Regarding H2 as an accelarent. for the power stroke of an IC. I have read that some research regarding the detonation of fuel air mixtures, using the addition of metal catalyst's permanently attached to the piston or cylinder walls, This accomplished a high temperature reaction which provides "extra" hydrogen derived from steam. This being a development originating from research carried out on WW 2 fighter aircraft engines, to obtain a power boost during combat operations, including the injection of a water/methanol mix during the required "boost" period. It now seems that we are to have this mixture imposed by Government mandate without the "catalysts" to run our gasoline engines, Perhaps we should all use platinum tipped spark plugs to help with the reaction. All thanks to the corn lobby.

Tom From: [email protected] [mailto:[email protected]] On Behalf Of Thomas Reed Sent: Tuesday, June 28, 2011 6:26 PM To: Discussion of biomass pyrolysis and gasification Cc: Sridhar Gururaja Rao; <[email protected]> Subject: Re: [Gasification] Producer Gas Engine Paper Dear Eric and all You commented on the lack of knock in engines running on producer gas. The Octane of a fuel turns out to be 10x the compression ratio at which the engine will knock on a fuel in that engine. Typical gasoline engines today have a CR of 8.5 and won't knock on 85 octane gasoline, but will knock on 80 octane gasoline. Small planes typically demand high test gasoline 100 octane and have a CR of 10:1. It is important to use the highest CR that a fuel will support. Both power AND efficiency increase linearly with CR. I believe the octane of producer gas is over 150, and I have been urging all to raise the CR of engines running PG. My company, CPC, ran PG in an engine with CR 15 and got no knock and spectacular power and efficiency. It took five years to get them to do it.

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 (Ed.), ISBN: 978-953-307-401-6, InTech, Available from: http://www.intechopen.com/articles/show/title/facts-about-producer-gas-engine 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.
