Abstract: The present disclosure provides a fuel injector for an internal combustion engine with a fuel injector body having a valve chamber, a first conduit in fluid communication with the valve chamber for a first flow of fuel having a first pressure, and a second conduit in fluid communication with the valve chamber for a second flow of fuel having a second pressure. The fuel injector further includes a valve member configured to move between the first conduit and the second conduit. Additionally, an actuator of the fuel injector is configured to move the valve member during a fuel injection cycle. The fuel injector is configured to operate in at least three modes.
