Embodiment Construction

[0046] figure 1 A first exemplary embodiment of a pre-chamber arrangement according to the teachings of the present disclosure is shown in cross-sectional view. The pre-chamber arrangement 1 comprises a pre-chamber body 13 and a nozzle body 14 extending from the pre-chamber body 13 and arranged at one axial end of the pre-chamber arrangement. The axis of the prechamber arrangement is indicated at 11 . A pre-chamber cavity 12 is formed inside the pre-chamber arrangement and extends axially into the nozzle body forming the interior of the nozzle body. A nozzle opening 15 is provided in the nozzle body 14 and provides fluid communication between the interior of the nozzle body and the exterior of the nozzle body. The pre-chamber cavity 12 is delimited by walls circumferentially and at the nozzle-side axial end. It is to be noted that the pre-chamber arrangement 1 is open at an axial end opposite the nozzle body to receive ignition means, such as a spark plug, in the pre-chambe...

Abstract

Disclosed is a prechamber device (1) for an internal combustion engine. The prechamber device comprises a prechamber body (13) circumferentially enclosing a prechamber cavity (12), a nozzle body (14)extending from the prechamber body and disposed at a first axial end of the prechamber device, wherein an interior of the nozzle body is in fluid communication with and provides an appendix of the prechamber cavity (12). The prechamber body and the nozzle body are provided as a wall comprising an inner surface (16) and an outer surface (17) and comprise a first material. A core member (18) of a second material is enclosed inside the wall between the inner surface and the outer surface and axially extending inside the nozzle body (14), enclosed by the first material.

Description

technical field [0001] The present disclosure relates to a pre-chamber arrangement for an internal combustion engine as set forth in the claims. The disclosure further relates to a cylinder head and a reciprocating engine as further set forth in the claims, and to a method of manufacturing a pre-chamber arrangement. Background technique [0002] Certain types of internal combustion engines, particularly reciprocating internal combustion engines, are equipped with a pre-chamber that facilitates rapid and complete ignition of the fuel-oxidizer mixture provided in the combustion chamber. In the pre-chamber cavity, part of the cavity's fuel-oxidizer mixture is ignited by an ignition source such as, for example, a spark plug. The pre-chamber device enclosing the pre-chamber cavity comprises nozzle openings at one axial tip of the pre-chamber device through which jets of combusted mixture and / or hot combustion products and / or plasma are discharged into In the main combustion cha...
