摘要： A fuel injector wherein a cylindrical surface supports an electrical heating structure covering 360° or almost 360° of the surface for heating fuel. The structure comprises a first dielectric layer adhered to the surface; a thick film resistance heating element; a second dielectric layer; spaced-apart first and second conductor pads, wherein the first conductor pad is disposed in contact with a dielectric layer and a first end of the heating element, and wherein the second conductor pad is disposed in contact with a dielectric layer and a second end of the heating element. Another dielectric layer may be disposed over the preceding layers and the first and second conductor pads and having first and second windows formed therein for access to the first and second conductor pads. The resistance heating element may selectively be trimmed by overprinting in a pattern one or more times to improve the uniformity of heating.

摘要： A lower fuel injector filter includes a generally planar disk having an annular shape and including a plurality of filter holes. The disk is retained by a valve guide within a valve seat. The disk prevents internally generated contamination particles contained in fuel flowing through the filter holes from reaching a valve and seat interface positioned downstream of the valve guide. The disk may also be retained by a ball valve stop proximate the valve seat.

摘要： A lower filter for a fuel injector includes a disk having an annular shape and including a plurality of filter holes. The disk is positioned upstream of a valve guide of an internal valve assembly without contacting the valve guide. The disk prevents internally generated contaminants contained in fuel flowing through the filter holes from reaching a valve guide area and a sealing area of the internal valve assembly. By installing the lower filter upstream of the valve guide and without contact to the valve guide, interference with the guidance and reciprocal movement of the valve is avoided. Application of the lower filter in fuel injectors may reduce the occurrence of injector failures by reducing the number of stuck open conditions in injectors and by reducing the number of hydro lock engine incidents without interference with the valve guide.

摘要： An internal lower filter for a fuel injector includes a self-supporting guide guiding a reciprocably activated valve of an internal valve assembly of a fuel injector and a plurality of filter holes formed in said guide filtering fuel flowing through the fuel injector and preventing contaminants contained in the fuel from entering a sealing area of the internal valve assembly. Incorporating the guide filter in accordance with the invention in a fuel injector enables capturing particles or contaminants, generated within the fuel injector during assembly or during operation, before entering the sealing area of an internal valve assembly. Accordingly, failure modes of the injector, such as a stuck open condition that may lead to a hydraulic lock of the engine, can be reduced. By forming the filter holes in a typically used ball guide, no changes are required to the currently used assembly line equipment or the current assembly process.
