Abstract: A fuel injector is disclosed for use in an engine system. The fuel injector may have a body defining a gas inlet, an oil inlet, and an oil outlet. The fuel injector may also have a nozzle connected to the body and having a base end in fluid communication with the gas inlet, and an injection tip located opposite the base end. The fuel injector may also have a valve check disposed in the nozzle and movable to selectively block and unblock the injection tip of the nozzle, and a plunger disposed in the body between the oil inlet and the oil outlet. The plunger may be movable between a flow-passing position and a flow-blocking position to cause movement of the valve check through the injection tip. The injector may further have a solenoid actuator configured to selectively move the plunger.

Abstract: A fluid conditioning system includes a first filter mount having a first filter inlet port and a first filter outlet port; a motor unit; a recirculation pump unit operatively coupled to the motor unit, an outlet of the recirculation pump unit being fluidly coupled to the first filter inlet port via a first filter inlet conduit, an inlet of the recirculation pump unit being fluidly coupled to the first filter outlet port via a first filter outlet conduit; a second filter mount having a second filter inlet port; and a delivery pump unit operatively coupled to the motor unit. The inlet of the delivery pump unit is fluidly coupled to the first filter outlet port via the first filter outlet conduit, and the outlet of the delivery pump unit is fluidly coupled to the second filter inlet port via a second filter inlet conduit.
