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 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 determining degradation of an EGR cooler based on differential pressure across the EGR cooler during EGR flow. In one example, the differential pressure across the EGR cooler may be based on differential pressure across an EGR valve and a pressure downstream from the EGR valve with and without EGR flow. The pressure downstream from the EGR valve may be a compressor inlet pressure or an intake manifold pressure in a low pressure EGR system or high pressure EGR system, respectively.

Abstract: Methods and systems are provided for exhaust gas heat recovery at an 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. Hot 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.

Abstract: Methods and systems are provided for reducing torque transients experienced when a dedicated EGR cylinder is transitioned in to or out of dedicated EGR mode. During a transition, each of an intake throttle and a wastegate is adjusted in opposing directions. Throttle and wastegate adjustments are coordinated with adjustments to spark timing and intake cam timing to provide sufficient torque reserve for the transition.

Abstract: Methods and systems are provided for airflow control in an engine system which includes a throttle turbine generator including a turbine and a turbine generator. In one example, a method may include adjusting an angle of a throttle positioned in an engine inlet passage based on a desired airflow by taking into account the effects on the throttle angle due to rotation motion of the turbine, thereby accurately controlling airflow to the engine system. The method may further include predicting an airflow to the engine system based on the position of the throttle, thereby accurately monitoring torque of the engine system.

Abstract: Methods and systems are provided for providing auxiliary heat to a charge air cooler to reduce condensate formation. A coolant valve may control the delivery of heated engine coolant to the inlet side of the charge air cooler. The coolant valve may be adjusted based on condensate formation in the charge air cooler and a temperature at the charge air cooler outlet.

Abstract: Methods and systems are provided for adjusting a reference voltage for an intake manifold oxygen sensor based on ingestion of hydrocarbons from a fuel system canister and/or an engine crankcase. During conditions when purge or crankcase ventilation hydrocarbons are ingested in the intake aircharge, the intake oxygen sensor is transitioned from operating at a lower reference voltage to a higher reference voltage where the effects of the ingested hydrocarbons on the sensor output are nullified. An EGR dilution of the intake aircharge is estimated based on the output of the sensor at the higher reference voltage while an amount of hydrocarbons ingested is estimated based on a difference between sensor outputs at the higher and lower reference voltages.
