ABSTRACT:
A method for increasing and/or suppressing a natural frequency of a fuel injector feed strip while increasing in the axial direction the flexibility of the feed strip, without the use of additional structure or damping devices. More particularly, and by way of example, the present invention provides a fuel feed strip that is shaped in a shape corresponding to a first vibration mode (e.g., a bow shape) of a fuel feed strip of a desired shape (e.g., a straight fuel feed strip). By forming the fuel feed strip in a shape corresponding to a first vibration mode of the fuel feed strip of a desired shape, a vibration mode of the fuel feed strip is suppressed while the axial flexibility of the fuel feed strip is increased.
