F02M 51/00

US Classification:

239 5, 239 88, 2395338, 2395851

Abstract:

A common rail fuel injector includes a needle valve member that moves to open and close nozzle outlets for a fuel injection event responsive to pressure in a needle control chamber. Between injection events, the needle control chamber is fluidly connected to the fuel inlet by a first pathway that includes a Z orifice, and fluidly connected to the fuel inlet by a second pathway that includes an F orifice, an intermediate chamber and an A orifice. During an injection event, the needle control chamber is fluidly connected to a drain outlet by a third pathway that includes the A orifice, the intermediate chamber and an E orifice. Different performance characteristics are achieved by adjusting the sizes of the respective of F, A, Z and E orifices.

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

B05B 1/30

US Classification:

2395855, 239 5, 239462

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.

International Classification:

F02M 69/54
F16K 17/20

US Classification:

123457, 137469

Abstract:

A pressure relief valve is provided for a common rail fuel system. The pressure relief valve has a housing with an inlet, an outlet, and a central bore fluidly connecting the inlet and the outlet. The pressure relief valve also has a single valve seat and a first valve element movable to selectively block a flow of fluid through the single valve seat. The pressure relief valve further has a second valve element disposed within the central bore of the housing and movable to selectively block a flow of fluid through the central bore.

International Classification:

F02M 63/00
B05B 1/30

US Classification:

123447, 239584

Abstract:

A pressure balancing orifice plate for a fuel injector device may include a cylindrical body having a top surface, a bottom surface, an annular outer surface, and a body longitudinal axis, a balance pressure relief orifice extending from the top surface to the bottom surface, and a raised valve seat extending upwardly from the top surface and surrounding the balance pressure relief orifice. The valve seat may have a central seat surface encircling the balance pressure relief orifice and a plurality of leaf portions extending radially outwardly from the central seat surface and defining drainage channels there between. A width Wof the drainage channels may increase as the radial distance from the balance pressure relief orifice increases.

International Classification:

F02D 1/00

US Classification:

239 5, 2395332, 2395851

Abstract:

A fuel injector for an engine is disclosed. The fuel injector may have a fuel nozzle with at least one injection orifice, and a needle element movable within the fuel nozzle between a first position at which the needle element inhibits fuel flow and a second position at which fuel flow is substantially uninhibited. The fuel injector may also have a control chamber located at a base end of the needle element, a body, and a control valve disposed within the body and movable to selectively drain the control chamber, thereby causing the needle element to move between the first and second positions. The fuel injector may further have an armature disposed within an armature cavity of the body and selectively energized to move the control valve, and a pressure reducer disposed within the body and configured to reduce a pressure of the armature cavity.

Abstract:

Fuel is injected by energizing a solenoid of a fuel injector for an on-time that terminates at a first end-of-current timing. An end-of-current trim is determined at least in part by estimating a duration between an induced current event in a circuit of the solenoid and a valve/armature interaction event. An induced current event occurs when an armature abruptly stops, and a valve/armature interaction event occurs when the armature couples with or de-couples from the valve member. Fuel is injected in a subsequent injection event by adjusting the end-of-current timing by the end-of-current trim.
