    • 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.

    • A fuel injection amount control system for an internal combustion engine includes an ECU which calculates a desired amount of fuel to be supplied to each combustion chamber in response to operating conditions of the engine, and calculates values of parameters indicative of fuel adherence characteristics of the interior of the intake passage in response to operating conditions of the engine. The ECU further calculates a first fuel amount which is directly drawn into the combustion chamber from a fuel amount injected by the fuel injection valve, and a second amount of fuel which is carried off the wall surface of the intake passage due to evaporation and drawn into the combustion chamber, based upon the values of the parameters. The ECU calculates an injection amount of fuel to be injected, by correcting the desired fuel amount, based upon the first and second fuel amounts. When the engine is in a predetermined operating condition in which convergence of the fuel injection amount calculated by the ECU to the desired fuel amount can be unstable, the value of at least one of the parameters such that the fuel injection amount stably converges to the desired fuel amount.

    • In a dual-fuel internal combustion engine which can selectively use gaseous fuel such as CNG or liquid fuel such as gasoline, a pair of intake passages are independently connected to a combustion chamber of the engine, and a gaseous fuel supply device and a liquid fuel supply device are provided in the corresponding intake passages so that the liquid and gaseous fuels may not mix with each other when the fuel for the engine is switched over one from the other as they are introduced into the combustion chamber through different intake passages. Further, by switching the operating mode of the intake valve when changing the fuel, the configuration of the intake passage can be optimized for each fuel, and the timing and the lift of the intake valves may also be optimized for each fuel without complicating the control structure of the overall system. The present invention can improve the torque output and the emission property of the dual-fuel engine.
