摘要： The present invention is directed to an auxiliary power unit for use with a vehicle, typically a truck. The truck has a cab and a sleeper to which the auxiliary power unit provides auxiliary air conditioning and heating. The truck also has a cab evaporator, a sleeper evaporator, a compressor, a condenser, and a plurality of refrigerant lines, a cab heater, a sleeper heater, and a plurality of coolant lines. The auxiliary power unit has an auxiliary evaporator and a plurality of auxiliary refrigerant lines. The auxiliary evaporator is arranged in series with the sleeper evaporator and the sleeper heater. The auxiliary refrigerant lines are separate and distinct from the truck's plurality of refrigerant lines. The auxiliary power unit also has a plurality of auxiliary coolant lines which are interconnected with the truck's plurality of coolant lines. The interconnection is accomplished in such a way that the auxiliary power unit can provide heat to the sleeper heater when the truck engine is running or when the truck is not running. If the coolant becomes excessively hot, a by-pass thermostat and valve direct the coolant to an auxiliary radiator. The auxiliary power unit has an auxiliary control panel in the sleeper to provide control of the heating and cooling in the sleeper when the truck engine and/or auxiliary engine is running.
摘要翻译：本发明涉及一种用于车辆（通常是卡车）的辅助动力单元。叉车有一个驾驶室和一个卧铺，辅助动力单元提供辅助空调和加热。卡车还具有驾驶室蒸发器，卧铺蒸发器，压缩机，冷凝器和多个制冷剂管线，驾驶室加热器，卧铺加热器和多个冷却剂管线。辅助动力单元具有辅助蒸发器和多个辅助制冷剂管线。辅助蒸发器与卧铺蒸发器和卧铺式加热器串联布置。辅助制冷剂管线与叉车的多个制冷剂管线是分离的和不同的。辅助动力单元还具有多个辅助冷却剂管线，这些辅助冷却剂管线与卡车的多个冷却剂管线相互连接。互连是这样完成的，即当卡车发动机运行时或当卡车不运行时，辅助动力单元可以向卧铺加热器提供热量。如果冷却液变得过热，旁路恒温器和阀将冷却剂引导到辅助散热器。辅助动力单元在轨枕中具有辅助控制面板，以在卡车发动机和/或辅助发动机运行时提供对卧铺的加热和冷却的控制。

摘要： A system is disclosed including a primary engine that provides vehicle propulsion and a secondary engine that drives a generator to provide auxiliary power. The system further includes a first exhaust gas passageway from the primary engine and a second exhaust gas passageway from the secondary engine. The system further includes an emission treatment device including an exhaust inlet to treat exhaust from the primary and secondary engines. The system further includes an exhaust routing device that selectively routes exhaust from the first passageway or the second passageway to the exhaust inlet. The exhaust routing device at least partially blocks the first passageway or the second passageway from fluid communication with the exhaust inlet.
