Abstract
A fuel injector has a seat and at least one seat passage. The seat includes an outer tip surface through which the seat passage extends. Fin structure is provided in the outer tip surface and is constructed and arranged to increase a surface area of the outer tip surface as compared to a surface area of the outer tip surface absent the fin structure. The outer tip surface, including the fin structure, is constructed and arranged to be heated by combustion gases so that the outer tip surface reaches a temperature greater than a temperature that the outer tip surface would reach absent the fin structure, so as to cause evaporation of fuel that contacts the outer tip surface.
