  • Cooling arrangement for a fuel injector and method
    Patent number: 7703421
    Abstract: A plurality of injector hold-down clamps (310) is arranged to connect, one each, each of a plurality of fuel injectors (106) to an internal combustion engine (100). Each fuel injector forms a neck region (212), and each clamp surrounds each injector around the neck region, such that a plurality of annular volumes (604) is defined, one each, between the neck region of each injector and each injector clamp. Each annular volume collects a quantity of lubrication oil during operation of the internal combustion engine such that the volume of oil collected in each respective annular volume removes heat from the respective fuel injector.
    Type: Grant
