A control device for an internal combustion engine includes an intake channel, an exhaust gas recirculation channel which enters into the intake channel, a control element, a mixing housing which forms the intake channel, a connection element, a compressor, and a shaft. The mixing housing has a mouth of the exhaust gas recirculation channel in a lower area, an outlet, a mixing housing section, and a bowl-shaped recess. The cross-sectional extension is formed via the mixing housing to provide an axial stop face. The connection element abuts against the axial stop face and is radially limited by an axially opposite inner wall surface on the stop face. The mixing housing section has a recess arranged at the lowest point of the mixing housing section and below the axially opposite inner wall surface. The recess enters into the bowl-shaped recess of the mixing housing.

A control device for an internal combustion engine includes an intake channel with an inlet and an outlet, a control element, an exhaust gas recirculation channel with an opening, a recirculation channel, and a shaft having the control element eccentrically mounted thereon. The exhaust gas recirculation channel enters the intake channel. The opening of the exhaust gas recirculation channel is a valve seat for the control element. The shaft acts as an axis of rotation for the control element. A rotation of the shaft moves the control element between a first end position where the control element throttles the intake channel and a second end position where the control element contacts the valve seat at the opening of the exhaust gas recirculation channel. The axis of rotation is arranged in a plane which passes through the valve seat at the opening of the exhaust gas recirculation channel.

A regulating device for an internal combustion engine includes an exhaust gas recirculation pipe which opens into an intake pipe which are both formed in a housing, and a regulating element eccentrically mounted on a shaft. The shaft is arranged perpendicular to a center line of the intake pipe and the exhaust gas recirculation pipe. The regulating element includes a first surface, a second surface, and guide ribs arranged on the first surface. In a first end position of the regulating element, in which the intake pipe is at least throttled upstream of an opening of the exhaust gas recirculation pipe, a normal vector of the first surface points to an upstream side of the intake pipe. In a second end position of the regulating element, in which the exhaust gas recirculation pipe is closed, a normal vector of the second surface points to the exhaust gas recirculation pipe.

A low-pressure loop EGR device for an engine with a supercharger, EGR passage, and EGR valve. An ECU controls the EGR valve to fully close, the intake valve to fully open, and the throttle valve to open at a sonic opening degree during deceleration and fuel cut-off. The ECU obtains an actual opening degree of the throttle valve based on the detected intake amount and a predetermined reference formula of valve passing flow rate. The ECU performs correction control of the throttle valve based on a throttle opening degree correction value learned from a difference of the actual opening degree and the predetermined opening degree. The ECU obtains an actual opening degree of the intake valve similarly to the above, and performs correction control of the intake valve based on an intake opening degree correction value learned by the difference between the actual opening degree and the predetermined opening degree.
