摘要：In an control apparatus of an internal combustion engine, a technique isprovided in which a proper amount of EGR gas can be supplied while making narrower arange within which exhaust pulsation propagates. In the control apparatus of an internalcombustion engine including an EGR passage (41) that connects between an intakepassage (4) and an exhaust passage (8) of the internal combustion engine (1) so as tocirculate a part of an exhaust gas from the internal combustion engine (1) as an EGR gas,and an EGR valve (42) that is arranged at a location between opposite ends of the EGRpassage (41) so as to adjust a flow rate of the EGR gas by adjusting a passage area of theEGR passage (41), provision is made for an opening and closing device (46) of a normallyopen type that opens and closes the EGR passage (41) at an upstream side of the EGRvalve (42), and a change unit (90) that changes a degree of opening of the opening andclosing device (46).
