    Abstract: A fluid injection system includes a fluid injector assembly; a fluid conditioning module having an outlet port that is fluidly coupled to an inlet port of the fluid injector assembly; an injector assembly outlet conduit fluidly coupled to an outlet port of the fluid injector assembly and disposed downstream of the fluid injector assembly, the injector assembly outlet conduit defining a pressure measurement port and a flow-restricting orifice, the pressure measurement port being disposed upstream of the flow-restricting orifice along the direction of fluid flow through the fluid injector assembly; a pressure sensor fluidly coupled to the pressure measurement port; and a controller operatively coupled to the fluid conditioning module and the pressure sensor. The controller is configured to adjust a flowrate of a fluid through the injector assembly inlet conduit based on a pressure signal from the pressure sensor.

    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: An electronically controlled fuel injector includes an injection valve; a control valve fluidly connected between a pressurized fuel supply passage and a control chamber for controlling operation of the injection valve, the control valve movable between a non-injection position and an injection position; the injection valve configured to inject fuel with the control valve in the injection position; and a control member chamber including an orifice that fluidly connects the control member chamber with a low pressure return line of a fuel supply system. The control chamber is fluidly coupled with a pressure communication passage such that the control chamber is fluidly coupled with the low pressure return line through the orifice in the control member chamber when the control valve is in the injection position. The pressure communication passage includes a two-way, variable flow rate valve.

    Abstract: A fuel injector is disclosed. The fuel injector may have an injector body having a fuel inlet and at least one orifice. The fuel injector may also have a first check valve member. The first check valve member may be selectively movable to fluidly block a first flow of fuel from the fuel inlet to the at least one orifice. The fuel injector may have a second check valve member. The second check valve member may be selectively movable to fluidly block a second flow of fuel from the fuel inlet to the at least one orifice. The fuel injector may also have a control valve assembly. The control valve assembly may be configured to selectively operate either the first check valve or both the first check valve and the second check valve to fluidly connect the fuel inlet and the at least one orifice.

    Abstract: An asymmetrical orifice for bypass control in a clean fuel module may include a body having first and second end surfaces and an inner surface defining a bore through the body extending from a first opening through the first end surface to a second opening through the second end surface. The first opening has a first opening inner diameter and the second opening has a second opening inner diameter that is less than the first opening inner diameter. The asymmetrical orifice also includes a flow control contour in the second end surface surrounding the second opening of the bore. The configuration may give the asymmetrical orifice a first discharge coefficient for fluid flowing from the first opening to the second opening that is greater than a second discharge coefficient for fluid flowing in a second direction from the second opening to the first opening.
