averaging circuit. An ignition control device for controlling the spark timing of an ignition coil ignites the ignition coil by the output from a pick-up coil and that of the integration circuit and delivers a feedback signal to the integration circuit.

    摘要： A prescribed threshold level Dth for misfire judgment for each cylinder is recorded in a misfire judgment level retaining means 102 of a misfire judgment processing section 100. A combustion state parameter operation means 106 measures revolution speed of a multi-cylinder engine for each cylinder, and attains as a combustion state parameter a differential in revolution speed between a specific cylinder and other cylinders. In a misfire judgment level correction means 104, a plurality of combustion state parameters concerning the specific cylinder is attained, and the above-mentioned threshold level Dth is corrected as a function of the parameter. A misfire judgment processing means 108 compares the combustion state parameter with the threshold level Dth and diagnoses a combustion state in the specific cylinder. Namely, the corresponding cylinder is judged to be misfire when the combustion state parameter of the specific cylinder exceeds the prescribed parameter.
