Abstract
An apparatus and method for minimizing and/or preventing thermal degradation of fuel in a fuel injector is disclosed. The body of the injector includes a fuel gallery with a contoured scarf formed therein. The scarf is configured to minimize and/or prevent fuel recirculation thus reducing the likelihood that fuel will dwell in an area long enough to sufficient to cause the degradation of the fuel.
