摘要： A variable valve timing mechanism of an internal combustion engine varies the rotational phase of a camshaft with respect to a drive shaft to vary the timing of a set of engine valves. The mechanism includes a first rotor for a rotation in synchronism with the drive shaft and a second rotor for a rotation in synchronism with the camshaft. The second rotor has vanes, which are located in hydraulic chambers. Unequal hydraulic forces on the vanes causes the second rotor to rotate with respect to the first rotor to change the rotational phase of the camshaft with respect to the drive shaft. Hydraulic pressure is supplied to a certain side of the vanes to apply forces to the vanes. A lock member locks the second rotor to the first rotor to fix the rotational phase of the camshaft with respect to the drive shaft. The lock member unlocks the second rotor from the first rotor only when the hydraulic pressure supplied to the vanes is such that the torque produced by the hydraulic pressure on the vanes is at least as great as an oppositely directed torque resulting from rotational fluctuation of the camshaft. This prevents the vanes from colliding against the walls of their chambers, which produces noise.

摘要翻译： 内燃机的可变气门正时机构改变凸轮轴相对于驱动轴的旋转相位，以改变一组发动机气门的正时。 该机构包括用于与驱动轴同步旋转的第一转子和用于与凸轮轴同步旋转的第二转子。 第二转子具有位于液压室内的叶片。 叶片上的不均等的液压力导致第二转子相对于第一转子旋转，以改变凸轮轴相对于驱动轴的旋转相位。 液压被供应到叶片的某一侧以向叶片施加力。 锁定构件将第二转子锁定到第一转子以将凸轮轴的旋转相位相对于驱动轴固定。 仅当提供给叶片的液压使得由叶片上的液压产生的扭矩至少等于由凸轮轴的旋转波动产生的相反方向的扭矩时，锁定构件才能从第一转子解锁第二转子 。 这样可防止叶片与其室的壁碰撞，从而产生噪音。

摘要： A Variable Valve timing mechanism is provided at the distal end of a camshaft for changing a valve timing of an engine valve. A camshaft is rotatably supported by a cylinder head and bearing cap, which form a baring. A pulley is mounted on the camshaft, and is relatively rotatably with respect to the camshaft. A belt connects the pulley to a crankshaft to transmit power from an engine to the pulley. The belt applies tension to the pulley and the camshaft in a specific direction. A ring gear is positioned between the camshaft and the pulley. First and second hydraulic pressure chambers are defined at the ends of the ring gear. A first oil passage is defined in the camshaft and is connected to the first pressure chamber. A second oil passage is defined in the camshaft, and is connected to the second pressure chamber. A pair of grooves extend along the inner circumference of the cylinder head. The grooves do not extend into a non-load bearing portion of the bearing.

摘要： A vehicle includes a battery and an alternator as a power source, and a plurality of vehicle load groups that operate commonly receiving power supply from the power source. When a plurality of requests for actuating the plurality of loads are made simultaneously, a control circuit determines a request of higher priority and a request of lower priority based on a predetermined priority for each of said requests. The control circuit operates the corresponding load as requested in response to the request of high priority, and operates the corresponding load with the operation limited to consume smaller power than requested in response to the request of low priority. More preferably, one of the plurality of loads is variable valve timing apparatus changing a timing of opening/closing an intake valve or an exhaust valve of an internal combustion engine.

摘要： As for a reference valve timing varying rate A obtained by a deviation Δφ between a target VVT phase φT and an actual VVT phase φ, when a varying rate Δθth of an accelerator opening degree resulting from the manipulation of the driver is relatively low, a VVT-ECU places a limit on the valve timing varying rate. When the varying rate Δθth of the accelerator opening degree is relatively high, it varies the valve timing with the reference valve timing varying rate A.
