I presume that this would greatly increase power >and efficiency of PG, but I don't know if they could increase CR enough to accommodate PG.<br><br>You can dig out all the facts for yourself, but the success of extracting the maximum energy of the producer gas is not only the engineering nuts and bolts, cams, turbo, intercoolers, compression ratios, rpm, etc, but to the software developed to manage producer gas. These are the new engines we have been waiting for, at least for clean producer gas, but even using that term can open up a can of worms for the engine warranties.<br><br><br>What we don't see spelt out about producer gas, is that it's variations away from what we might call "normal analysis" is infinite, and how that affects the combustion chemistry, engine operation and/or it's componentry life. That we might choose to fiddle with older basic slow speed engines to make them perform better for basic electrical and mechanical power, these modern high speed engines place real challenge on the gas making consistency.<br><br>Gasification remains for me one of the most challenging technologies that have crossed my path, and if I think for one minute I have it by the tail, the other end will bite me given the right conditions.<br><br>Onwards as Tom R. suggests.<br><br>Doug Williams,<br>Fluidyne...<br><br>-------------- next part --------------<br>An HTML attachment was scrubbed...<br>URL: <<a href="http://lists.bioenergylists.org/pipermail/gasification_lists.bioenergylists.org/attachments/20121014/ad1614cf/attachment-0001.html" target="_blank">http://lists.bioenergylists.org/pipermail/gasification_lists.bioenergylists.org/attachments/20121014/ad1614cf/attachment-0001.html</a>><br><br>------------------------------<br><br>Message: 2<br>Date: Sat, 13 Oct 2012 22:50:07 -0500<br>From: "Pete & Sheri" <<a href="mailto:spaco@baldwin-telecom.net">spaco@baldwin-telecom.net</a>><br>To: "'Discussion of biomass pyrolysis and gasification'"<br> <<a href="mailto:gasification@lists.bioenergylists.org">gasification@lists.bioenergylists.org</a>><br>Subject: [Gasification] Lister on Gasoline, ingition control device?<br>Message-ID: <000601cda9bf$00eb4a00$02c1de00$@net><br>Content-Type: text/plain; charset="us-ascii"<br><br>Hello, Ken.<br><br> Did you ever publish the circuit for your ignition control device?

Ron Ohler and Andy Schofield went on to get the engine<br>> running sweetly, after a lot of fiddling looking for the best ignition<br>> point.<br>><br>> I have now returned to the UK, and I am keen to maintain interest<br>> going in the spark conversion of diesel engines. The developing<br>> countries are littered with small hp diesels such as Lister, Petter,<br>> Changfa clones performing pumping, generation and agricultural<br>> processing tasks. To come up with a cost effective spark conversion<br>> for these generic engines so that they can be economically run on<br>> producer gas from biomass, would be a major step towards petroleum<br>> independence.<br>><br>> The original IISc paper describing the performance testing of a 3<br>> cylinder spark converted Indian diesel engine at 17:1 CR is here:<br>><br>> <a href="http://cgpl.iisc.ernet.in/site/Portals/0/Publications/ReferedJournal/Biomass%20derived%20producer%20gas%20as%20a%20reciprocating.pdf" target="_blank">http://cgpl.iisc.ernet.in/site/Portals/0/Publications/ReferedJournal/Biomass%20derived%20producer%20gas%20as%20a%20reciprocating.pdf</a><br>><br>><br>><br>> regards<br>><br>><br>><br>> Ken Boak<br>><br>><br>> _______________________________________________<br>> Gasification mailing list<br>><br>> to Send a Message to the list, use the email address<br>> <a href="mailto:Gasification@bioenergylists.org">Gasification@bioenergylists.org</a><br>><br>> to UNSUBSCRIBE or Change your List Settings use the web page<br>> <a href="http://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenergylists.org" target="_blank">http://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenergylists.org</a><br>><br>> for more Gasifiers, News and Information see our web site:<br>> <a href="http://gasifiers.bioenergylists.org/" target="_blank">http://gasifiers.bioenergylists.org/</a><br><br>-------------- next part --------------<br>An HTML attachment was scrubbed...<br>URL: <<a href="http://lists.bioenergylists.org/pipermail/gasification_lists.bioenergylists.org/attachments/20121014/5c41e00d/attachment-0001.html" target="_blank">http://lists.bioenergylists.org/pipermail/gasification_lists.bioenergylists.org/attachments/20121014/5c41e00d/attachment-0001.html</a>><br><br>------------------------------<br><br>Subject: Digest Footer<br><br>_______________________________________________<br>Gasification mailing list<br><br>to Send a Message to the list, use the email address<br><a href="mailto:Gasification@bioenergylists.org">Gasification@bioenergylists.org</a><br><br>to UNSUBSCRIBE or Change your List Settings use the web page<br><a href="http://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenergylists.org" target="_blank">http://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenergylists.org</a><br><br>for more Gasifiers, News and Information see our web site:<br><a href="http://gasifiers.bioenergylists.org/" target="_blank">http://gasifiers.bioenergylists.org/</a><br><br><br><br>------------------------------<br><br>End of Gasification Digest, Vol 26, Issue 9<br>*******************************************<o:p></o:p></p></div><p class=MsoNormal><o:p> </o:p></p></div></body></html>
