GASEOUS FUEL MIXER

摘要

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.

1. A mixing device for introducing gaseous fuel into an intake airflow of an engine, the mixing device comprising:
an inlet provided at a first end; an outlet provided at a second end; an intake passage extending between the inlet and the outlet for directing the intake airflow toward the engine; an annular channel at least partially encircling the intake passage; a plurality of fuel supply manifolds, each coupled to a main gaseous fuel inlet of the mixing device; a separate plurality of gaseous fuel injectors coupled to each one of the plurality of fuel supply manifolds, each separate plurality of gaseous fuel injectors arranged to receive gaseous fuel from the corresponding one of the plurality of fuel supply manifolds, wherein the annular channel is configured to receive gaseous fuel injected from all of the separate pluralities of gaseous fuel injectors; and a diffuser positioned along the intake passage, the diffuser being arranged to receive gaseous fuel from the annular channel and operable to diffuse gaseous fuel from the annular channel into the intake airflow in the intake passage.
