| Abstract: | Three-dimensional numerical simulation in cylinder combustion was carried out based on a single cylinder direct inject diesel engine,while the detail chemical reaction mechanism of n-tetradecane was considered,and the enthalpy calculate subroutine of chemical species was built.The formation and evolution mechanisms of aromatic(benzene) and polycyclic aromatic hydrocarbon,which were the precursor of soot particle,were calculated.Soot particle mass in cylinder combustion was calculated by Belardini soot model... |
