摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Embodiments for generating vacuum at a throttle are presented. In one example, a system comprises a throttle positioned in an intake of an engine, and a peripheral venturi proximate the throttle, the venturi having an inlet positioned to interface with an edge of the throttle when the throttle is in a partially open position. In this way, vacuum may be generated by flow air through the venturi.

摘要： 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.
