Diesel exhaust DE gas is a major contributor to combustion -derived particulate-matter air pollution. However, empirical models cannot be used to investigate the underlying mechanisms of soot production. Detailed theoretical soot models contain all the components present in the soot formation with a high level of detailed chemical and physical processes. However, further advancement of comprehensive theoretical models must be preceded by the more detailed and accurate formation mechanisms. On the other hand, empirical and semi-empirical models ignore some of the details in order to make complex model simple and to reduce the computational cost and time. From Wikipedia, the free encyclopedia. Aliphatics appear to first form acetylene and polyacetylenes, which is a slow process; aromatics can form soot both by this route and also by a more direct pathway involving ring condensation or polymerization reactions building on the existing aromatic structure.
