DEVICE FOR CONTROLLING INTERNAL COMBUSTION ENGINE

To provide a control apparatus for an internal combustion engine that, in a turbocharged internal combustion engine including a waste gate valve, can favorably prevent an exhaust system part disposed downstream of a turbine from overheating, regardless of opening of the waste gate valve. The control apparatus includes a turbocharger (20) having a turbine (20b) which is operative by exhaust energy and is disposed in an exhaust passage (14). The control apparatus further includes a WGV (32) for opening or closing an exhaust bypass passage (30) that bypasses the turbine (20b). Timing to start fuel quantity increase control for preventing an exhaust system part, such as a catalyst (34), from overheating is advanced when the WGV (32) is in an open state than when the WGV (32) is in a closed state.
