Abstract: Methods and systems are provided for cylinder deactivation to reduce tailpipe emissions and increase exhaust temperature. In one example, a method may include operating a first set of cylinders in a first combustion cycle over modified eight strokes and a second set of cylinders in a second combustion cycle over modified four strokes. Each cylinder in the first set of cylinders may be selectively deactivated via a variable displacement engine (VDE) mechanism while each cylinder in the second set of cylinders may be selectively deactivated via an active decompression technology (ADT) mechanism.

Abstract: Methods and systems are provided for a branch communication valve in a twin turbocharger system. A branch communication valve may be positioned adjacent to a dividing wall separating a first scroll and a second scroll of the twin turbocharger. In an open position, the branch communication valve increases fluid communication between the first scroll and the second scroll and in a closed position, the branch communication valve decreases fluid communication between the first scroll and the second scroll.

Abstract: Methods and systems are provided for an engine system configured with a wide range active compressor and high pressure EGR. In one example, a compressor may include an active casing treatment with a slideable sleeve may be adjusted to direct air flow through either a choke slot and surge slot to control compressor efficiency, thereby maintaining EGR flow. In another example, the compressor may comprise a variable inlet device to regulate air flow through the compressor, thereby adjusting compressor efficiency and also maintaining EGR flow.

Abstract: Methods and systems are provided for a single heat exchanger coupled to a main exhaust passage upstream of one or more exhaust catalysts or in between two exhaust catalysts for exhaust heat recovery and exhaust gas recirculation (EGR) cooling. In one example, in the pre-catalyst configuration of the heat exchanger, during exhaust heat recovery, a portion of exhaust may be routed via the heat exchanger while the remaining portion of exhaust may be routed directly to the exhaust catalysts, and fueling may be adjusted on a per-cylinder basis to maintain a target exhaust air-fuel-ratio at the exhaust catalysts.

Abstract: Methods and systems are provided for controlling LP-EGR flow in a variable displacement engine. In one example, a method may include providing a higher fixed LP-EGR percentage relative to a total intake air flow during a VDE mode, and providing a lower fixed EGR percentage relative to the total intake air flow during a non-VDE mode. Further, during a tip-out when operating in the VDE mode at a load below a threshold, transitioning out of the VDE mode after transitioning the LP-EGR from the higher fixed percentage to the lower fixed percentage.

Abstract: Methods and systems are provided for flowing a first coolant and a second coolant to a charge air cooler. In one example, a method may include flowing only a first coolant, flowing only a second coolant, or flowing a mixture of the first and the second coolants to the charge air cooler based on engine operating conditions. Further, the method may include adjusting additional engine operating parameters based on a ratio of the first coolant to second coolant flowing to the charge air cooler.

Abstract: Methods and systems are provided for reducing corrosion of a charge air cooler and reducing engine misfire due to condensate formation. In response to charge air cooler outlet temperature, electric fan operation and grille shutter opening is adjusted. Electric fan operation and grille shutter opening may also be controlled in response to vehicle operating conditions.

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 and ambient humidity. Further, 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.

Abstract: Methods and systems are provided for flowing exhaust through a second cooler, arranged downstream of a first cooler and upstream of an intake in an exhaust gas recirculation passage, and extracting condensate for water injection from condensate in cooled exhaust gas exiting the second cooler. In one example, a method may include adjusting the amount of exhaust gas flowing through the second cooler based on an amount of water stored at a water storage tank of a water injection system and engine operating conditions. Further, the method may include selectively flowing exhaust gas from the second cooler to a location upstream or downstream of a compressor in response to engine operating conditions.

Abstract: Methods and systems are provided for exhaust gas heat recovery at a split exhaust gas heat exchanger. Exhaust gas may flow in both directions through an exhaust bypass passage and the heat exchanger coupled to the bypass passage. Warm or cold EGR may be delivered from the exhaust passage to the engine intake manifold and heat from the exhaust gas may be recovered at the heat exchanger.
