Abstract
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).
