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. WebThe standards for emissions from diesel engines are becoming more stringent and accurate emission modeling is crucial in order to control the engine to meet these standards. …
