Abstract: Apparatuses for immobilizing fuel injection apparatuses are disclosed. A coupling member couples a fuel injection apparatus with an injector body of an engine. The coupling member includes a top surface, a bottom surface, a side surface, and an opening extending from the top surface to the bottom surface. The opening receives the fuel injection apparatus. The coupling member also includes a protruding portion extending from the bottom surface or the side surface which comes into contact with the injector body to prevent rotational movement of the fuel injection apparatus.

Abstract: The present disclosure provides a fuel injector, comprising: a body including a plurality of body alignment features; a nozzle including a plurality of nozzle alignment features and a plurality of nozzle holes for injecting fuel; and a plurality of alignment guides configured to mate with the plurality of body alignment features and the plurality of nozzle alignment features to align the nozzle with the body such that the plurality of nozzle holes is in a desired orientation relative to the body.

Abstract: An injector combustion shield assembly comprising a bore configured to receive a fuel injector, the bore including a fluid opening in fluid communication with a fluid jacket and a fluid outlet positioned within an annular wall of the bore; and a valve positioned between the fluid jacket and the fluid opening and configured to selectively permit a fluid from the fluid jacket to enter the bore, the valve being movable between an open configuration to permit fluid flow from the fluid jacket into the bore via the fluid opening and a closed configuration to prevent fluid flow from the fluid jacket into the bore.
