Abstract
A mixing device for introducing gaseous fuel into an intake passage of an engine, including a body, an annular channel within the body at least partially encircling the intake passage, the body defining a fuel inlet opening. The mixing device includes a plurality of gaseous fuel injectors arranged to discharge gaseous fuel into a fuel inlet manifold, a fuel connection passage extending between the fuel inlet manifold and the fuel inlet opening of the body, a diffuser positioned within the body to diffuse gaseous fuel from the annular channel into the intake airflow, and a valve positioned along the fuel connection passage and configured to selectively block fluid communication between the fuel inlet manifold and the fuel inlet opening of the body in response to a signal from at least one electronic controller programmed to execute control strategies controlling operation of the engine, the gaseous fuel injectors, and the valve.
