Abstract:
In an engine which comprises a first intake valve and a second intake valve for each cylinder, configured to be driven by a first intake cam and a second intake cam, respectively, and a cam phase change mechanism configured to vary the phase of the second intake cam, the cam phase change mechanism is controlled so that the opening timing of the second intake valve is advanced ahead of that of the first intake valve in a start mode.
