Swirl Prechambers - Actros617 - 06-13-2010 Anyone tired this on a OM617??? Is there any swirl prechamber that will fit into a OM617 RE: Swirl Prechambers - ForcedInduction - 06-14-2010 The factory PC is swirl by design. RE: Swirl Prechambers - winmutt - 06-14-2010 I think hes referring to the rotated hotspot and off center spray in the om 60x chamber. RE: Swirl Prechambers - ForcedInduction - 06-14-2010 He would need to machine new lower injector bodies to fit the new thread pitch.

I thought the problem would be more in the prechamber? In the om60x don't they sit at and angle in relation to the engine? Looked for an image in the W124 fsm without much luck. RE: Swirl Prechambers - Captain America - 06-14-2010 Ooooooooooooooooooooooooo! thats a sexy injector! RE: Swirl Prechambers - ForcedInduction - 06-14-2010 The angle is in the collar. Problem is the swirl engines use different thread lines as well so the injectors aren't a straight swap like the prechamber. RE: Swirl Prechambers - Actros617 - 06-15-2010 How about using a OM60x injectors instead of modifying it???

Problem is the swirl engines use different thread lines as well so the injectors aren't a straight swap like the prechamber. the PC aren't straight swap either. One thing is to cut/unscrew them and combine a lower part 617a with the upper part of an 60x somehow. Don't know about the outer diameter but it is doable. Tom RE: Swirl Prechambers - Einar - 06-15-2010 I think early 60X-injectors and 61X-injectors have almost the same body and treads, or am I far away? I have a loose 603A-head if anyone want some info, but I havent got enough power to loosen the PC`s.

The 602/603 we are talking about with the angled prechambers are only found in the 1989+ W140 and 300D 2.5 models (in the US).

RE: Swirl Prechambers - winmutt - 06-15-2010 That was the cut away I was looking for. RE: Swirl Prechambers - ConnClark - 06-16-2010 The impingement pin is also essential to getting the air to swirl. I believe in 1987 Mercedes did angle the bottom of the pin in the OM603 to reap some of the benefits. RE: Swirl Prechambers - Einar - 06-16-2010 AHA, I forgot the "Diesel-Facelift" in `89. |
