A gas fuel system for a bi-fuel engine includes an injector block assembly that supports gas fuel injectors between an injector block and an inlet header. The block assembly may be mounted beside or behind the engine remote from the engine intake ports where gasoline fuel or gaseous fuel (gas ) may be injected for powering the engine. The block assembly connects the injectors through individual distribution lines with separate port openings of an adapter plate mounted between the air intake manifold and the engine intake ports to provide for injection of gas to the intake ports from the remote location. Mounting of the injectors in the remote block assembly, which feed s the adapter, avoids changes to a developed gasoline fuel system in the engin e, thus reducing development and production costs. The block assembly may also be modified to use other available gas injectors without affecting the conventional engine components. |
