Fuel Combustion System, Nozzle for Prechamber Assembly Having Coolant Passage in Communication with Orifice Passage, and Method of Making Same

摘要

A nozzle for a prechamber assembly of an engine includes a hollow nozzle body which includes an outer surface, an inner surface, and an orifice surface. The outer surface defines an outer orifice opening and a coolant passage inlet opening. The inner surface defines an interior chamber and an inner orifice opening. The orifice surface defines an orifice passage extending between, and in communication with, the outer orifice opening and the inner orifice opening. The orifice passage is in communication with the interior chamber via the inner orifice opening. The orifice surface defines a coolant passage outlet opening which is in communication with the orifice passage. The nozzle body includes a coolant surface which defines a coolant passage within the nozzle body. The coolant passage extends between the coolant passage inlet opening and the coolant passage outlet opening and is in communication with the orifice passage.
