Abstract:
In a variably operated valve system for a multi-cylinder internal combustion engine and a control apparatus for the variably operated valve system, a first valve stop mechanism is configured to switch between a valve operation state in which one of a pair of intake valves from among the pair of intake valves of a part of a plurality of cylinders is operated to be open or closed and a valve stopped state in which the valve open or closure operation of the one of the intake valves is stopped, a second valve stop mechanism is configured to switch between the valve operation state in which the other of the pair of intake valves from among the pair of intake valves of the part of the cylinders is operated to be open or closed and the valve stopped state in which the valve open or closure operation is stopped.
