Abstract: When an acceleration flag is not set, an amount of target rotation tvttbb1 of a variable valve mechanism is set on the basis of an amount of intake air and an engine speed. On the other hand, when the acceleration flag is set, an amount of target rotation of the variable valve mechanism is set on the basis of the engine speed, a cooling water temperature, and an atmospheric pressure. As described above, when the acceleration flag is not set, i.e., when the amount of intake air does not change excessively, the amount of target rotation based on the amount of intake air is used, so that the valve timing can be controlled appropriately.

Abstract: The system, according to one embodiment of the present invention, comprises a stationary coil linear motor to drive a valve with a stem comprising a ferromagnetic property. The linear motor moves the valve in response to control governed by an electronic valve control computer. The valve is movable between a closed position at a selectable rate of both acceleration and speed for a selectable distance (“lift”) to a second selectable open position, including all position variations between the fully open and fully closed states. Valve position, velocity and acceleration can be varied both during a valve stroke and from one stroke to the next, as controlled by the logic programmed on a non-transitive memory of the electronic valve control computer.

Abstract: In a hydraulic variable valve timing mechanism including a lock pin that locks a vane rotor and a housing against relative rotation in the most retarding phase, a specified angle α is set so that release of the lock pin is started at a time when positive cam torque acts on the vane rotor. When the crank angle reaches the specified angle α, supply of hydraulic pressure to the advancing oil chamber is started to release the lock pin from the engagement with the lock hole, thereby enabling a reliable release of the lock pin prior to start of change of valve timing.
