摘要： It has been difficult to manufacturing a cylinder head having an EGR gas cooling structure which has high cooling performance and can be easily configured. A cylinder head having an EGR gas cooling structure is configured in such a manner that a gas passage which guides to the air intake port side a part of the exhaust gas discharged from the exhaust port is disposed within the cylinder head water jacket to cool the exhaust gas flowing through the gas passage. The gas passage comprises a cooling section which makes contact with the coolant within the cylinder head water jacket, and also comprises a hollow pipe which has high-strength sections located at side portions of the cooling section and having higher strength than the cooling section. The high-strength sections of the gas passage are molded within and surrounded by the cylinder head.

摘要： An electromagnetically driven valve includes a valve element (14) that has a valve stem (12) and moves in reciprocating motion in a direction in which the valve stem (12) extends; a disc (30) that is interlocked with the valve element (14) at a driving end (32), extending to a pivoting end (33), from which a central axis (35) extends and around which the disc (30) oscillates; a coil (62) that oscillates the disc (30); a power supply (200) that supplies electric current to the coil (62); and an ECU (100) that controls the flow of current from the power supply (200) to the coil (62). A permanent magnet (300) is located on the outer side of the oscillating member, apart from the cores (61,161). During the initial period of operation of the disc, the ECU (100) controls the current so that it is supplied from the power supply (200) to the coil (62) in cycles, and in accordance with the voltage and temperature, controls the number of current cycles, the cycle length, and the value of the current.

摘要： An electromagnetically-driven valve includes intake valves that are provided in a gasoline engine and that are arranged side by side; a valve plate that connects the intake valves to each other, wherein driving force that is generated by electromagnetic force is transferred to the valve plate; and a changing mechanism that is fitted to the valve plate. The changing mechanism changes the valve drive state between the two-valve drive state, in which both of the intake valves are driven, and the one-valve drive state, in which one of the intake valves is driven and the other intake valve is stopped.

摘要： An electromagnetically-driven valve includes: intake valves that are arranged side by side; a disk that pivots using applied electromagnetic force to reciprocate the intake valves in a predetermined direction; and a connection member that connects the intake valves to each other. The connection member is provided with a needle bearing into which the pivot motion of the disk is input. The pivot motion of the disk causes a displacement between the needle bearing and the disk in a direction that intersects with the predetermined direction. An oil passage through which oil is supplied to the needle bearing is formed in the connection member.

摘要： The present invention relates to an electromagnetically driven valve suited for use in an internal combustion engine and aims at achieving appropriate operating characteristics in accordance with operating conditions of the internal combustion engine at the time of opening or closing a valve body. An armature(30) moving together with the valve body(18) is provided and upper and lower cores(30, 32) are disposed on opposed sides of the armature(30). The upper core(32) and the lower core(34) accommodate upper and lower coils(40, 42), respectively. An annular protrusion(36), formed not on the upper core(32) but on the lower core(34) only, has an inner diameter slightly larger than an outer diameter of the armature(30).

摘要： The arrangement has an exhaust valve driver using electromagnetic force to move the exhaust valve between open and closed positions. The driver contains an armature (74) coupled to the exhaust valve (43,44), an electromagnetic coil (80,84) for producing an electromagnetic force that acts on the armature, a valve spring for producing a force that acts on the exhaust valve and a controller. The controller controls the electromagnetic force that acts on the armature in the valve closing direction of combustion is interrupted if the valve is moving in the opening direction. An Independent claim is also included for a method of driving a valve arrangement.
