Abstract
Operating a gaseous hydrogen fuel engine includes controlling an injection timing of a gaseous hydrogen fuel injected into a flow of pressurized intake air so as to produce a leading cooling flow of pressurized intake air into a cylinder in an engine, a trailing purging flow through an intake conduit, and a middle flow of both pressurized intake air and gaseous hydrogen fuel into the cylinder. Undesired combustion such as preignition and/or backfire can be limited. Related apparatus and control logic is also disclosed.
