Abstract
A mixing device for introducing gaseous fuel into an intake airflow of an engine, the mixing device including an inlet, an outlet, an intake passage extending between the inlet and the outlet, an annular channel, and a plurality of fuel supply manifolds, each coupled to a main gaseous fuel inlet of the mixing device, and a separate plurality of gaseous fuel injectors coupled to each one of the plurality of fuel supply manifolds to receive gaseous fuel from the corresponding fuel supply manifold. The annular channel is configured to receive gaseous fuel injected from all of the separate pluralities of gaseous fuel injectors. The mixing device includes a diffuser, the diffuser arranged to receive gaseous fuel from the annular channel and operable to diffuse gaseous fuel from the annular channel into the intake airflow.
