ever do anything in Alaska?
I worked in the the oil/gas feilds for a good while, almost 10 years
the AK pipeline pump stations prime movers (pumps/cmpressors/etc.) are all RR, I did some consulting for Alyeska Pipeline, the operator

Currently an operations manager for a Canadian oil & gas company but spent 12 years of my career within the industrial gas turbine dvision of Rolls-Royce. Been a while since I got my hands dirty with a turbine (around 7-8 years) but for the latter part with Rolls-Royce I was working within the design team on fuel control systems for RB-211 and Avon engines both conventional combustion and dry low emissions (DLE) variants plus got some exposure to the Trent DLE package. Was employed out of Ohio but travelled and spent some time in Ansty near Coventry before moving up to Aberdeen.

My experience is mainly with GE units Frame 3 to 9.

Nothing in Alaska I'm afraid, closest I got was the RR test beds in Montreal however did get involved in the units for the TCPL pipeline across Canada. Most of my work was Europe and Asia. Managed to avoid West Africa and the Middle East as they tend not to be too interested in lower emissions!

Never got my hands on any of the proper industrial kit just the aeroderivative industrials. Current North Sea platforms that I/my company manage run LM's (2500 and 5000).

I noticed that the box flap is very 'sticky', it binds...I wondred if the actuator hung up at times?
I greased the pivot points and the flap circumference

This is a quarterly (every 3 months) check procedure for me, the first time I serviced the flap it was very stiff. now it opens a lot smoothly. I recommend doing this if you have not already done so, esp on higher mileage examples.

Ok sonny, not upto speed on the lubrication of the flap.
How do we do that ....

[sonny]

Easy, as said take airbox apart, remove filter, and you will see the flap, the flap will move, identify where the hinges are, and apply wd40/lube on these parts. flap moves a lot easier now. I used a drop of WD40 remembering to clean the area afterwards. this is nothing new, guys on here have been doing this for some time now.

good post, that is pretty much what I did...I put a dab of grease on the pivot points also...

Serious question for the technically gifted.

Carbon Build up is known issue with ALL DFI engines (Porsche, BMW & Audi for example).

Is it right that that some hardly suffer (Porsche, BMW?) and others suffer more?

Did the early DFI engines suffer more than the newer generations?

There are three live carbon threads on the go at the moment, with postings today. They run to 38 pages or 537 posts. Why resurrect something that's been untouched for 6 weeks?

Good question.

Generic question on a generic thread that has been running for a few months. The others are quite specific.

Carrying this on is most disruptive, harmful and harrasing behaviour.

Spare yourself the anguish , and don't read this thread that did not have a finite shelf life.

Do you know if the latest DFI engines are different/better to the earlier ones. I would expect them to be. And the learrning curve may be different for different manufacturers.

if you are 'serious' you would not pre-suppose a 'problem' and taint the question as follows:

first, 'issue' implies 'problem', imo it's not
naturally occuring phenomena or process by-product are more accurate terms

'suffer' is the same 'slanted' and non-technical verbage
do all DI engines 'produce' deposits?
yes, to one degree or another...
I have seen pics for VW, Porsche, BMW, etc., and they all look pretty much to same...

there appears to be no difference between circa 2000 and 2010 technology...nor 1920 deisel technology for that matter...
but as far as commercial DI in cars, the tech is young...
2 things can happen:
first, they consider it a 'non- issue' and do nothing
second, they consider it an 'issue' and try to mitigate it more than they already have
