Outline of Final Research Achievements

The relation between Livengood-Wu integral and knock was clarified and the unresolved problem of the cetane number and autoignition properties of homogeneous premixture was resolved by using the adiabatic mixing model and zero-dimensional calculations. It was shown that the detailed kinetic mechanism can be used to predict the in-cylinder laminar burning velocities at high pressure and high temperatures, and the effect of the EGR on the burning velocities has been estimated. The new PAH formation route via fulvenallenyl radicals has been investigate by quantum chemical calculations.
