Title: Exhaust gas heat recovery system

Abstract

A powertrain includes an engine, an exhaust system including an exhaust passageway in fluid communication with the engine, an exhaust gas heat exchanger, a transmission having a transmission cooling system, a transmission heat exchanger, a heater core, a pump, and an engine coolant circuit. The engine coolant circuit provides fluid communication between the engine, the exhaust gas heat exchanger, the transmission heat exchanger, the heater core, and the pump. The exhaust gas heat exchanger is operatively connected to the exhaust system and configured to transfer heat between the engine coolant circuit and the exhaust system. The transmission heat exchanger is operatively connected to the transmission cooling system and configured to transfer heat between the engine coolant circuit and the transmission cooling system.

Method for controlling exhaust gas heat recovery systems in vehicles

Patent Spohn, Brian L.; Claypole, George M.; Starr, Richard D

A method of operating a vehicle including an engine, a transmission, an exhaust gas heat recovery (EGHR) heat exchanger, and an oil-to-water heat exchanger providing selective heat-exchange communication between the engine and transmission. The method includes controlling a two-way valve, which is configured to be set to one of an engine position and a transmission position. The engine position allows heat-exchange communication between the EGHR heat exchanger and the engine, but does not allow heat-exchange communication between the EGHR heat exchanger and the oil-to-water heat exchanger. The transmission position allows heat-exchange communication between the EGHR heat exchanger, the oil-to-water heatmore » « less

Engine system having carbon foam exhaust gas heat exchanger

Patent Dupree, Ronald L.; Dykstra, Brandon; Callas, James J.; ...

An engine system includes an engine such as a compression ignition internal combustion engine, including a heat exchanger in an exhaust system thereof. The heat exchanger including at least one carbon foam block for cooling exhaust gas with cooling air. An exhaust system segment includes a carbon foam based heat exchanger configured to exchange heat between exhaust gas and cooling air at least in part via the carbon foam.

Exhaust bypass flow control for exhaust heat recovery

Patent Reynolds, Michael G.

An exhaust system for an engine comprises an exhaust heat recovery apparatus configured to receive exhaust gas from the engine and comprises a first flow passage in fluid communication with the exhaust gas and a second flow passage in fluid communication with the exhaust gas. A heat exchanger/energy recovery unit is disposed in the second flow passage and has a working fluid circulating therethrough for exchange of heat from the exhaust gas to the working fluid. A control valve is disposed downstream of the first and the second flow passages in a low temperature region of the exhaust heat recoverymore » « less

Waste heat recovery system including a mechanism for collection, detection and removal of non-condensable gas

Patent Ernst, Timothy C.; Zigan, James A.

The disclosure describes a non-condensable gas collection, detection, and removal system for a WHR system that helps to maintain cycle efficiency of the WHR system across the life of an engine system associated with the WHR system. A storage volume is configured to collect non-condensable gas received from the working fluid circuit, and a release valve is configured to selectively release non-condensable gas contained within the storage volume.

Thermoelectric generators incorporating phase-change materials for waste heat recovery from engine exhaust

Patent Meisner, Gregory P; Yang, Jihui

Thermoelectric devices, intended for placement in the exhaust of a hydrocarbon fuelled combustion device and particularly suited for use in the exhaust gas stream of an internal combustion engine propelling a vehicle, are described. Exhaust gas passing through the device is in thermal communication with one side of a thermoelectric module while the other side of the thermoelectric module is in thermal communication with a lower temperature environment. The heat extracted from the exhaust gasses is converted to electrical energy by the thermoelectric module. The performance of the generator is enhanced by thermally coupling the hot and cold junctions ofmore » « less
