20130186076 | METHOD TO PROTECT THE EXHAUST MANIFOLD FROM OVERHEATING USING HEAT PIPE - An exhaust system for an engine is disclosed herein. The exhaust system includes a catalytic converter, an exhaust manifold upstream from the catalytic converter, and a heat pipe in thermal contact with the exhaust manifold and atmosphere. The system further includes a phase changing material that passively absorbs heat after catalytic light-off. | 07-25-2013 |
20130199164 | HEAT SYSTEM FOR AN ENGINE - An exhaust system for an engine is disclosed herein. The exhaust system includes a catalytic converter, a heat collector downstream from the catalytic converter, and a heat transfer system receiving waste exhaust heat via a thermosyphon evaporator for storage and/or use in a cabin heating system. In this way, waste heat is utilized to provide better cabin heating, particularly at engine cold start. | 08-08-2013 |
20130199750 | HEAT STORAGE SYSTEM FOR AN ENGINE - A method for recovering exhaust heat for an engine is disclosed herein. The method includes reducing a volume of a circulating heat transfer fluid and discharging a heat storage device to heat an engine component. The method further includes distributing the circulating heat transfer fluid to one or more engine systems. | 08-08-2013 |
20130199751 | HEAT STORAGE DEVICE FOR AN ENGINE - A heat recovery system for an engine is disclosed herein utilizing a heat storage unit configured to store waste exhaust heat for subsequent use on engine starts in various systems. In this way, improved system operation can be obtained by re-using such waste heat. | 08-08-2013 |
20130239923 | HEAT PIPE ASSEMBLY IN AN ENGINE LUBRICATION SYSTEM - An engine lubrication system is provided. The engine lubrication system includes an oil pan housing a lubricant, an oil pump having a pick-up tube including an inlet submerged in the lubricant, and a heat pipe assembly including a fluidly sealed heat pipe coupled to the oil pan adjacent to the inlet of the pick-up tube. | 09-19-2013 |
20130263574 | METHOD OF COLLECTION AND REUSE OF EXHAUST HEAT IN A DIESEL-POWERED VEHICLE - A heat transfer method for an engine is disclosed herein utilizing a heat battery configured to store waste exhaust heat in phase-chase materials for use during a subsequent engine start. By reusing waste exhaust heat in this manner, exhaust emissions may be reduced, and delays in heating the vehicle cabin and other vehicle systems after engine start may be reduced. | 10-10-2013 |
20140026869 | FUEL DELIVERY SYSTEM INCLUDING A HEAT PIPE ASSEMBLY - A fuel delivery system is provided herein. The fuel delivery system may include a fuel tank storing a liquid fuel, a return fuel line including an outlet opening into the fuel tank, and a heat pipe assembly including a first end positioned in a surrounding atmosphere, and a second end positioned at and coupled to the return fuel line. | 01-30-2014 |
20140047853 | MOTOR VEHICLE CLIMATE CONTROL SYSTEM - A vehicle climate control system includes a thermal-adsorption heat pump driven by engine exhaust heat, the heat pump including two adsorbers asynchronously switching between adsorbing and desorbing modes, each adsorber coupled with a corresponding antifreeze tank via a plurality of refrigerant-containing wick chambers. Cold heat transfer fluid (HTF) flows through the adsorber during the adsorbing mode which causes evaporation of refrigerant from the wick chambers, thereby cooling antifreeze, whereas hot HTF flows through the adsorber during the desorbing mode which causes condensation of refrigerant at the wick chambers, thereby heating antifreeze. In this way, the thermal-adsorption heat pump may condition cabin air independent of engine coolant and without exerting a load on the engine. | 02-20-2014 |
20140053579 | MOTOR VEHICLE CLIMATE CONTROL SYSTEM - A vehicle climate control system operable in a winter mode and a summer mode includes an engine-exhaust-driven hot heat transfer fluid (HTF) circuit coupled with a heater core during the winter mode to provide passenger cabin heating, and thermal energy stored in a standalone hot phase change material (PCM) battery in the hot HTF circuit may provide surge heating at or prior to engine start. The hot HTF circuit and a cold HTF circuit including an HTF cooler drive two adsorbers in the summer mode, thereby providing passenger cabin cooling in conjunction with a refrigerant circuit which includes a condenser, evaporator, expansion valve, and standalone cold PCM battery. Thermal energy stored in the standalone cold PCM battery may provide surge cooling at or prior to engine start. | 02-27-2014 |
