Claim Text:
1. A flow rate controller of an internal combustion engine, the flow rate including a flow rate of exhaust gas that is recirculated to an intake system from an exhaust system of the internal combustion engine via an EGR passage and a flow rate of fresh air that flows into the internal combustion engine, the flow rate controller comprising: a flow rate change section configured to change at least one of the flow rate of the exhaust gas and the flow rate of the fresh air; and an electronic control unit configured to: (a) determine an arrival position of condensed water in the EGR passage at least either at the time of acceleration or at the time of deceleration of the internal combustion engine, the condensed water being moved in the EGR passage by EGR, and (b) control the flow rate change section on the basis of the arrival position.
