ABSTRACT:
In an engine exhaust recirculation device, a target exhaust recirculation rate is determined based on an engine running state. The required flowpath cross-sectional area of the exhaust recirculation passage to obtain a target exhaust recirculation rate is calculated from the target exhaust recirculation rate, fresh air amount, an intake pressure and an exhaust pressure. By determining a target opening of the exhaust recirculation valve from the required flowpath cross-sectional area of the exhaust recirculation passage and a predetermined coefficient specifying a relation between the required flowpath cross-sectional area and the opening area of the exhaust recirculation valve, the precision of controlling the exhaust recirculation amount is enhanced.
