Abstract
The invention provides an internal combustion engine equipped with a variable valve control system which switches the actions of an engine valve by sliding a rocker arm in the axial direction of the rocker arm shaft, while enabling the restriction on the sliding movement of the rocker arm to be removed in accordance with the timings of the actions of the rocker arms irrespective of the engine speed. The internal combustion engine includes an actuator that moves a rocker arm shaft in its axial direction, a trigger arm that engages with a rocker arm to prohibit the sliding movement of the rocker arm, and a trigger pin which is configured to be activated by an axial movement of the rocker arm shaft to bring the trigger arm into action, and to disengage the trigger arm from the rocker arm.
