Abstract

A controller for an internal-combustion enginehas an intake camL for a low load operation and an intake camH for a high load operation. The controller switches the intake cam used to actually open/close an intake valveand changes the phase angle of each intake cam according to the load on an internal-combustion engine while the internal-combustion engineis in operation. At a startup of the internal-combustion engine, the controller holds the intake camH for a high load operation as the intake cam that actually opens/closes the intake valve, and changes the phase angle of the intake camH according to the temperature of the internal-combustion engineand/or the temperature of the atmosphere.
