Abstract

A controller increases an actual oil pressure up to a transient oil pressure (an actuating oil pressure) and then supplies oil adjusted to have the transient oil pressure (the actuating oil pressure) to valve stopping mechanisms to actuate the valve stopping mechanisms. The controller, when actuating the valve stopping mechanisms, starts increase in an intake filling amount when the actual oil pressure increases up to a predetermined determination value set at the transient oil pressure (the actuating oil pressure) or lower.
