ECO is abbreviation for eco-diesel, the name given by VW to the 1.6 TD
with the fueling cranked down to burn as cleanly as possible.  I think
what Hagar is doing is the eco-diesel approach.

The TDIs are 1.9's and up.  All the 1.6D's have swirl chambers AFAIK.


p.s. I had to jump in on this thread to get a chance to say thanks for
the generator links, interesting stuff.
