摘要： In an internal combustion engine comprising a valve operating system connected to a pair of intake valves and arranged to open one of the intake valves only in a very small amount such that the one intake valve is brought into its substantially inoperative state, in a suction stroke mainly in a low speed rotation region of the engine, a fuel injection valve capable of injecting fuel toward a pair of intake ports independently corresponding to the intake valves, and a control means for controlling the operation of the fuel injection valve, the control means is arranged to control the fuel injection valve with a fuel injection completion time determined within a suction stroke, when the one intake valve is in the substantially inoperative state. This ensures that when the one intake valves has been brought into its substantially inoperative state, the injection of fuel by the fuel injection valve can be completed in the suction stroke, so that the injected fuel can be sequentially introduced into a combustion chamber in a condition of the other intake valve being open, thereby achieving an axially stratified air charge to provide an improved combustibility.

摘要： A SOHC type internal combustion engine includes a pair of intake valves and a pair of exhaust valves. The intake valve driving means comprises a plurality of rocker arms disposed adjacent one another, including a pair of driving rocker arms operatively connected separately to the intake valves and a connection switchover mechanism capable of switching-over the connection and disconnection of the adjacent rocker arms in accordance with the operational condition of the engine. The exhaust valve driving means comprises a pair of exhaust valve-side rocker arms operatively connected separately to the exhaust valves and disposed on opposite sides of the intake valve driving means in positions opposed to said cam shaft, respectively. In the intake valve driving means, the opening and closing mode of the intake valves can be changed in accordance with the operational condition of the engine by operation of the connection switchover mechanism, thereby providing an improvement in output from the engine. The intake valve driving means is constructed compactly by disposition of the plurality of rocker arms constituting the intake valve driving means adjacent one another in the positions opposed to the cam shaft, thereby enabling an effective and compact construction of the connection switchover mechanism provided in the intake valve driving means.

摘要： An electromagnetic actuator is equipped with two springs which act in opposite directions, and an armature that is connected to the springs and is supported in an unactivated state in a neutral position provided by the two springs. The armature is coupled to a mechanical element such as a valve of an engine. The actuator includes a pair of electromagnets that drive the armature between a first terminal position and a second terminal position, and a power supply device that controls the voltage supplied to the electromagnet attracting the armature to a constant voltage when the armature is driven from one of the terminal positions to the other terminal position. The voltage supplied to the electromagnets is maintained at a constant value and the larger current flows in the larger is the gap between the armature and the yoke and smaller is the counter electromotive force.

摘要： A core of a solenoid actuator is provided which is improved in durability, and at the same time ensures high energy efficiency of the solenoid actuator. The core of the solenoid actuator attracts an armature during operation of the solenoid actuator. A plurality of core plates are formed of a magnetically soft material and laminated in a predetermined direction orthogonal to a direction of attracting the armature to form a laminated stack. The core plates form magnetic circuits between the armature and the core plates themselves during the operation of the solenoid actuator. Two core holders formed of a non-magnetic material sandwiches the laminated stack of the plurality of core plates from opposite sides along the predetermined direction. The plurality of core plates are each coated with insulating film, which insulate adjacent two core plates from each other. Further, a rod formed of a non-magnetic material rigidly secures the plurality of core plates and the two core holders to each other to form a unitary assembly. The plurality of core plates are each formed with at least one projection projecting outward from a surface thereof and at least one recess formed in a reverse side of the at least one projection. The at least one projection of one of the each adjacent two core plates is fitted in the at least one recess of another of the each adjacent two core plates such that the each adjacent two core plates are inhibited from relative movement with respect to each other in the direction of attracting the armature.

摘要： A solenoid-operated valve for use in an internal combustion engine has a valve body movable into and out of abutment of an intake/exhaust port in the internal combustion engine to close and open an intake/exhaust passage in communication therewith, a movable plate connected to the valve body by a transmission valve stem, a first solenoid for magnetically attracting the movable plate to cause the valve body to close the intake/exhaust port, and a second solenoid disposed in confronting relation to the first solenoid with the movable plate interposed therebetween, for magnetically attracting the movable plate to cause the valve body to open the intake/exhaust port. A piston is movable in a cylinder in unison with the transmission valve stem until the valve body closes the intake/exhaust port when the first solenoid magnetically attracts the movable plate to position the valve body closely to the intake/exhaust port. The cylinder gradually discharges a fluid filled therein in response to movement of the piston, for thereby causing dampening or the transmission valve stem to reduce a speed at which the valve body closes the intake/exhaust port.

摘要： A valve operating mechanism for an internal combustion engine for varying the operation of the valve dependent on engine operating conditions. A first rocker arm movable to follow a first cam and a second rocker arm movable to follow a second cam corresponding to a higher speed operating condition than that of the first cam are pivotally supported on a rocker arm shaft. A first connection switching device capable of switching the connection and disconnection between the third and first rocker arms and a second switching device capable of switching the connection and disconnection between at least one of the first and third rocker arms and the second rocker arm independently from the first connection switching device, are disposed at locations displaced circumferentially relative to the rocker arm shaft. Thus, it is possible to dispose a trigger mechanism and to dispose3 roller followers coaxially with the connection switching device, while avoiding the increase in width of the three rocker arms along their swinging axes.
