TD4 running rough low rpm / pinking knock

Skinny Mike said:

If mine makes a rattle or pinking sound I do this.
On fill up, 500ml of mineral 2 stroke, double shot of Miller's ecomax, and good quality diesel, I use Texaco religiously.
Be warned, you'll only get 300 miles to the tank of fuel!

Then use 200ml of 2 stroke on every fill up. Miller's is a personal choice.

I normally only have to do the big treatment once a year. Usually after winter. Other than that, for an old diesel, it's quiet and smooth running.

that rattle or pinking sound be just a mild version of diesel clatter / knock
mostly heard from pre-common rail types

to reduce that 'clatter' in c.m. types .. combustion chambers were redesigned
and 'injection' be determined by the engine management computer

a poor spray pattern from the injector nozzle ..
or a miss timed injector pulse ..
would increase the potential for more 'clatter' ..

the td4 .. and other c.m diesels ..
use a couple of injection pulses per cycle ..
if one is slightly miss timed .. maybe due to residue inside the fuel passages
then there's another setup to produce that tinkling > clatter noise

see paragraph starting " The fifth requirement of a modern diesel is pilot injection. "

( g.search : https://www.google.co.uk/?gws_rd=ssl#q=Diesel+Knock-The+quiet+diesel+evolution )

add the potential to fill up with crap fuel ..
one that don't combust as it should ..
more potential for diesel knock
