PRE-CHAMBER OF AN INTERNAL COMBUSTION ENGINE

The present disclosure relates to a pre-chamber body (26) for a gaseous fuel internal combustion engine (1). The pre-chamber body (26) comprises a pre-chamber (34) and a a plurality of flow transfer channels (22). Each flow transfer channel (22) extends along a flow transfer channel axis (B) from an inner opening (48) via a throat section (54) to an outer opening (50). A cross-section of the flow transfer channels (22) converges the inner openings (48) to the throat sections (54) and diverges from the throat sections (54) to the outer openings (50) along the flow transfer channel axis (B). At least one of the inner opening (48) and the outer opening (50) has an oval shape.
