摘要： The invention relates to a control apparatus for controlling a solenoid valve that functions to displace one of an intake valve or an exhaust valve of an internal combustion engine. The object of the invention is to adjust, when a valve element connected to the solenoid valve is displaced between a valve-open position and a valve-closed position, the magnitude of an electromagnetic force displacing the valve element, to a controlled value based on a pressure acting on the valve element. The solenoid valve displaces the valve element (40) by a cooperation of resilient forces of an upper spring (104) and a lower spring (106) and electromagnetic forces of an upper coil (98) and a lower coil (100). In the control apparatus, a pressure acting on the valve element (40) is detected directly or indirectly. When the valve element is displaced from one of the valve-open position and the valve-closed position to the other position, the magnitude of an electromagnetic force to displace the valve element (40) to the other position is adjusted to a controlled value based on the valve-element pressure detected.

摘要： In an internal combustion engine having a plurality of electromagnetically driven valves for each cylinder, when an required EGR amount Er is relatively small during an exhaust gas recirculation performed independently of the exhaust stroke, a first exhaust gas recirculation mode is entered by driving only a first exhaust valve of each cylinder. An open valve duration Td1 for achieving the required EGR amount Er in a one-valve drive manner is longer than a corresponding open valve duration in a two-valve drive manner. Therefore, even if the required EGR amount Er is small, a “one-valve drive in pattern 1” mode can be achieved provided that Td1>a. That is, the incidence of performing the control in pattern 2, which allows only a narrow range of control, can be reduced. Hence, degradation of controllability can be prevented even if the required EGR amount Er is small.

摘要： A valve driving apparatus for driving an exhaust valve, using electromagnetic force provided in an internal combustion engine, the exhaust valve being movable between an open position and a closed position. An armature is coupled with the exhaust valve. An em coil generates an em force exerted on the armature. A valve spring generates a force exerted on the exhaust valve. A controller changes a normal state of movement of the exhaust valve to a state of movement that prevents the armature from bouncing off the em coil at the open position when combustion is suspended in the internal combustion engine.

摘要： An electromagnetic actuating system of an internal combustion engine is provided. The system can hold an armature in a fully closed position or a fully opened position when the engine is started while obviating a necessity of the initial actuation and effectively reducing power consumption of the system. The system includes an engine valve which functions as an intake valve or an exhaust valve of the internal combustion engine, an armature which moves with the engine valve, an electromagnet which attracts the armature in a direction of movement of the engine valve by being supplied with a current and a spring which presses the armature away from the electromagnet. A permanent magnet, which can exert a magnetic attracting force between the armature and the electromagnet, is provided. The system further includes a stop-time current controller which shuts off the current supplied to the electromagnet, after controlling the current supplied to the electromagnet until the armature is attracted to the electromagnet by the magnetic attracting force of the permanent magnet, when a request to stop the internal combustion engine is generated.

摘要： An electromagnetic actuating system having a valve member is provided. This system can improve a response of movement of the valve member while reducing power consumption of the system. The electromagnetic actuating system includes an armature which moves with the valve member, an electromagnet which attracts the armature in a direction of movement of the valve member by being supplied with a current, and a spring which presses the armature away from the electromagnet. A permanent magnet which can exert a magnetic attracting force between the armature and the electromagnet is provided. A current controller supplies a release current to the electromagnet so that magnetic flux is generated in a direction opposite to a direction of magnetic flux generated by the permanent magnet when the armature is released from the electromagnet. The valve member functions as an intake valve or an exhaust valve of an internal combustion engine, and the current controller controls an amount of the release current in accordance with an operating state of the internal combustion engine.

摘要： A control apparatus for a solenoid-operated valve that functions as an intake or exhaust valve of an internal combustion engine includes a lower spring biasing a valve body of the valve in a valve closing direction and upper and lower coils disposed above and below an armature for generating electromagnetic forces to move the valve body in the valve closing and valve opening directions. After a request for closing of the valve body is made, command currents are supplied to the upper and lower coils in suitable timing to increase the speed at which the valve body is seated against a valve seat. As the valve body rotates about its axis due to the action of the lower spring in the course of moving toward the valve seat, it is possible to crush and remove carbon between the valve body and the valve seat without causing local wear of the valve body.

摘要： A valve driving apparatus for driving an intake and an exhaust valve uses electromagnetic force and is provided in an internal combustion engine. Each intake and exhaust valve is movable between an open position and a closed position. The valve driving apparatus includes an intake armature coupled with the intake valve, an exhaust armature coupled with the exhaust valve, an intake valve opening spring for generating a force exerted on the intake valve in the direction of the open position of the intake valve, an intake valve closing spring for generating a force exerted on the intake valve in the direction of the closed position of the intake valve, an exhaust valve opening spring for generating a force exerted on the exhaust valve in the direction of the open position of the exhaust valve, and an exhaust valve closing spring for generating a force exerted on the exhaust valve in the direction of the closed position of the exhaust valve. A spring constant of the exhaust valve opening spring is greater than a spring constant of the intake valve opening spring. When the spring constant of the exhaust valve opening spring is high, an amplitude damping value of the exhaust valve is small. Since an amplitude damping value of the exhaust valve is smaller, an exciting electric current necessary for supplying to an exhaust lower coil can be restrained lower. Therefore, an electric power consumed by the valve driving apparatus can be saved.
