<p>PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine having an auxiliary air supply passage and an auxiliary air adjusting valve, and capable of cooperatively controlling a throttle valve and the auxiliary air adjusting valve in an internal combustion engine having an EGR device for taking EGR gas from the downstream side of a turbine and supplying it from the upstream side of a compressor and an electronic control type throttle valve.SOLUTION: An engine 10 comprises: an electronic control type throttle valve 40 provided in an intake passage 11; an EGR device 31; an auxiliary air supply passage 46 bypassing the throttle valve 40 and capable of supplying auxiliary air to a combustion chamber 14; and an auxiliary air adjusting valve 48. A target auxiliary air flow rate is calculated, and an opening of the auxiliary air adjusting valve 48 is operated on the basis of the target auxiliary air flow rate. Further, a target throttle flow rate is calculated, and an opening of the throttle valve 40 is operated on the basis of the difference between the target throttle flow rate and the target auxiliary air flow rate.</p> |
