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.
