摘要： The EGR device comprises an EGR control valve installed in an EGR passageway communicating with an exhaust system and an intake system of an internal combustion engine. An oxygen sensor detects the oxygen content of the intake air installed in the downstream of the opening of the EGR passageway in the intake system. A pressure sensor detects the atmospheric pressure in the oxygen sensor. An EGR controller computes a first quantity corresponding to a target exhaust gas reflux rate, correcting the output signal of the oxygen sensor using the output signal of the pressure sensor. The EGR control valve is opened or shut in proportion to the deviation of the second quantity thus corrected from the first quantity in order to set the operating condition of the engine in conformity with a predetermined target EGR rate.
