MULTI-FUEL INJECTOR WITH FUEL MIXING

A fuel injector is capable of injecting a plurality of different fuels in a single fuel injection event, the fuel injector including: a nozzle at an end of the fuel injector, the nozzle having a tip, openings in the tip of the nozzle through which fuel is configured to be injected, and a check valve member with a tip located within the nozzle, the check valve member being movable between an injection position in which fuel is injected via the openings and a closed position in which the openings are closed. The fuel injector further includes a primary fuel path within the fuel injector, a pilot fuel path within the fuel injector, and a mixing volume connecting the primary fuel path and the pilot fuel path when the check valve member is in the closed position.
