Fiddlin' with the fuel injector thing on a 200tdi

o and eeyore, go back bed :lol: :lol: :lol:
or come of the pop :lol: :lol:
thats setting the timing up and fine tuning the timing, were onabout tweaking the fueling of the engine here :lol:

oooo meant in the nicest possable way btw if you take it the other way :lol: :wink:

--- Quote from: "Eeyore" ---Close description as to what happens but not quite. :wink:
Without disassembly, all you're doing is altering the fuel pump timing, not the actual quantity of fuel entering the cylinder. Too late with the timing and you're pushing cold combusted fuel into the exhaust and making lots o' smoke and loosing power. Too early and your retarding the motion of the piston and risking diesel knock (which leads to a very hasty failure of the piston).
There is a tolerance on the timing set at Solihull and this is why adjusting the pump has more effect on some engines than others. Just moving the timing a set amount will give a very variable result dependent on how the timing was originally set. :wink: If that makes any sense!

I also disagree...
When you move the diaphragm - you are not adjusting fuel injection timing, but adjusting the amount of fuel compensation vs. boost.
Unless I'm missing the obvious.
The only way the injection timing would change is by loosening the three bolts on the fuel pulley drive and moving it.
I also agree with the adjusting things comment... if you don't know what your doing, then don't (usually).

dont worry, i warned him :wink:
dont forget there some of us running with stupidly tweaked tdi's on here , aslong as your sensible and not stupid you have no problems, o unless your names mike :twisted:
