[QUOTE="Rich Rohrich, post: 1232409, member: 16241"] I cut and pasted this from an article (Fuel for Thought) I originally wrote for Dirt Rider magazine in 1985 and rewrote in 1999 for Eric Gorr's website. It's the most referenced fuel article on the internet over the last 5 years. I'm not some clown incorrectly parroting some BS I read somewhere. If you are going to act condescending out here, you really might want to pick your spots a little better. ;) As the original poster describes the situation, the [b]basics[/b] that you are so intent are hammering out are fairly simple. The conditions for spark knock (or ping if you like) are not normally present in a closed throttle situation. Without hearing it I can't say for sure what it is, but I can tell what it ISN'T. ;) For anyone who is interested in more specifics on knock and some combustion basics in general here is some additional info. Original fuel article referenced above [url]http://www.polariswatercraft.com.au/fuelforthought.htm[/url] Additional References I have found very useful. Harold H. Schobert - The Chemistry of Hydrocarbon Fuels - Butterworth-Heinemann Ltd. Keith Owen, Trevor Coley - Automotive Fuels Reference Book - SAE - R151 H.P. Lenz - Mixture Formation in Spark-Ignition Engines - Springer-Verlag Germane, Wood, Hess - Lean Combustion in Spark-Ignited Internal Combustion Engines - A Review - SAE paper 831694 Z.
