Precombustion chambers

Viesti Kirjoittaja Forced_Induction »

Is it possible, or even necessary, to modify the precombustion chambers?

Enlarge the openings?
Coat inside with a ceramic insulating paint?
Machine the injector seat to sit deeper inside?

The idea is to make the air flow in/out of the prechamber more efficiently, and allow more air to be compressed into the prechamber.

No opinions?

The holes are three 4mm holes on the front, two 3mm on the back, and one 2mm facing the piston.

Would there be any advantage to increasing the prechamber flow or do they need to stay restricted?

No need to modify them.

I saw in the local yard an Audi 5000 turbodiesel. The injectors look like the Mercedes ones, but I am told they supposedly flow more. I plan on yanking them and perhaps the fuel pump too. I may try to see if I can yank the precombustion chambers and see if they are any different from ours.
