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 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 exhaust flow in an engine system including a split-exhaust manifold for expediting exhaust catalyst light-off and engine warm-up while reducing condensation in the engine system. In one example, a method may include, before exhaust catalyst light-off, flowing all or more exhaust gases, via a first exhaust valve and a first exhaust manifold, to an exhaust catalyst by passing a heat exchanger. Further, after light-off but before engine coolant warms up to a threshold temperature, all or more exhaust may be delivered to the heat exchanger, via a second exhaust valve and a second different manifold, prior to flowing to the exhaust catalyst; and exhaust gas recirculation may not be provided until the coolant reaches the threshold temperature to reduce condensation.

Abstract: Methods and systems are provided for reducing torque transients experienced when a dedicated EGR cylinder is deactivated to reduce EGR. Before deactivating the dedicated cylinder, an intake throttle position and spark timing of remaining engine cylinders is adjusted to build-up torque reserve in anticipation of a negative torque transient at deactivation. Then, the throttle position or spark timing is adjusted to reduce torque when a positive torque transient is expected.

Abstract: Methods and systems are provided for accurately learning the zero point of an intake gas oxygen sensor during selected engine no-fueling conditions. The learned zero point is used to infer EGR flow and accordingly adjust EGR valve control. In addition, EGR valve leakage is diagnosed based on the zero point learned during a DFSO adaptation relative to a zero point learned during an idle adaptation.

Abstract: Methods and systems are provided for reducing corrosion of a charge air cooler and preventing engine misfire due to condensate formation. In response to an engine controller determining a condensate forming location within a charge air cooler, a grille shutter system is adjusted, moving the condensate region to a different location in the charge air cooler. Grille shutter orientation may also be controlled in response to vehicle operating conditions and condensate-forming weather conditions.

Abstract: Methods are provided for controlling a vehicle engine to improve engine efficiency utilizing onboard water condensate. In one example, condensate is collected from cooling air routed into an engine, and injected into one of a plurality of locations based on engine operating conditions to keep NOx in combustion gases below desired amounts and to avoid ignition knock in said engine. In this way, condensate build-up in the CAC is advantageously utilized, engine performance and efficiency may be improved, and harmful emissions may be reduced.

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.
