Combustion system, nozzle for prechamber assembly, and method of making same

摘要

A nozzle for a prechamber assembly of an engine includes a hollow nozzle body having an outer surface, defining first and second outer openings, and an inner surface, defining an interior chamber and first and second inner openings. The nozzle body defines first and second orifices in communication with the interior chamber. The first orifice extends in a first orifice configuration between the first outer opening and inner opening and defines a first entry path projection extending from the first inner opening into the interior chamber. The second orifice extends in a second orifice configuration between the second outer opening and inner opening and defines a second entry path projection extending from the second inner opening into the interior chamber. The first and second entry path projections intersect at an impingement region in the interior chamber, which is radially offset from a central longitudinal axis of the nozzle.

1. A nozzle for a prechamber assembly of an engine comprising:
a nozzle body, the nozzle body having a mounting end and a distal tip, the nozzle body defining a central longitudinal axis extending between the mounting end and the distal tip, the nozzle body being hollow and including an outer surface and an inner surface, the outer surface defining a first outer opening and a second outer opening, the inner surface defining an interior chamber, a first inner opening, and a second inner opening; and wherein the nozzle body defines a first orifice in communication with the interior chamber, the first orifice extending in a first orifice configuration along a first angle of inclination relative to the central longitudinal axis between the first outer opening and the first inner opening, and the nozzle body defines a second orifice in communication with the interior chamber, the second orifice extending in a second orifice configuration along a second angle of inclination relative to the central longitudinal axis between the second outer opening and the second inner opening, the second angle of inclination being different from the first angle of inclination, the first orifice configuration of the first orifice defining a first entry path projection extending from the first inner opening into the interior chamber, and the second orifice configuration of the second orifice defining a second entry path projection extending from the second inner opening into the interior chamber, the first entry path projection of the first orifice and the second entry path projection of the second orifice intersecting at an impingement region in the interior chamber, the impingement region being radially offset from the central longitudinal axis in a radial plane substantially perpendicular to the central longitudinal axis.
