Abstract

It is important to know the behavior of fuel air mixture in a molecular level, when aiming at improvement in fuel consumption of a gasoline direct injection engine, and reduction of a particulate matter. However, the research from the viewpoint of the theory of gas dynamics has not progressed in this field. In present research, as the representative of hydrocarbon fuel, the fuel air mixture of isooctane of the octane number 100 or n-heptane of the octane number 0 is treated. The molecular dynamics simulation and analyses are performed, in order to clarify the change of molecular structure distribution of the hydrocarbon molecules and the change of their movement with temperature and density.
