Abstract: <P>PROBLEM TO BE SOLVED: To more reliably suppress the variation in the oxygen concentration of intake air before and after fuel addition in an internal combustion engine equipped with a high pressure EGR device and low pressure EGR device.  <P>SOLUTION: When fuel is added to exhaust air on the upstream side from a connection part of a low pressure EGR passage, a change occurring in an air-fuel ratio of the low-pressure EGR gas with the fuel addition is predicted. On the basis of the predicted value, a low pressure EGR gas amount is controlled so that an oxygen concentration of intake air when the low pressure EGR gas having the changed air-fuel ratio flows into an intake passage becomes leaner than target oxygen concentration. After a measurement value of the air-fuel ratio of the low pressure EGR gas changed with the fuel addition is obtained by an air-fuel ratio sensor, a high pressure EGR gas amount is controlled on the basis of the measurement value so that the oxygen concentration of the intake air when intake air controlled to be leaner than the target oxygen concentration is merged with high pressure EGR gas agrees with the target oxygen concentration.  <P>COPYRIGHT: (C)2011,JPO&INPIT
