Great post Mr Tone, Finnaly someone who understands at a working level that IC engines are gasses expansion engines. The heat in-cylinder made is to make the in-cylinder gases expansion. The fuel in-cylinder is to make the in-cylinder heat to make the all gases present expansion. And you actually only need the amount of oxygen molecules present to fully combust the in-cylinder used fuel blends. High carbons fuels need more oxygen molecules than low-carbon, high hydrogen fuels. The heat made is the same. Rate of heat energy made/released, and therefore expansion, does vary. From too slow, unable to harness/convert. To much too fast and pressure spiking destructive. Ha! Ha! I really needed you here on the DOW, man 9 years ago: > [@The NEED and Effects of Expansion Gases within an IC Engine Cylinder](https://forum.driveonwood.com/t/the-need-and-effects-of-expansion-gases-within-an-ic-engine-cylinder/1219): > > Hi All A new “good” gases topic to chew on. Since the DOW is dedicated to “Drive On Wood” and “Power On Wood” then woodgasification is all about making useable shaft power with the woodgas. From a today practical stand point then you are going to be making this shaft power with one of the today far over existing in-place 10,000,000,000 (10 BILLION +) piston internal combustion engines already on the face of the planet. NO need for a new woo-woo engine at all. Expansion gases to push that pi… You write much more compactly than me.
