摘要： A valve driving apparatus for an internal combustion engine. Each combustion chamber has a pair of intake ports and a pair of intake valves for selectively opening and closing the intake ports. Each intake valve is driven with a variable amount of valve lift. The apparatus includes a camshaft rotatably supported by the engine, cams, cam followers, a shaft moving mechanism, and brackets. Each cam lifts an associated intake valve in response to rotation of the camshaft. Each cam has a cam nose for lifting a corresponding intake valve. The radius of the cam nose varies in the axial direction. Cam followers transmit movement of the intake cams to the intake valves. The shaft moving mechanism moves the cams relative to the valves in an axial direction of the camshaft thereby varying the amount of valve lift. A lifter structure is provided that is circularly shaped to improve manufacturing accuracy. In another embodiment, the valves are oriented to increase the amount of axial movement that the cam can make, which results in greater optimization of the air intake amount.

摘要： A hydraulic actuator including a piston connected to a camshaft. First and second passages extend through the camshaft. The piston is actuated in accordance with differences in pressure applied to the piston through the passages. A bearing rotatably supports the camshaft. The first and second passages open at the circumferential surface of the camshaft. First and second grooves are defined in the bearing and arranged at different positions with respect to the axial and circumferential directions of the camshaft. The first and second grooves are communicated with the first and second passages such that the grooves form substantially sealed hydraulic passages for carrying hydraulic fluid to or from the passages while the camshaft rotates.

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 are wider in a load bearing portion of the bearing. In another embodiment, the grooves do not extend into a non-load bearing portion of the bearing.

摘要： A variable valve timing apparatus includes: a variable valve timing mechanism that changes a valve timing and locks the valve timing at a most retarded timing; an oil control valve that controls a mode in which hydraulic fluid is supplied to the variable valve timing mechanism; and a controller that varies a duty ratio of the oil control valve within a set range that includes an advance active band, a retard active band, a holding range, an advance release range and a retard release range. In the advance release range, a varying speed of the valve timing is higher than the holding range and a housing rotor is disengaged from a vane rotor. When an engine operating state is a release request state, the controller sets the duty ratio of the oil control valve within the advance release range.

摘要： A control apparatus for an internal combustion engine is employed for a multi-cylinder internal combustion engine. The control apparatus includes a variable valve operating mechanism which changes a valve characteristic of an engine valve; a valve stop mechanism which stops opening/closing of the engine valve in at least one cylinder; and a controller which executes a variable valve control that makes an actual value of the valve characteristic match a target value by executing a hydraulic pressure control for the variable valve operating mechanism, and which operates the valve stop mechanism so that a reduced-cylinder operation is performed when an engine operating state is in a preset reduced-cylinder operation region. If it is determined that a pressure of hydraulic fluid supplied to the variable valve operating mechanism satisfies a preset condition when the engine operating state is in the reduced-cylinder operation region, the controller prohibits the variable valve control.

摘要： A control apparatus and a control method for a variable valve operating mechanism are employed for a multi-cylinder internal combustion engine including the variable valve operating mechanism and a valve stop mechanism. The variable valve operating mechanism includes a variable mechanism portion that changes a valve characteristic of an engine valve, and an actuator that drives the variable mechanism portion. The valve stop mechanism stops opening/closing of the engine valve in at least one cylinder. A controlled variable for the actuator is set so that an actual value of the valve characteristic matches a target value. A control characteristic value used to set the controlled variable, and used to make the actual value match the target value, is set such that when a reduced-cylinder operation is performed, the control characteristic value is different from the control characteristic value when an all-cylinder operation is performed.

The engine in the low rotation state has a rotation speed lower than a predetermined rotation speed. The engine in the high rotation state has a rotation speed equal to or higher than the predetermined rotation speed.

摘要： The engine operational region in which the cylinder deactivation operation is performed in the cylinder deactivation control is switched between the cylinder deactivation region AP1 and the cylinder deactivation region AP2 depending on whether a variable valve timing mechanism is in an operation allowed state and control of the valve timing of an intake valve is being performed, or the variable valve timing mechanism is in an operation inhibited state and the control of the valve timing of the intake valve is stopped. In this way, depending on whether the variable valve timing mechanism is in the operation allowed state or in the operation inhibited state, the engine operational region in which the cylinder deactivation operation is performed can be set so that the engine operational region is made suitable for each of these state.
