 Any chance you can run your generator at 3600 rpm? Technically, I don't know what's involved, but your motor would be a lot happier there & I'll bet it would soot up a lot less.

Rolf, All,

I also appreciate the advantages that a fixed, indoor installation could
provide a alternate fuels engine.  I have not yet tried WVO but have been
experimenting with 2 micron filtered WTF (Waste Transmission Fluid in this
context).  My plant started off with a 1984 1.6NA out of a Jetta.  The
engine had next to no oil pressure and severe blowby so I found a good shape
1980 1.5 NA with which to replace it.  During tests of the 1.6 (it actually
ran pretty well once started),  I saw better output power and smaller
throttle openings for a given load on WTF than on straight diesel.  With the
1.5,  I do not get as much power with the WTF and after an hour or so the
engine cokes up and the RPM drops.  Switching to clear diesel and running it
extra hard with throttle bursts clears it up and then it runs fine.

When I just pulled the injectors from the removed 1.6 engine to try to
liquefy the carbon deposits in the rings lands with solvent soak I noted
that the injector heat shields were coked up so badly with solid carbon that
only the tiny needle from the center of each injector was protruding into
the pre chamber.  That must be what the WTF does to these engines at 1800
RPM.

This was a huge disappointment to me as I was counting on using WTF as a
main fuel for power generation here.  If the problem will clear by diluting
it with a small amount of diesel that would be better than nothing.  Maybe
is is particulates in which it will be rich smaller than 2 microns that are
causing the carbon buildup.  If I have to build a vacuum distillation plant
to process my WTF that would take all the fun out of it.  I have the option
of going to WVO still but would have to modify my fuel handling equipment a
bit, but not if I can get used Canola that stays liquid.  My present system
is the result of a lot oif $$ for components and effort.  It is dual fuel
and has separate tanks and valving for both clear diesel and WTF.  Each tank
has it's own filters (10 and then 2 micron), and in the case of the WTF the
oil is heated to engine coolant temp in a liquid to liquid heat exchanger to
remove water and thin it prior to hitting the filters.   It  probably has
cooled to 130 degrees F when it hits the FI pump inlet.

In the USA the government has a Federal Department, a Bureau that appears to
look after automatic transmission fluid.  I could contact the BATF for
suggestions and ask them WTF regarding  my coking problem?  I suspect though
if I mention coking they will probably refer me to the DEA. The DEA would
not have juristiction to assist me in Canada so they would likely transfer
my request to the RCMP (Research in Canada for Multiple uses of Petroleum).
That would probably not give useful results.  I suspect I am more expert on
this subject now than any government agency.

If members here have any good technical ideas I would appreciate your input.
That BATF stuff was meant as a joke in case anyone isn't sure. ;)
