How is soot formed in engines
WebBasically soot in an internal combustion engine is produced in a very fine, sub micron form. It’s a normal process when distillate fuels are burnt in a compression ignition engine, despite advances in all modern engines, primarily driven by emission regulations. These advances mean that less soot is produced per ignition stroke. WebIn its final form, soot is a solid-like graphite, but it is initially formed from gaseous hydrocarbons. Experimental evidence indicates that it goes from a gas to a liquid before …
