ABSTRACT:
A valve operating system of an engine opens and closes a valve by a swing cam being swung by rotation of an operating cam. The operating cam has a cam surface and is rotated by the engine, and the swing cam has a cam surface in sliding contact with the valve and a cam follower in sliding contact with the cam surface of the operating cam. The cam surface of the operating cam and the cam surface of the swing cam are formed so that an acceleration component of the swing cam is larger than that of the operating cam in a positive region of a valve lift acceleration defined as a sum of the acceleration component of the operating cam and the acceleration component of the swing cam.
