Abstract
A fuel injector that comprises a parallel circuit fuel filtration circuit providing filtered fuel to the control valve. Specifically, a fuel filter is positioned inside the injector within the passage leading to the control valve. Debris is removed from the fuel and filtered fuel is allowed to pass through to the control valve. Unfiltered fuel may be purged from the fuel injector during injection. Alternatively, unfiltered fuel may be removed from the injector via the drain.
