(02-19-2017, 11:13 AM)erx(02-19-2017, 10:06 AM)Hario(02-17-2017, 05:10 PM)erx Did you pop test injectors before changing nozzles? Were they bad? If prechambers have ball inside in place and no visual defects then they must work.
Few years ago when I starter my build I ran with small 8cm hy35 and let boost too high so EGT melted injector seal washers and only one injector popped normally on 135bar, others where squirting without pop and nozzle tips were clogged so spray pattern was awful. On cold start engine was lumpy few seconds and knocking a little more than normal but it was almost ok when warm, no smoking. I changed nozzles @150bar and washers and I have run the same engine for years and still the same prechambers and engine itself never opened. What is your pump timing?
Ok thank you for the info, I got rebuilt injectors for a steal @ £25gbp each so I have not checked mine yet, my friend has a pop tester so I will check my old ones to see spray pattern and pressure to confirm they are bad. Will rebuild them @150bar pop then swap back also.
It is my daily so have to be like this unfortunately. Pump timing not moved from when I first got engine when it ran sweet, so I don't suspect, and it is splined to can't have slipped.
Even when warm it runs lumpy, idles fine after a hard run then deteriorates - Presumably from prechambers and injectors cooling down and then bad fuel atomisation is not hidden anymore by heat evaporating un-atomised fuel.,
Should run fine now but flattened battery from having music playing for 2 days during the swap lol, tbc..
Cheers,
Engine worked fine when you first got it and suddenly injectors and prechambers are not working. It doesn't make sense, this kind of things don't happen over night. Also there's no such thing as prechamber cooling down when engine warm and working. I belive you have other problem like maybe air in fuel system, dust in pump delivery valves, if you take off injector lines or any other fuel system parts then you have to keep it extremely clean.
No I mean it deteriorated over the 20k miles of my ownership, replaced DV washers and O-rings with no change, so we will see in the morning if it is fixed now,
Installed:
OM606/722.6, big IC, W220 brakes.
Planned:
DIY manifold, compound, 722.6 controller, built IP.
