Fuel Combustion System Having Component with Knurled Conduction Surface and Method of Making Same

摘要

A component of a fuel combustion system of an engine includes a body with a knurled conduction surface. The body is hollow and defines a central longitudinal axis. The body includes an outer surface, an inner surface, and an orifice surface. The outer surface defines an outer opening. The inner surface defines an interior chamber and an inner opening. The orifice surface defines an orifice passage extending between, and in communication with, the outer opening and the inner opening. The orifice passage is in communication with the interior chamber via the inner opening. The outer surface includes the knurled conduction surface. The knurled conduction surface has a boundary surface and a plurality of protrusions that project outwardly from the boundary surface. At least a portion of the knurled conduction surface is axially aligned with the interior chamber along the central longitudinal axis.
