Abstract: An exhaust system for a power system contained in an engine compartment. The exhaust system includes a mount for two or more exhaust treatment devices and an enclosure surrounding the two or more exhaust treatment devices. The enclosure defines a space with a higher temperature than a space defined by the engine compartment during steady state operation of the power system. At least one electronic or fluid device is coupled to the enclosure or mount and located on an exterior of the enclosure.

Abstract: Systems, methods and tools are disclosed for releasing pressure from closed systems. For example, in a SCR system, diesel emission fluid (DEF) can become over pressurized as it is pumped between a DEF pump and a DEF injector. A manifold may be disposed between the pump and injector. The manifold or passageway that communicates the DEF between the pump and injector includes a service port. A plug is disposed between the DEF passage and the service port or on a seat disposed between the DEF passage and the service port. A specially designed tool is employed to dislodge the plug from the seat and release pressure in the DEF passage through the tool and, optionally, through a drain hose connected to a distal end of the tool.
