VARIABLE VALVE ACTUATION APPARATUS FOR INTERNAL COMBUSTION ENGINE

摘要

In a variable valve actuation apparatus for an internal combustion engine, a rotor of a variable valve timing mechanism is fixed to one end of a camshaft by a plurality of bolts. An oil control valve configured to control hydraulic pressure that acts on the rotor is fixed to the rotor by one or some of the plurality of bolts. For this reason, by releasing fastening of the bolt that fixes the oil control valve to the rotor among the plurality of bolts that fix the rotor to the one end of the camshaft, the oil control valve is allowed to be removed from the rotor while the rotor is fixed to the camshaft. Therefore, it is not required to perform positioning for fixing the rotor to the camshaft at the time of replacement of the oil control valve.
