摘要： In an automotive engine control apparatus used for a multi-cylinder engine where both an injection coil and an ignition coil are employed with each of multiple cylinders, abnormal states are systematically detected, while an injection system is mutually interconnected with an ignition system as to these abnormal states. The injection coils are driven via a first switch element by a microprocessor, and injection operations of these injection coils are monitored by a first detection circuit. The ignition primary coils are driven via a second switch element by the microprocessor, and ignition operations of these ignition coils are monitored by a second detection circuit. The microprocessor controls drive stopping means to perform a turn-out drive operation such that this drive stopping means stops both a fuel injection operation and an ignition operation of an abnormal-operated cylinder with respect to an abnormal state occurred in either the injection system or the ignition system. Also, abnormal-state storage operation by abnormal state storage means separatedly provided for the injection system/ignition system/cylinder system, which is derived from stopping of the drive operations, is prohibited by storage prohibiting means.

摘要： A control device of a fuel injection valve is capable of performing a stable fuel injection even if voltage variation takes place in battery, and performing evacuation operation against error in switching element or auxiliary power supply. The control device includes: an auxiliary power supply 6 for stepping up voltage of main power supply 1; a first switching element 20 for performing rapid power supply from auxiliary power supply 6 to electromagnetic solenoid 27; a second switching element 24 for performing continuous power feed from main power supply 1 to electromagnetic solenoid 27, and implementing ON/OFF control to perform holding power feed; a third switching element 26 for interrupting current of these power feeds; and a control device for controlling the power feeds. Power feed is normally performed in order of rapid power feed, continuous power feed and hold power feed.

摘要： A housing structure for vehicle-mounted electronic equipment according to the present invention is superior in heat dissipation, water resistance, heat resistance and vibration resistance. An electronic substrate is temporarily fixed onto an annular circumferential wall part of a cover made of fire retardant resin, and connector contact pins are soldered to the electronic substrate. The electronic substrate is fixed and held between a heat-transfer base and the annular circumferential wall part with screws, and heat generated by a heating part on the electronic substrate is transferred to the base and dissipated. The annular circumferential wall part has an annular groove in which a sealant is inserted, and the base has an annular protrusion snapped into the annular groove.
