摘要： 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.

摘要： This disclosure relates to a system and method for heating an electrified vehicle. An exemplary electrified vehicle includes a passenger cabin, and an infrared heater configured to radiate heat for conditioning the passenger cabin. The vehicle further includes a heating device configured to heat airflow for conditioning the passenger cabin. Further, the vehicle includes a controller configured to selectively command a change in an output of the heating device based on an amount of power available to the infrared heater.

摘要： 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.

摘要： An engine cooling system includes a liquid-to-air heat exchanger having an associated fan and a pump forcing convection and a controller communicating with the fan and the pump, the controller increasing fan speed in response to a first gradient in heat transfer rate to power exceeding a second gradient in heat transfer rate to power for increasing pump speed, and increasing pump speed when the second gradient is greater than the first gradient. The controller may increase the pump speed in response to a desired increase in heat transfer rate. The first gradient may be based on a gradient in heat transfer rate to air flow from a map of heat exchanger performance. The second gradient may be based on a gradient in heat transfer rate to coolant from a map of heat exchanger performance.

摘要： An exhaust gas heat recovery system for a vehicle is configured to selectively distribute a fluid heated by engine exhaust to a first path for generating electricity and a second path for heating one or more powertrain components of the vehicle. A controller selects a distribution of the fluid to the first and second paths based on minimizing a fuel consumption of an engine. The controller further selects a distribution of fluid to the powertrain components to minimize fuel consumption. The controller distributes the fluid according to the selected distribution.
