Abstract
A nozzle for a prechamber assembly of an engine includes a nozzle body. The nozzle body is hollow and includes an outer surface and an inner surface. The outer surface defines an outer opening, and the inner surface defines an interior chamber and an inner opening. The nozzle body includes an orifice surface which defines an orifice passage extending between, and in communication with, the outer and inner openings. The orifice passage is in communication with the interior chamber via the inner opening. The orifice surface is continuously curved. The inner surface of the nozzle body can include a groove surface that is contiguous with the orifice surface. The groove surface defines an orifice groove in communication with the interior chamber and with the orifice passage.
