CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE HAVING SUPERCHARGER

摘要

A control apparatus applied to an internal combustion engine (1) including a turbocharger (6) in which a movable vane mechanism (17) capable of varying throttled quantity of a passage of intake air discharged from a compressor wheel (12) by varying a position of vanes (18, 54) is disposed to a compressor (6a), a low-pressure EGR passage (7) to connect an exhaust passage (4) and a section of the intake passage (3) at the upstream side from the compressor (6a), and a low-pressure EGR valve (8) to open and close the EGR passage (7), wherein it is determined whether or not the vanes (18) are locked and the low-pressure EGR valve (8) is controlled toward an opened side so as to increase exhaust gas quantity to be recirculated to the intake passage (3) via the low-pressure EGR passage (7) while switching an operating state of the internal combustion engine (1) to an emergency operating state in which output power of the internal combustion engine (1) is restricted when the vanes (18) are determined as being locked.
