[Vwdiesel] Diesel Fuel part 14 ---- ( Mixture talk )

[H . Hagar.]

See  Fuel  101  as well.

Can the word mixture be used talking about diesels ?   ABSOLUTELY.

I am writing about old Rabbits only.      Some gassers need extra fuel  RICH   or they
self destroy in short order. ---NOT so with a diesel  in can be run as lean as you can make
it ---and like it.     BUT     too much fuel ?  may destroy it.

In this forum we have two extremes    Jake  and Hagar.      Jake super rich and
Hagar super lean. ---- Hagar 78 Miles to a gallon imp   ---ask Jake what he gets.

        100----------------50-----lean----------0--------------50-----rich--------------100.

So when you buy a new Rabbit   what is it set for   mixwise.?.    It will jo jo from full fuel to
little fuel according to how you dance on the pedal. --------rich lean rich lean  and so on.

The intake is designed for delivering AIR for full power  ---and with no restrictor like a butterfly
the mix at no load will be  LEAN side of 0.  control collar bares the two drainholes
on high pressure piston. When you step on it  --the governor and a mess of springs and levers
will move the   control collar right to the mechanical stop --we call fueling screw. Or
if you like maximum fuel stop.   If you turn the screw all the way in ?   ---the drainholes will
be mostly covered.   Turn it max out   --about  4 turns then the holes will not be covered as much
the stop is solid. LEAN and mean like BUNNY BONDO.

Jake got his wide open  ---running way on the rich side of  0 .

As you can see there are many shades of LEAN   and many shades of RICH.

Mixture is defined in USA   as so many pounds of fuel and so many pounds of air.

The flyboys got a mess of experience in this field.   It was one of my dreams to
Install Mixture control and meters  ---simple to do if you have an LDA   ---

Do some VW come with automatic mixture control ?   yes indeed   --
it is called an ADA.---looks like the LDA.

So if you like to turn the fueling screw OUT ?   no probleme.   Worried about loosing
the setting ?   NO problemo . Turn screw all the way in. then out 3 o4 4 turns.--
Then a bit of Tuning .Remember you must jockey idle and fueling. Back and forth.

Hagar.

PS :    Yes   Bunny Bondo is a leftie.  By the way the control collar go to
full power  the minute you tell the governor (pedal) you need more poop.
