Abstract
A fuel injector assembly for an engine system includes a fuel pressurization mechanism, a fuel injector, and a flow-directing sleeve positioned about the fuel injector and including sealing surfaces for sealing with a cylinder head and with an injector body. Slots are formed at least in part in the sealing surfaces to direct fuel from the cylinder head into an incoming cooling passage extending to the fuel pressurization mechanism, and from an outgoing cooling fuel passage into the cylinder head.
