Abstract
A nozzle for a prechamber assembly of an engine includes a nozzle body which is hollow and includes an outer surface, an inner surface, and an orifice surface. The outer surface defines an outer orifice opening, and 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 nozzle body includes a coolant surface which defines a coolant passage within the nozzle body. The coolant surface includes an orifice interface portion disposed adjacent the orifice surface such that the orifice surface and the orifice interface portion of the coolant surface are in heat-transferring relationship with each other.
