Abstract: 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.

Abstract: 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.

Abstract: An intake system for an internal combustion engine includes a suction duct with a lateral bulge, an exhaust gas recirculation duct with a port into the suction duct, and a crankcase breather duct which extends into the lateral bulge in the suction duct.

Abstract: A regulating device for an internal combustion engine includes a housing in which is formed an exhaust gas recirculation pipe which opens into an intake pipe, and a regulating element eccentrically mounted on a shaft. The regulating element includes a first surface, a second surface, and guide ribs arranged on the second surface so that an exhaust gas flow flows into the intake pipe when the exhaust gas recirculation pipe is opened. In a first end position of the regulating element, where the intake pipe is at 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, where the exhaust gas recirculation pipe is closed, a normal vector of the second surface points to the exhaust gas recirculation pipe.

Abstract: Methods and systems are provided for an EGR cooler comprising a phase-change material. In one example, exhaust gas may be conducted through the EGR cooler when an engine is deactivated to maintain an engine temperature.

Abstract: An engine system is provided that includes a compressor including an inlet upstream of an impeller and a compressor housing, a flow-guiding device including a first partition extending across a valve housing, where the valve housing defines a boundary of an airflow duct, and a valve unit including an exhaust gas recirculation (EGR) valve coupled to a junction point between an EGR conduit and a compressor inlet and including and a flap having a recess mating with the first partition and pivoting about a mounting interface adjacent to a leading edge of the flap, a valve housing coupled to the compressor housing, where during actuation of the EGR valve a relative position between the recess in the flap and the first partition is varied.

Abstract: 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.

Abstract: Methods and systems are provided for de-icing a charge-air cooler of a boosted engine system when the engine is turned off. In one example, a method may include recirculating air through a bypass passage including an activated electric supercharger and the CAC. The air is warmed by compression and thaws ice accumulated in the CAC.

Abstract: Methods and systems are provided for reducing pumping losses during a partial deactivation. In one example, a method may include applying negative pressure to a deactivated cylinder group to remove gases trapped therein while an activated cylinder group continues to combust.
