Excerpt from The Engineering Digest, Vol. 3: January-June 1908Results of experiments made by Dr. K. 0. Fall: explain the apparent inconsistency be tween percentage of hydrogen in the gas and the conditions of preignition. It appears from his ngures given for the temperature of igni tion that in a producer gas containing hydro gen and CO with various neutrals mixed with oxygen the temperature oi ignition does not depend on either the hydrogen necessarily nor the CO necessarily in the mixture. But on the relation that one of these bears to the oxygen present and which one can be determined only by computing the temperatures of ignition tor the value and taking that value which is lower. One very significant fact in addition to the above is brought out by these results. And that is that the ignition temperatures and compressions formed are all very much higher than these used in engines. No ordinary en gine uses compression anywhere near those determined for preignition.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
