After the Engine is runing the Ball Pin must become extremely hot and when the Fuel Spray hits it; it is surely an aid in starting combustion. I think the Ball Pin is one of the reasons that the Injectors in a Mercedes seem to last longer than on other Enginges with prechambers. The Ball Pin aids in atomization and when hot ignition of the Fuel even when the Injectors Nozzles are worn and the Fuel Spray is poorly atomizing.

After my first pilgrimage to the holy city of Stuttgart, I got a DVD set that has LOTS of vignettes and a few animations on it. As soon as I figure out how to translate them to an upload-able form, I'll highlight the diesel info in "DD." The ball pin prechambers also induce a swirl turbulence pattern.
