A plurality of injector hold-down clamps () is arranged to connect, one each, each of a plurality of fuel injectors () to an internal combustion engine (). Each fuel injector forms a neck region (), and each clamp surrounds each injector around the neck region, such that a plurality of annular volumes () 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.
