  • Patent number: 10502148
    Abstract: An electronic control unit is configured to select a first cam as a driving cam of an intake valve in a first operation range where a target value of an EGR rate is set to a specified EGR rate, and is configured to select a second cam as the driving cam in a second operation range smaller in valve duration and lift amount than the first cam. Accordingly, in most of the operation regions, the first cam is selected, and the second cam is selected only in a high-torque and high-speed region. When the second cam is selected in the high-torque and high-speed region, the state where an actual compression ratio is high can be eliminated, and suction efficiency can be decreased. Therefore, decrease in a knocking limit can be suppressed.
