摘要： An engine includes a cylinder liner. The cylinder liner includes an interior wall, an exterior wall, and a thermoelectric element disposed therebetween. The interior wall forms a cylinder bore forming part of a combustion chamber. The exterior wall is positioned adjacent a coolant jacket. The thermoelectric element is operable to generate an electric current in response to a temperature gradient between the interior wall, which is exposed to the high temperatures of the combustion chamber, and the exterior wall, which is exposed to the cooler temperatures of a coolant in the coolant jacket. An electric current in a circuit of the thermoelectric element may be controlled to affect a cylinder wall temperature. The circuit of the thermoelectric element may be opened, and the voltage of the thermoelectric element may be measured and used to calculate the cylinder wall temperature.

摘要： An apparatus for mitigating fouling within a heat exchanger device includes an internal combustion engine and an external exhaust gas recirculation (EGR) circuit. The internal combustion engine is fluidly coupled to an intake gas manifold upstream of the engine and an exhaust gas manifold downstream of the engine. The EGR circuit is fluidly coupled to the exhaust gas manifold at a first end and is configured to selectively route back exhaust gas flow as EGR flow into the intake gas manifold at a second end. The EGR circuit includes the heat exchanger device for cooling the EGR flow prior to entering the intake manifold and a surface deposit removing device configured to remove surface deposit build-up from within the heat exchanger device when the surface deposit removing device is activated.

摘要： A monitoring assembly for an electrochemical cell of a secondary lithium battery includes a porous sensory structure and a transducer. The porous sensory structure includes a sensory layer disposed on a major surface of a porous separator and a buffer layer disposed between the sensory layer and a facing surface of a negative electrode layer. The buffer layer electrically isolates the sensory layer from the facing surface of the negative electrode layer. The sensory layer includes an electrically conductive material and is configured to produce a response to an input signal or to a physical stimulus received within the electrochemical cell. The transducer is configured to process the response produced by the sensory layer to generate an output signal indicative of a diagnostic condition within the electrochemical cell.

摘要： A battery cell thermal conditioning system for a vehicle includes a battery pack having multiple battery cells. Multiple foam layers are individually positioned between first successive ones of the battery cells. A first carbon nanotube sheet is positioned in direct contact with one of the battery cells on a first side of the foam layers and a second carbon nanotube sheet is positioned in direct contact with a different one of the battery cells on a second side of the foam layers. A cooling plate is positioned between second successive ones of the battery cells. A controller directs current flow to the first carbon nanotube sheet and the second carbon nanotube sheet when a temperature of the one of the battery cells contacted by the carbon nanotube sheet drops below a predetermined threshold temperature.
