ABSTRACT:
A control apparatus for an internal combustion engine provided with a fuel vapor treatment system according to the invention includes a controller that discharges fuel vapor into an intake passageway by using the intake negative pressure, and which adjusts the amount of the intake air through the cooperative control of a variable control of at least one of the lift amount of an intake valve and the working angle of the intake valve, and a control of the degree of opening of a throttle valve. In addition, the control apparatus executes the variable control so that at least one of the lift amount and the working angle of the intake valve changes in accordance with the fuel vapor concentration in the fuel vapor treatment system.
