  • Injector cooling apparatus
    Patent number: 9267410
    Abstract: A cooling system for an injector tip for a diesel emission fluid (DEF) injection system is disclosed. The system uses a heat sink, such as a head for a regeneration system, to vaporize cooling fluid, in combination with a phase separation tank, to force cooling fluid backward through a cooling loop thereby allowing cooling of an injector tip following engine shutdown in a “hot” shutdown situation.
    Type: Grant

  • Emissions system mounting device with reductant mixing
    Publication number: 20100186382
    Abstract: An emissions control system is disclosed. The emissions control system may have a first exhaust treatment device. The emissions control system may also have an end cap defining a mixing chamber connected to an end of the first exhaust treatment device. The mixing chamber may be configured to promote mixing between a flow of exhaust received from the first exhaust treatment device and a reductant. The emissions control system may further have a second exhaust treatment device configured to receive the flow of exhaust and reductant after it passes through the mixing chamber.
