ABSTRACT:
A method is disclosed for forming a fuel feed passage in the feed arm of a fuel injector. The method includes the steps of providing a fuel feed passage in the feed arm of a fuel injector, whereby the fuel feed passage has an initial cross-sectional flow area that corresponds with an initial fuel flow velocity, an initial convection heat transfer coefficient and initial localized wetted wall temperatures for the fuel feed passage, for a given fuel flow rate and fuel temperature. The method further includes decreasing the initial cross-sectional flow area of the fuel feed passage so as to increase the fuel flow velocity and the convection heat transfer coefficient for the fuel feed passage, while lowering the localized wetted wall temperatures for the fuel feed passage, without varying the given fuel flow rate and fuel temperature.
