A Soot Precursor Formation Embedded Reaction Mechanism of Diesel Surrogate Fuel

摘要

A new chemical kinetics model of diesel surrogate fuel including polycyclic aromatic hydrocarbon formation and growth is presented, which consists of 153 species and 697 reactions. Comparisons with various experimental data available in the literature, including shock tube, n-heptane premixed flames, jet stirred reactor and homogeneous charge compression ignition engine, show good performance of this new chemical kinetics model. The presented mechanism can be used as the basis for further reduction and is applied to the combustion and emission simulation by coupling chemical reaction kinetics model with computational fluid dynamics model in internal combustion engines.
