摘要： A motor vehicle alternator connected to an output shaft of an internal combustion engine mounted on a vehicle, comprising a rotor made of a permanent magnet for producing a magnetic field, an armature (stator) having a coil placed opposite to the permanent magnet rotor and a belt drive mechanism for connecting one of the permanent magnet and the armature to the output shaft of the engine to bring them into a relative rotation such that the armature relatively moves in the magnetic field produced by the permanent magnet. In the alternator, there is provided an axial displacement mechanism for displacing at least one of the permanent magnet rotor and the armature in an axial direction of the relative rotation, whereby a magnetic flux passing through the armature is changed. The axial displacement mechanism comprises a solenoid, a plunger housed in the solenoid to be movable when the solenoid is energized and a lever connected to the plunger at one end and to a carrier that carries the armature such that it pivots about a fulcrum to displace the armature in the axial direction of the relative rotation. Other types of the mechanism using a rack and pinion, etc., are used. The operation of mechanism is controlled such that a desired electric power is generated.

摘要： A system and method for detecting a failure occurring in an exhaust secondary air supply system of an internal combustion engine. A conduit is connected to the exhaust pipe to supply secondary air to the exhaust pipe to promote oxidization of the emissions in the exhaust gases. A valve is provided in the conduit for opening/closing it. The failure of the valve is detected by operating the air pump to supply the air in the conduit, while closing the conduit by the valve. The air/fuel ratio is detected by an oxygen sensor installed downstream of the conduit to be compared with a desired air/fuel ratio. If the detected air/fuel ratio is leaner than a desired air/fuel ratio, the air flows to the exhaust pipe so that the valve is considered to be stuck to open. Alternatively, a pump current is detected and is compared with a reference value indicative of the current at no air flow. If the detected current is less than the reference value, the valve is considered to be in failure. Moreover, the movement of a valve member is sensed to detect whether the valve is stuck to close.
摘要翻译：一种用于检测在内燃机的排气二次空气供给系统中发生的故障的系统和方法。导管连接到排气管，以向排气管提供二次空气以促进废气中的排放物的氧化。管道中设有阀门，用于打开/关闭阀门。通过操作气泵来检测阀门的故障，以便通过阀门关闭导管时在管道中供应空气。空气/燃料比由安装在管道下游的氧传感器检测，以与期望的空气/燃料比进行比较。如果检测到的空气/燃料比比期望的空气/燃料比更稀，则空气流向排气管，从而认为该阀被打开。或者，检测泵电流并将其与表示无气流的电流的参考值进行比较。如果检测到的电流小于参考值，则认为阀门处于故障状态。此外，检测阀构件的移动以检测阀是否被卡住以关闭。

摘要： A control system for controlling an alternator driven by an engine, for generating electric power, has a changeover switch for selectively switching destination of electric power generated by the alternator to a plurality of electric loads having respective different load voltage values. An ECU controls switching operation of the changeover switch and controls the alternator electric power, according to a direction in which the changeover switch has been switched. The ECU detects voltage of the alternator electric power when the destination of the alternator electric power is to be switched from a first electric load having a higher load voltage value of the plurality of electric loads to a second electric load having a lower load voltage value of the same, and causes the changeover switch to switch the destination of the alternator electric power from the first electric load to the second electric load after it is determined that the voltage of the alternator electric power has been changed from a predetermined higher voltage value to a predetermined lower voltage value.
