Abstract: Methods and systems are provided for using compressor recirculation flow via a venturi to enhance low pressure EGR flow. The opening of a compressor recirculation valve can be adjusted based on EGR flow demand to recirculate cooled compressed air through a venturi while generating vacuum for drawing EGR. The approach allows for concurrent EGR control and surge control.

Abstract: Methods and systems are provided for exhaust catalyst temperature control by metering exhaust bypass flow from a dedicated EGR cylinder. A continuously variable bypass valve may be adjusted to vary an amount of exhaust directed to an exhaust catalyst from a dedicated EGR cylinder via a bypass passage relative to exhaust recirculated to the engine intake via an EGR passage. At lower catalyst temperatures, more exhaust is metered via the bypass passage to enable catalyst temperature to be maintained above an activation level.

Abstract: Methods and systems are provided for operating exhaust valves of an engine to create more even exhaust pulses to a turbine. More specifically, the engine may include one or more dedicated exhaust gas recirculation (EGR) cylinders routing exhaust to an engine intake and one or more non-dedicated EGR cylinder routing exhaust to the turbine. In one example, a method may include operating a first set of exhaust valves of a group of non-dedicated EGR cylinders to have no exhaust valve opening overlap and operating an exhaust valve of a dedicated EGR cylinder so that opening of the second exhaust valve overlaps with opening of exhaust valves of two cylinders of the group of non-dedicated EGR cylinders.
