摘要： Disclosed is a variable valve gear comprising a camshaft phase change mechanism, which variably controls a phase of an intake cam with respect to a crankshaft, and a variable valve lift mechanism, which changes an opening timing of an intake valve more than a closing timing and basically continuously varies a lift and an open period of the intake valve. The lift and the open period are set lest the intake valve interfere with a piston of an engine, with the phase controlled to be most advanced by the camshaft phase change mechanism and the lift controlled to be maximal by the variable valve lift mechanism.

摘要： A variable valve apparatus of an internal combustion engine includes a cam shaft, a drive cam formed integrally with the cam shaft, and a rocker arm mechanism for transmitting an opening/closing force from an operating end portion thereof to an intake or an exhaust valve by receiving the opening/closing force by a drive cam opposed roller brought into contact with the drive cam. For displacing a lift time period, in which the drive cam opposed roller receives the opening/closing force, frontward/rearward in a direction of rotating the drive cam, an up section of a cam lift face of the drive cam is formed to be longer than a down section thereof such that a change region of a lift valve closing time point of the lift time period becomes larger than a change region of a lift valve opening time point thereof.
