Dear Erin,
In the late 70's United Technologies tested engines on produced
gas from a molten metal gasifier (pyrolyzer using molten lead) and
found the same conclusion, the effect is that the CO reduces the flame
propagation rate and ignition temperature to prevent knock at higher
compression ratios. This means a lot for deratings on IC engines on
produced gas. Even considering this was not nitrogen diluted gas, the
results were very encouraging in their publication. They made
interesting arguments on how to keep the lead from proceeding through
the system into the ash, but the work was not continued.
It was quite humorous to see many years later Molten Metals
attempted to convince the world that this would work and used up a lot
of Gore's DOE earmarked (or other not so polite manner of securing
them) funds to leave a plant which is now on the sale block for a
fraction of it's original value. The Navy told me that it would never
be put on ships, resisting significant pressure to do so.
Sincerely,

Subject: [Gasification] Producer Gas Engine Paper
Sridhar recently forwarded us information about his paper about
Producer Gas Engines. It is an interesting paper, and we've posted a
link to it from the gasification web site, but you can also get it
directly from the publisher with this link.
G. Sridhar and Ravindra Babu Yarasu (2010). Facts about Producer Gas
Engine , Paths to Sustainable Energy, Jatin Nathwani and Artie Ng

To sum up, they connected an engine that has been designed to run on
producer gas, to a downdraft gasifier, and recording and analyzing the
results. There may be some surprises here, like the lack of knock at
higher compression ratios, and the information gathering is both sound,
and beautifully presented. Cheers,
