I ask, “What makes burning diesel fuel so polluting ?” And, “Are there any ways to prevent this ?”
And so I enter a whole new world of acronyms, three-letter and otherwise.
Vapour, vaporised, and vapour-borne molecules and elemental atoms and ions make their way out of the diesel vehicle exhaust, subject to three key processes : condensation, nucleation and agglomeration (or accumulation).
Those particles that were solid post-combustion form potential nucleation and condensation surfaces.
Of the rest, whether they stay vaporised depends on their boiling points.
