Abstract: Methods and systems are provided for exhaust heat recovery and EGR cooling via a single heat exchanger. In one example, a method may include selecting a specific mode of operation of an engine exhaust system with the heat exchanger based on engine operating conditions and an estimated fuel efficacy factor. The fuel efficiency factor may take into account fuel efficacy benefits from EGR and exhaust heat recovery.

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: A system for optimizing power consumption of a vehicle includes a cooling fan, an active grille shutter (AGS) system, and a plurality of heat exchangers. At least one controller is provided including a processor including computer-executable instructions for selecting a pairing of a cooling fan speed and AGS system position to provide a required airflow to a dominant one of the plurality of heat exchangers, or to an entire vehicle component system, at a minimum total combined cooling fan and AGS system power consumption. Methods for optimizing vehicle power consumption are described utilizing the system.
