    • A variable valve operating system of an internal combustion engine comprises a first variable mechanism 1 capable of variably controlling a lift characteristic of an intake valve 12, and a second variable mechanism 2 capable of variably controlling a valve-open and/or valve-close timing characteristic of the intake valve. The first variable mechanism varies an oscillating position of an oscillating cam 17 via a transmission mechanism 18 by controlling a rotational position of a control shaft 32 by an electric motor 34. On the other hand, the second variable mechanism is constructed to change a phase by axially moving a ring gear 43 by way of hydraulic-pressure supply or release to and from first and second hydraulic pressure chambers 49 and 50 so as to produce relative rotation between a timing sprocket 40 and a drive shaft 13. At the initial state of engine starting, the system operates to drive only the first variable mechanism. Therefore, by using an energy source for the first variable mechanism separated from an energy source for the second variable mechanism, in presence of a failure in one variable mechanism, it is possible to prevent the engine performance from lowering, and also to enhance the engine startability.
    • 内燃机的可变气门操作系统包括能够可变地控制进气门12的升程特性的第一可变机构1和能够可变地控制阀打开和/或闭阀定时的第二可变机构2 进气门特性。 第一可变机构通过由电动机34控制控制轴32的旋转位置,通过变速机构18来改变摆动凸轮17的摆动位置。另一方面,第二可变机构构造成通过 通过对第一和第二液压室49和50的液压供应或释放来轴向移动环形齿轮43,以便在正时链轮40和驱动轴13之间产生相对旋转。在发动机的初始状态 启动时,系统只能驱动第一个可变机制。 因此,通过使用与用于第二可变机构的能量源分离的第一可变机构的能量源,在存在一个可变机构的故障的情况下,可以防止发动机性能下降,并且还可以增强发动机 可启动性。
