Abstract
An engine head assembly includes a plurality of fuel injectors each positioned within a fuel injector bore in an engine head, and fluidly coupled with a fluid conduit. Each fuel injector includes a valve assembly within a fuel injector case such that an interior fluid space is formed between the fuel injector case and the valve assembly. The fuel injector case includes an elongate body having a particulate-blocking perforation array formed therein, and that is structured to block particulates in fuel entering the fuel injector from the fluid conduit.
