Abstract
An internal combustion engine system is provided with a cam switching device including a cam groove provided on the outer peripheral surface or a camshaft and an actuator capable of protruding, toward the camshaft, an engagement pin that is engageable with the cam groove. The internal combustion engine system is configured, in causing the cam switching device to perform a cam switching operation, to control the actuator such that the engagement pin is seated on a forward outer peripheral surface which is located more forward than an end of the cam groove on the forward side with respect to an insert section of the cam groove in the rotational direction of the camshaft.
