  • 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
