摘要： An internal combustion engine is provided with a valve lift varying mechanism for intake valves and a valve phase varying mechanism for exhaust valves. A controller performs a control operation in response to a request to pause at least one cylinder while the engine is in operation. The control operation includes: a first operation of setting an intake valve lift to a zero-lift setpoint by the valve lift varying mechanism; and a second operation of setting an exhaust valve phase by the valve phase varying mechanism so as to set an exhaust valve opening timing to a first timing setpoint on an advance side of bottom dead center and set an exhaust valve closing timing to a second timing setpoint on a retard side of bottom dead center. The first and second timing setpoints are closer to top dead center than to bottom dead center.

摘要： A variable valve actuation apparatus incorporates a mechanism, mounted to a control shaft, to convert rotational motion of a camshaft into pivotal motion of a valve operating cam. The mechanism has different states corresponding to varying angular positions which the control shaft is adjustable to, respectively, The mechanism is continuously variable in state to one of the different states in response to a shift of the control shaft to one of the varying angular positions. The mechanism is also operative to vary the valve operating cam, in position, relative to the associated cylinder valve in response to a shift between the different states.

摘要： An electromagnetically operating actuator includes a casing (29) that accommodates an armature (30), a valve-closing electromagnet (32), a valve-opening electromagnet (32), and a valve-opening spring (33). The casing is fixed to an upper face of a cylinder head (21) in which an intake valve (23) and a valve litter (27) are slidably moveable. A valve-closing spring (28) is installed between the valve lifter and a bottom face of a retention hole (21a). Further, a transmission cam (46) with first and second cam surfaces (51, 52) is interposed between the valve lifter and a tappet (39) connected with the center of the armature through a tappet shaft (38). The transmission cam is pivotable upward and downward. A hydraulic lash adjuster (47) associated with the transmission cam is disposed within the casing. This arrangement can prevent the intake and/or exhaust valves from abruptly moving at the opening and closing timings, to reduce strike and abrasion noise and to improve mountability of the actuator relative to an engine.
