Abstract
An EGR control apparatus for an internal combustion engine, which is capable of properly controlling an inert gas amount of two types of EGR gas supplied to cylinders of the engine via two paths different from each other, thereby making it possible to ensure a stable combustion state, reduced exhaust emissions, and improve operability. The EGR control apparatus includes low-pressure and high-pressure EGR devices, and an ECU. The ECU controls the low-pressure and high-pressure EGR gas amounts according to engine speed and demanded torque, and when a combination of engine speed and demanded torque is in a predetermined region, the low-pressure and high-pressure EGR gas amounts are controlled such that inert gas in low-pressure EGR gas exceeds in amount inert gas in high-pressure EGR gas, and the former more exceeds the latter as engine speed is higher or demanded torque is larger.
