Methods and systems are provided for reducing ice formation in a charge air cooler. In one example, a method includes, operating a radiator fan of a vehicle in a first direction to cool an engine of the vehicle, and reversing a direction of rotation of the radiator fan to blow heated air towards a charge air cooler, the charge air cooler arranged proximate a radiator of the vehicle. Operating the radiator fan in a first direction may be based on the engagement of one or more gears of a transmission of the vehicle while operating the radiator fan in the reverse direction may be based on an engine temperature condition, one or more ambient weather conditions, and an engine idle condition.

An engine system includes a charge-air cooler, a separator for separating water from an airflow, and an engine. The separator causes an airflow from the charge-air cooler to strike one or more partitions and change directions via a serpentine path such that water is separated out of the airflow before the airflow reaches the engine.

Methods and systems are provided for maintaining a temperature of exhaust gases of an engine within a temperature range at which catalytic conversion is most efficient. In one example, a method for controlling a temperature of exhaust gases entering a Selective Catalytic Reduction (SCR) system for an engine comprises delivering pressurized air into the exhaust gases upstream of the SCR system, the pressurized air cooled by an air cooler; and adjusting a degree of pressurization by adjusting operation of a turbocharger pressurizing the pressurized air. In one embodiment, the air cooler may be a charge air cooler of a primary turbocharger of the engine, which may flow pressurized air both to the engine and to the SCR system. In other embodiments, the air may be pressurized by an air pump or a secondary dilution turbocharger, and cooled by a secondary charge air cooler.

System for thermal management of engine exhaust

A system and method for discharging condensation from an engine system is disclosed. The system includes a drainage pathway from an upstream body that collects water to a downstream portion of the air intake system. A controller may initiate a draining event upon determining a threshold amount of water has been collected in the upstream body.

Methods and systems are provided for reducing hot fuel vapor formation in a port injection fuel rail. In one example, a method may include operating a dual fuel injection system with at least a calibrated minimum amount of port fuel injection over a wide range of engine operating conditions, even as conditions change. A direct fuel injection amount is adjusted in accordance.

Methods and systems for port fuel injection control

Methods and systems are provided for increasing engine power while reducing vehicle emissions and engine system degradation. In one example, a method may include, responsive to an engine load reaching a threshold load, increasing engine torque by increasing an amount of boost without providing exhaust gas recirculation (EGR), and, responsive to the engine torque reaching a first threshold torque, increasing the engine torque by increasing an EGR rate over a plurality of engine cycles while further increasing the amount of boost. In this way, cooling effects from the EGR enable engine air flow, and thus engine power, to be increased while engine vibrations and heat-related exhaust component degradation are decreased.

Systems and methods for increasing engine power output under globally stoichiometric operation

Methods and systems are provided for increasing engine power via partial engine enrichment and exhaust gas recirculation. In one example, a method may include enriching a first set of engine cylinders, enleaning a second set of the engine cylinders, and operating a third set of the engine cylinders at stoichiometry, exhaust gas from all of the engine cylinders producing a stoichiometric mixture at a downstream emission control device, and providing exhaust gas recirculation (EGR) to an intake passage of the engine from the first set of cylinders. In this way, cooling effects from the partial enrichment and the EGR enable engine air flow, and thus engine power, to be increased while an efficiency of the emission control device is maintained, thereby decreasing vehicle emissions.

Methods and systems for simultaneously operating port fuel injectors and direct fuel injectors of an internal combustion engine are described. In one example, port fuel injection timing is adjusted to reduce particulate matter formation in the engine so that particulate filter loading may be reduced until a time when the particulate filter may be purged.

Methods and systems for simultaneously operating port fuel injectors and direct fuel injectors of an internal combustion engine are described. In one example, operation of a port fuel injector is deactivated in response to an indication of reduced performance of a direct fuel injector so that degradation of the direct fuel injector may be reduced.

Methods and system mitigating direct injection degradation

Methods and systems for simultaneously operating port fuel injectors and direct fuel injectors of an internal combustion engine are described. In one example, operation of all of an engine's port fuel injectors may be adjusted in response to degradation of a sole port fuel injector so that an engine may operate as desired with a plurality of direct fuel injectors.

Methods and system mitigating port injection degradation

Methods and systems are provided for estimating exhaust gas recirculation (EGR) flow in an engine including an EGR system. In one example, a method may include operating the EGR system in an open loop feed forward mode based on an intake carbon di oxide sensor output above a threshold engine load and/or when a manifold absolute pressure (MAP) is above a threshold pressure, and operating the EGR system in a closed loop feedback mode based on a differential pressure sensor output when the engine load decreases below the threshold load and/or when the MAP decreases below the threshold pressure.

Methods and systems for open loop and closed loop control of an exhaust gas recirculation system

Methods and systems are provided for mitigating excessive exhaust pressures in an engine. In one example, a method may include adjusting an intake throttle responsive to exhaust pressure upstream of an exhaust turbine being higher than a threshold without reducing boost level. In this way, boost pressures may be maintained while reducing exhaust pressures.

Methods and systems for boost control based on exhaust pressure greater than a threshold

Methods and systems are provided for increasing airflow through a charge air cooler (CAC) in order to purge condensate from the CAC. In one example, a method includes increasing airflow through the CAC while maintaining torque by selectively deactivating one or more engine cylinders and increasing boost. The number of deactivated cylinders may be based on an amount of condensate within the CAC.
