Abstract

This device for controlling the flow rate in an internal combustion engine is provided with a flow rate alteration unit that, as a flow rate alteration unit that can alter at least one of either the flow rate of exhaust gas recycled to an intake system (10) from an exhaust system (20) of the internal combustion engine (50) via an EGR pathway or the flow rate of new air flowing into the internal combustion engine (50), is configured having an EGR valve (43), a bypass valve (45), and a diesel throttle (13). Further provided i s an ECU (70) that realizes: an arrival position determination unit that determines the arrival position of condensed water within the EGR path way and moving by means of the EGR during at least one of either times of acceleration or times of deceleration of the internal combustion engine (50); and a control unit that controls the flow rate alteration unit on the basis of the arrival position determined by the arrival position determination unit.
