| Research Abstract |
On the growth of nano-particles in the internal combustion engines starting from the ignition and combustion of fuels, following points were little known; the ignition mechanism of real fuels, and the reaction mechanism of unsaturated species which strongly related to the production of poly aromatic hydrocarbons, the precursor of the nano-particle. The ternary mixture of n-heptane, iso-octane, and toluene is assumed to be a minimum surrogate fuel, which is a model fuel for the combustion simulation of gasoline. The goal of this study is the development of the detailed chemical kinetic model for the oxidation of gasoline surrogate fuels under the engine environment.
The model was constructed based on the literature data and the quantum chemical calculations. The proposed gasoline surrogate fuel model includes low temperature oxidation kinetics, which is important under the engine environment. And, to obtain the measurement data such as ignition delay times for the validation of the model, high-pressure shock tube and constant volume chamber were designed and developed.
