Abstract: A thermal accumulator assembly (TAA) for a vehicle waste heat recovery system (WHRS) utilizing a two-phase coolant includes a hermetically sealed housing having a separator plate dividing an interior of the housing into a higher pressure first chamber and a lower pressure second chamber. A pressure control valve is disposed between the first and second chambers. A first inlet port is connected to the first chamber and configured to receive a first flow of coolant. A first outlet port is connected to the first chamber and configured to a second flow of liquid coolant to a heat generating component in the WHRS. A second inlet port is connected to the first chamber and configured to receive a third flow of heated coolant from the heat generating component. A second outlet port is connected to the second chamber and configured to supply a fourth flow of vapor coolant to the WHRS.

Abstract: A vehicle includes a component coated with a pollutant reduction catalyst configured to remove pollutants from a flow of air over the component, a catalyst temperature sensor coupled to the component, a general temperature sensor, a vehicle speed sensor, and an active grille shutter (AGS) system having a plurality of movable grille shutters. A controller is configured to determine an efficiency of the pollutant reduction catalyst based on signals from the catalyst temperature sensor, the general temperature sensor, the vehicle speed sensor, and the AGS system.

Abstract: A chiller system includes an intercooler configured to cool compressed charge air received from a charger, a low temperature cooling circuit fluidly coupled to the intercooler, and an air conditioner circuit circulating a refrigerant and having a primary circuit and a bypass circuit. The primary circuit includes a compressor, a condenser, and an evaporator. The bypass circuit includes a conduit that bypasses the evaporator, and a chiller shut off valve is configured to selectively prevent refrigerant from flowing through the bypass circuit. A chiller is thermally coupled to the low temperature cooling circuit and the bypass circuit. A controller is in signal communication with the chiller shut off valve. The controller is programmed to, upon receiving a signal indicating a driver has manually selected the vehicle to operate in a racing mode, open the chiller shut off valve to provide increased cooling to the intercooler and the compressed charge air.
