Abstract: An injector head for a fuel injector of an engine includes an injector body configured to be coupled with a fuel stem of the fuel injector. The injector body extends orthogonally relative to the fuel stem. The injector body extends axially along a central axis and circumferentially about the central axis. The injector head also includes a central fuel assembly. The central fuel assembly includes a tip portion disposed proximal to a downstream end of the injector body. The tip portion includes an end portion, an intermediate portion, a plurality of support pins extending between the end portion and the intermediate portion, and a plurality of fins extending radially-outward and from the intermediate portion along the central axis. The injector head is formed by additive layer manufacturing. The plurality of support pins and the plurality of fins provide support for forming the injector head by additive layer manufacturing.
