Abstract
A gaseous fuel engine system includes an engine housing forming a plurality of intake ports, and a plurality of fuel admission tubes oriented to admit a gaseous fuel into the plurality of intake ports. The fuel admission tubes include mixers having flow-impinged surfaces exposed to at least one of a flow of gaseous fuel or a flow of intake air and each including a detachment edge. The mixers may include fins, wedge structures, and/or a contoured outer surface of the fuel admission tube. Related apparatus and methodology is also disclosed.
