摘要： The present invention relates to a variable valve operating device and a valve opening amount adjustment method, and can accurately control the amount of in-cylinder air and the strength of a swirl flow. The variable valve operating device according to the present invention includes a valve mechanism that can select a dual valve variable control mode in which the valve opening amounts of a first valve and a second valve, which are of the same type and provided for the same cylinder, can be varied continuously or in multiple steps. A valve opening amount difference is provided when the valve opening amounts are minimized in the dual valve variable control mode so that the valve opening amount of the first valve is larger than that of the second valve. In addition, adjustments are made so that the minimum valve opening amount of the first valve does not vary from one cylinder to another.

摘要： The present invention relates to a variable valve operating apparatus having a switching mechanism for switching between a dual valve variable control mode and a single valve variable control mode, and enhances the durability of the switching mechanism.In an idle state prevailing before a vehicle starts moving, the operating state of an internal combustion engine is in a single valve small lift region (point A). In this instance, the single valve variable control mode prevails. After the vehicle starts moving, the operating state changes from point A through point B to point C and switches to a dual valve great lift region. Subsequently, when an accelerator pedal is released with a clutch disengaged for upshifting, the operating state reverts to point A in the single valve small lift region. In the above situation, as the operating state remains in the dual valve great lift region for a short period of time, a switch to the dual valve variable control mode does not constitute a considerable advantage. Therefore, the switch to the dual valve variable control mode is prohibited when the operating state changes from point B to point C.
摘要翻译： 本发明涉及一种具有切换机构的可变气门操作装置，用于在双阀可变控制模式和单阀可变控制模式之间切换，并提高切换机构的耐久性。 在车辆开始移动之前的空闲状态下，内燃机的运行状态为单个阀小升程区域（A点）。 在这种情况下，以单阀可变控制模式为准。 车辆开始移动后，运行状态从A点到B点变化到C点，并切换到双阀门大升程区域。 随后，当用离合器分离用于升档的情况下释放加速器踏板时，在单个阀小提升区域中的操作状态恢复到点A. 在上述情况下，随着操作状态在短时间内保持在双阀大升程区域中，切换到双阀可变控制模式不构成相当大的优点。 因此，当运行状态从点B变为点C时，禁止切换到双阀可变控制模式。

摘要： A sequential turbocharger system for an internal combustion engine with an exhaust gas recirculation system. The sequential system includes a large-volume turbocharger and a small-volume turbocharger, which are arranged in series in the direction of the flow of gases. A bypass passageway is connected to an exhaust pipe to thereby bypass the turbine of the small-volume turbocharger, and an exhaust switching valve is arranged in the bypass passageway for controlling the flow of exhaust gas to the turbine of the small-volume turbocharger. The EGR system includes an exhaust gas recirculation passageway for introducing an amount of exhaust gas into the intake pipe of the engine. The exhaust gas for recirculation is taken out from the intake pipe at a position located between the turbines of the small-volume and large-volume turbochargers.
