Abstract
An engine includes a turbocharger, an air bypass valve, a wastegate valve, and an EGR apparatus. The engine also includes an ISC passage that connects an upstream side and a downstream side of a throttle valve in an intake passage, and an ISC valve that adjusts an amount of air flowing through the ISC passage. A control apparatus for the engine performs valve opening control to set an opening of an ISC valve at a larger opening than a reference opening when a required torque required by the engine is smaller than an estimated torque that can be generated by the engine, and closes the air bypass valve and the wastegate valve for a fixed period following completion of the valve opening control when an EGR valve of a low pressure EGR apparatus is opened during execution of the valve opening control.
