摘要： An ignition timing control apparatus for an internal combustion engine wherein an ignition timing 0 (N, Tp) of at least one cylinder of the engine is retarded (or advanced) by a little amount Aa to intentionary check the generation sensitivity of a knock detection signal, that is, the detection sensitivity of knocking, then a knock judging level is modified thereby to judge as to whether knock is produced or not on the basis of the modified knock judging level, in order to correct and control the ignition timing θ (N, Tp) of the engine. As a result, irrespective of the non-uniformity of properties of the knock detection device and an internal combustion engine due to the deterioration with age or manufacturing errors, correct judgement of knocking can always be insured.

The apparatus may further includes a pressure sensor (14) for detecting the internal pressure of an intake manifold. The control unit determines a secondary air flow rate (Qs) from a difference between a first air flow rate (Qa) measured by the air flow sensor when the secondary air is not being supplied from the secondary air introducing path to the exhaust gas path and a second air flow rate (Qb) measured by the air flow sensor when the secondary air is being'supplied, or a difference between an intake air flow rate (Qpm) of the engine determined on the basis of the internal pressure of the intake manifold detected by the pressure sensor and an air flow rate (Qhw) measured by the air flow sensor when the secondary air is being supplied. In the case where the determined secondary air flow rate is out of a predetermined allowable range, the secondary air supply device is judged as being abnormal.

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.

摘要： A diagnostic system in which the accuracy of the diagnosis of the deterioration state of a catalyst (40 in Fig. 1) in a catalytic converter (4) for cleaning the exhaust gas of an internal combustion engine (2) is enhanced without incurring a rise in cost. The temperature of the catalyst (40) is estimated using the operating-state signal (for example, the flow rate of intake air Qa or the width 120 of a fuel injection pulse) of the engine (2) by a diagnostic device (8). The conversion efficiency of the catalyst (40) calculated from the outputs of oxygen sensors (6a, 6b) is corrected using the estimated temperature by the diagnostic device (8). The deterioration state of the catalyst (40) is diagnosed on the basis of the corrected temperature by the diagnostic device (8).

摘要： A control apparatus for an automobile is provided with a system manager (1), which initiates and manages the operation of units for controlling and operating various devices and accessories installed in the automobile. The system manager (1) is coupled with a card unit (13), in which a card is inserted. Such a card has an identification code of a user and a code indicating that the card is registered in advance. The system manager (1) has a list of codes of cards registered. If a card inserted is confirmed to be correct and valid by the ID and the registration code, the system manager (1) executes a predetermined processing operation and produces a set-up instruction signal. Upon receipt of this set-up instruction signal, the control units (19-35) for the devices and accessories are initiated.
