Outline of Final Research Achievements

The reaction mechanism which contributes to generation/reduction control of the polycyclic aromatic hydrocarbon (PAH) generated in an engine combustion was studied. As a result of examining the ignition combustion characteristic of the composite fuel of saturated hydrocarbon and aromatic hydrocarbon using the rapid compression-expansion reactor which simulated the engine cylinder, it turned out that the character of ignition for the mixed fuels has good correlation with research octane number. Also, it was found that equivalence ratio for oxygen in the air should be suppressed under 3 with generation control of PAH(s) generated from aromatic hydrocarbon in the fuel. Moreover, a reaction model which includes primary reference fuel with toluene and PAH generation was constructed from exiting models for system integration. As a result of chemical kinetic simulation it was also found that it is important to control the equivalence ratio less than three.
