Abstract
Provided is a variable valve operating apparatus for an internal combustion engine, which can favorably reduce electric power consumption in a vehicle system that may stop the internal combustion engine during power-up of the vehicle system. A changeover mechanismis provided which is capable of switching between a connection state in which a first rocker armand a second rocker armare in connection with each other via a changeover pinand a disconnection state in which the connection is released. The changeover mechanismperforms energization of actuatorsfor each cylinder in a case in which fuel supply to the internal combustion engineis stopped in response to an establishment of a predetermined stop condition. The above-described energization of the actuatorfor each cylinder is stopped in a case in which a crankshaftof the internal combustion enginestops rotating during an energization time period of the actuatorand in which the crankshaftis not driven by an external power.
