摘要： In a VVA apparatus, when an actual lift amount detected by a lift-amount detecting sensor exceeds a basic lift-amount target value by a predetermined value or more, ECU corrects a lift phase through a lift-phase varying mechanism to separate from a piston TDC with respect to a basic lift-phase target value.

摘要： An internal combustion engine has an intake valve control device for controlling at least intake valves. The control device comprises a first mechanism which varies a working angle of the intake valve; a second mechanism which varies an operation phase of the intake valve; and a control unit which controls both the first and second mechanisms in accordance with an operation condition of the engine. The control unit is configured to carry out controlling variation in the open timing of the intake valve effected by the first mechanism to be larger than variation in the open timing of the intake valve effected by the second mechanism.

摘要： A valve operating system of an internal combustion engine enabling both valve working angle and phase to be varied, includes a variable working angle control mechanism being responsive to a supply pressure of working fluid to adjust a working angle of an intake valve, and a variable phase control mechanism being responsive to a supply pressure of working fluid to adjust a phase of the working angle of the intake valve. A control unit controls the supply pressure to each of the control mechanisms depending on engine operating conditions. In a cold-engine state that the temperature of working fluid is below a predetermined temperature, an intake valve open timing is retarded in comparison with a predetermined stability-limit valve open timing, by limiting a controlled variable of at least one of the control mechanisms.

摘要： A valve-operating device for an internal combustion engine equipped with two cylinder banks each having a variable valve timing and working angle mechanism comprises a drive shaft, a cylindrical hollow camshaft fitted to an outer periphery of the drive shaft to be rotatable relatively about the drive shaft, a non-uniform velocity coupling including an annular disc disposed between the drive shaft and the camshaft for transmitting motion of rotation from the drive shaft to the camshaft, permitting a phase change of the camshaft relative to the drive shaft with non-uniform rotation during eccentric motion of the annular disc, and a control housing rotatably supporting the annular disc. Also provided is a decentering mechanism supporting the control housing rockably to produce the eccentric motion of the annular disc. A locus of eccentric motion of the center of the annular disc arranged in the left bank and a locus of eccentric motion of the center of the annular disc arranged in the right bank are essentially symmetrical with respect to the line perpendicular to a line segment between and including two central axes of said drive shafts of the two cylinder banks. A direction of eccentric motion of the center of the annular disc arranged in the right bank is opposite to a direction of eccentric motion of the center of the annular disc arranged in the left bank.
