Abstract: Methods and systems are provided for varying a location and rate of EGR delivered to an engine from a dedicated EGR cylinder. The dedicated EGR cylinder is configured with a plurality of exhaust valves controlled via a cam profile switching mechanism that allows the time and duration of opening of each exhaust valve to be varied. By selectively opening one exhaust valve at a time, exhaust from the dedicated EGR cylinder can be delivered to a pre-compressor location, a post-compressor location, or to the exhaust manifold, while bypassing all engine cylinders.

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 estimating water storage in a charge air cooler (CAC). In one example, an amount of water accumulating in the CAC may be based on an output of an oxygen sensor positioned downstream of the CAC, ambient humidity, and EGR flow while EGR is flowing. Additionally, engine actuators may be adjusted to purge condensate from the CAC and/or reduce condensate formation based on the amount of water inside the CAC.
