My understanding of the angled prechambers is that the ball shaft was also off set from the center axis of the burn tube to help create a directional swirl rotation.
If I remember correctly, (I need to review this thread to be sure), the injector was angled to spray with the rotation, which I think would help the fuel travel with the rotating air, resulting in better distribution.
Also I can picture the nozzle getting fresher air rotating past it for longer because with the angled spray, fuel isn't necessarily blown and burnt up stream of swirl until later in the injection.
That is all I got.
Anyone?
