摘要： A second recirculation passage recirculates blow-by gas at an upstream section, which is upstream of an impeller of a turbocharger in an intake passage. A first passage branches and extends from a downstream section, which is downstream of the impeller in the intake passage. A second passage that forms part of the second recirculation passage connects the first passage and the upstream section to each other. A third passage, which is provided separately from the second passage, connects the first passage and the upstream section to each other. A change mechanism changes, in different manners, the flow rate of compressed gas recirculating to the upstream section through the second passage, and the flow rate of compressed gas recirculating to the upstream section through the third passage.

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 variable valve timing mechanism of an internal combustion engine varies the valve timing by varying the rotation phase of the camshaft with respect to a reference rotation phase of the drive shaft of the engine. The mechanism has a first rotation member and a second rotation member. The first rotation member rotates in fixed synchronism with the drive shaft and has at least one recess therein. The second rotation member is located within the first rotation member and rotates integrally with the camshaft. The second rotation member has a vane within the recess. The vane is movable between two walls of the recess and divides the recess into first and second pressure chambers. Hydraulic fluid pressure causes relative rotation of the second rotation member with respect to the first rotation member by applying pressure to the first and second pressure chambers to move the vane. The mechanism further has a lock device. The lock device restricts the relative rotation of the second rotation member with respect to the first rotation member such that the vane is kept between the two recess walls when the engine is cranking. The lock device is released after the engine reaches a predetermined running condition.

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.
摘要翻译：在具有用于每个气缸的多个电磁驱动阀的内燃机中，当在独立于排气冲程执行的排气再循环期间所需的EGR量Er相对较小时，通过仅驱动第一排气回流模式进入第一排气再循环模式每个气缸排气阀。用于以单阀驱动方式实现所需EGR量Er的打开阀持续时间Td1长于以双阀驱动方式相应的打开阀持续时间。因此，即使要求的EGR量Er较小，如果Td1> a，则可以实现“模式1的单阀驱动”。也就是说，可以减少仅允许窄范围的控制的模式2中进行控制的事件。因此，即使要求的EGR量Er小，也能够防止控制性的劣化。
