Abstract: To disclose a technology for preventing an excessive valve-opening at valve-opening, in an EGR device having an inner valve-opening type EGR valve.SOLUTION: An ECU 80 of an EGR device 21 having an inner valve-opening type EGR valve 31 determines the presence or absence of foreign matters which are bitten between a valve seat 34 and a valve body 35, and determines a foreign matter opening being an opening of the EGR valve 31 corresponding to a bite-in amount of the foreign matters. Also, in the case where there arises a valve-opening requirement of the EGR valve 31, when the presence of the foreign matters is not determined, the ECU 80 performs valve-opening control for making the opening of the EGR valve 31 approximate to a target opening of the EGR valve. On the other hand, in the case where the presence of the foreign matters is determined, when the target opening of the EGR valve 31 is smaller than the foreign matter opening, the ECU prohibits the valve-opening control of the EGR valve 31, and when the target opening of the EGR valve 31 reaches the foreign matter opening or smaller, starts the valve-opening control with the foreign matter opening as an actual control opening of the EGR valve.SELECTED DRAWING: Figure 9
