摘要： An IIS system that performs control related to intermittent stopping of engine operation by idling stop control is applied to an internal combustion engine including a VVT mechanism that makes the valve timing of an engine valve variable and has an intermediate lock mechanism that mechanically locks the valve timing at an intermediate lock position between a most retarded position and a most advanced position. The IIS system is configured to inhibit the engine operation from being intermittently stopped at the occurrence of a failure of the VVT mechanism to avoid the internal combustion engine from being prevented from being restarted after the intermittent stop depending on the occurrence of the failure of the VVT mechanism.

摘要： A variable valve actuation device for an internal combustion engine includes a variable valve timing mechanism and a valve timing restricting mechanism. When the operating state of the variable valve timing mechanism is in the phase restricting state and the operating state of the variable valve timing mechanism is changed to the phase releasing state on the basis of pressing the accelerator pedal, a torque limiting control is then performed to limit an increase in the torque of the internal combustion engine. With this control the rate of increase of the torque is set less than the rate of increase of the torque corresponding to the operation of pressing the accelerator pedal by retarding and correcting the ignition timing. Thus, when the operating state of the variable valve timing mechanism is changed from the phase restricting state to the phase releasing state, thereby reducing discomfort experienced by the driver.

摘要： A variable valve gear for an internal combustion engine includes: a cam base portion integrally or separately provided in a camshaft, and immovably fixed to the camshaft; a cam lobe portion connected to the cam base portion so as to swing and shift between a first state where the cam lobe portion is positioned to project from an outer circumference of the base portion and a second state where the cam lobe portion is positioned to be lower than the cam base portion in the first state; a lock mechanism locking the cam lobe portion in the first and second state; and a biasing member biasing the cam lobe portion to be shifted to the first state, to such an extent that the cam lobe portion is shifted to the second state by reaction force from a cam follower when the locking mechanism is unlocked.

摘要： A valve operating device for an internal combustion engine enabling both valve timing and valve lift characteristic to be varied depending on engine operating conditions includes intake and exhaust camshafts, an eccentric cam fixed to a first one of the intake and exhaust camshafts so that an axis of the eccentric cam is eccentric to an axis of the first camshaft. A rockable cam is supported on the first camshaft so that the rockable cam rotates or oscillates about the axis of the first camshaft. A rocker arm is oscillatingly supported on an outer periphery of the eccentric cam so that a center of an oscillating motion of the rocker arm revolves around the axis of the first camshaft. Also provided is a control shaft variably controlling the center of the oscillating motion of the rocker arm.

摘要： A swing cam to actuate engine valves is rotatably disposed about a drive shaft. A first eccentric cam is tightly disposed on the drive shaft. A ring-link is rotatably disposed on the first eccentric cam. A second eccentric cam is tightly disposed on a control shaft which rotates to a given angular position in accordance with an operation condition of an associated internal combustion engine. A rocker arm is rotatably disposed on the second eccentric cam. A rod-link extends between the rocker arm and the swing cam. A first connecting pin pivotally connects a first arm portion of the rocker arm with the ring-link. A second connecting pin pivotally connects a second arm portion of the rocker arm with an end of the rod-link. A third connecting pin pivotally connects the other end of the rod-link with the swing cam. The first connecting pin is fixed to either one of the first arm portion of the rocker arm and the ring-link.
