摘要： An electromagnetically operated valve assembly (28) has a first solenoid (58) and a second solenoid (60). An armature (56) having a valve stem (54) coupled thereto is positioned between the first solenoid (58) and second solenoid (60). A controller (12) is coupled to the first solenoid (58), the second solenoid (60). A current sensor (49) is coupled to the first solenoid and generated a signal corresponding to the induced current in the first solenoid. The controller (12) changes a voltage applied to the first solenoid from a first polarity to a second polarity. The controller (12) is further configured to hold the voltage at the second polarity for a predetermined time period and a predetermined amplitude to decrease the induced current. The predetermined time period or the predetermined amplitude is determined based on the first signal.

摘要： A method for controlling movement of an armature for an electromagnetic valve actuator. The armature moves between pole faces of juxtaposed solenoid coils. Voltage applied to armature capturing coil is varied in a closed-loop fashion as the armature moves through a flux initialization phase, followed by an armature landing phase whereby a soft landing of the armature is achieved during valve opening movement and valve closing movement.

摘要： An electromagnetic valve actuator (EVA) for actuating movement of a valve in a vehicle engine includes a valve assembly operatively connected to the valve for movement therewith. The valve assembly includes a shaft connected to the valve. Two armature plates are operatively associated with the shaft, and each armature plate includes a permanent magnet. An electromagnetic coil is positioned between the two armature plates for selectively electromagnetically pushing and pulling the armature plates. Two springs are engaged with the two armature plates, respectively, for biasing the armature plates in opposing directions. The permanent magnets are operative to assist the electromagnetic coil in holding the valve in a desired position to reduce power consumption or assisting in repelling the armature for accelerating valve opening or closing.

摘要： An intake valve phase shift in multi-valve engines to enhance air-fuel mixing and optimum combustion at all operating conditions. The intake valve members are independently operated by electro-mechanical actuators or the like, and activated and deactivated by the electronic controller of the engine. A channel or passageway in a diverter member positioned between the two intake ports in the cylinder head allows air and fuel from a closed intake port to be diverted to an open intake port and thus into the combustion chamber. The passageway preferably has a configuration with a certain curvature, orientation and position relative to the diameter of the inlet ports. The curvature is about one-half the diameter D of the inlet port, the passageway is symmetrical from port to port and directs the fuel toward the opposite sides of the ports, and the passageway is positioned about D/4 from the valve seats.

摘要： An electromagnetic actuator 10 for opening and closing a cylinder valve 14. The actuator includes an opening coil 20, a closing coil 22, a magnetic armature 26 which is disposed between coils 20, 22 and which is fixedly attached to the stem or shaft portion 28 of valve 14, a pair of conventional valve springs 30, 32, and a pair of pneumatic dampers or air cushioning assemblies 34, 36. Pneumatic dampers 34, 36 are effective to selectively decelerate the moving components of the actuator as they approach their respective seats during valve opening and valve closing events, thereby substantially reducing noise and vibration harshness (“NVH”).

摘要： An engine is provided with a combustion chamber that is separate from the main cylinder displacement/swept volume area and mounted in a cavity in the cylinder head and having a connection between the two by a channel of small cross-sectional area providing high velocity flow of fresh air from the cylinder into the combustion chamber to aid in fuel evaporation and fuel-air mixing, thereby providing complete combustion wholly within the separate chamber. Only intake air is taken into the engine during the intake stroke. A separate valve is provided at the exit of the combustion chamber to the connecting channel for cold start operation, the valve remaining closed until the ratio between the pressures in the cylinder under compression and in the combustion chamber exceeds two, i.e., establishing sonic flow in the channel, whereby a rush of fresh air into the combustion chamber upon opening of the valve and injection of fuel and ignition thereof causes complete combustion wholly within the combustion chamber. The pockets of fresh air stored in the main cylinder dilute the burned gas during the expansion stroke of the piston in response to the intense vortex flow out of the combustion chamber to the main chamber therefor promoting post oxidation of any unburned hydrocarbons.
