A prechamber assembly for an internal combustion engine is disclosed. The prechamber assembly may have a prechamber housing with a first prechamber housing portion and a second prechamber housing portion. The first prechamber housing portion and the second prechamber housing portion may define a prechamber volume. The prechamber assembly may also have a cooling system. The cooling system may be configured to cool at least one of the first prechamber housing portion and the second prechamber housing portion based on a flow of a cooling fluid through the cooling system. The cooling system may have at least one cooling channel formed within the prechamber housing.

Prechamber assembly for internal combustion engine

A pre-chamber body for an engine is disclosed. The pre-chamber body may have a pre-chamber. The pre-chamber body may also have flow transfer channels fluidly connecting the pre-chamber and an exterior of the pre-chamber body. Each flow transfer channel extends along a flow transfer channel axis (B) from an inner opening via a throat section to an outer opening. A cross-section of the flow transfer channels converges from a first cross section (A) of the inner opening to a second cross-section (A) of the throat section and diverges from the second cross-section (A) to a third cross-section (A) of the outer opening along the flow transfer channel axis (B). At least one of the inner opening and the outer opening has an oval shape with a maximum diameter (a, a) and a minimum diameter (b, b), the maximum diameter (a, a) being greater than the minimum diameter (b, b).

Pre-chamber of an internal combustion engine

A pre-chamber body for an internal combustion engine is disclosed. The pre-chamber body may have a pre-chamber. The pre-chamber body may also have a flow transfer passage, which may fluidly connect the pre-chamber and an exterior of the pre-chamber body. In addition, the pre-chamber body may have at least one backflow channel, which may fluidly connect the pre-chamber and the flow transfer passage.
