Abstract: 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.

Abstract: A vehicle airbag and restraint system includes a vehicle seat positioned in a vehicle. At least one pressure sensor is included with the vehicle seat to sense when a user is in contact with the vehicle seat. At least one airbag is opened in response to a vehicle crash event. A controller determines when the user is seated on the vehicle seat in a position different than a normally upright position thereby defining the user being out-of-position, and generates a signal applied by the controller to modify an opening sequence of the at least one airbag when the user is out-of-position.

Abstract: A climate control system includes a memory, a compensation module, and a climate control module. The memory is configured to store images captured by one or more image sensors. The compensation module is configured to: based on the images, estimate a clothing level of a first occupant in an interior cabin of a vehicle or receive the clothing level from at least one of an edge computing device or a cloud-based network device; determine a first EHT setpoint; and determine a first resultant EHT based on the clothing level and the first EHT setpoint. The climate control module is configured to: determine a first EHT error based on the first resultant EHT and a cabin temperature setpoint; determine a control value based on the first EHT error; and set climate control parameters to control a temperature of a first zone within the interior cabin based on the control value.

Abstract: 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.

Abstract: 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.
