    摘要： A failure detecting system of an exhaust purification apparatus includes, a catalyst unit including an electrically heated catalyst and intervened in an engine exhaust path, an air pump supplying a secondary air to the engine exhaust path, a first electric current sensor detecting electric current value for the electrically heated catalyst, and a second electric current sensor detecting electric current value for the air pump. The electrically heated catalyst and air pump are supplied with current upon a cold start of an engine. Presence of failures in the electrically heated catalyst and air pump is discerned on the basis of the electric current value each of the first and second electric current sensors, and the detection of the current value of the first electric current sensor starts prior to the detection of the current value of the second electric current sensor.

    摘要： A failure detection system detects a failure occurring in an exhaust secondary air supply system of an internal combustion engine, and has a catalytic converter installed in an exhaust pipe of an exhaust system of the engine for reducing pollutants from exhaust gases emitted from the engine, a conduit connected, at one end, to the exhaust pipe at a location upstream of the catalytic converter and an air pump connected to an opposite end of the conduit for supplying compressed air in the conduit. The conduit is closed by the a valve which opens in response to the negative pressure and a second valve which opens in response to the conduit pressure. In the system a first prescribed level and the second prescribed level are set and two pressure switches are provided for generating output at the levels. A failure occurring in the air pump and the valve is detected based on operation of the air pump and the output of the pressure detectors. Alternatively, the failure is detected by changing the timing of the termination of the air pump and closing of the second valve while using one switch and the second prescribed level. The system is simple in configuration.

    摘要： A control system controls an alternator driven by an internal combustion engine, for generating electric power. A changeover switch selectively switches the destination of electric power generated by the alternator to a plurality of electric load groups having respective different load voltage values, each electric load group having at least one electric load. An ECU controls switching operation of the changeover switch and changes output voltage from the alternator between a plurality of different predetermined voltage values corresponding, respectively, to the plurality of electric load groups, according to a direction in which the changeover switch has been switched. When switching of the changeover switch has occurred, the output voltage from the alternator to be supplied to one of the plurality of electric load groups to which the destination of electric power generated by the alternator has been switched is controlled by the ECU in a manner such that the output voltage progressively changes to one of the plurality of different predetermined voltage values corresponding to the one of the plurality of electric load groups.
