Let's stop on consideration of the question connected to a substantiation and development of mathematical model of processes mixing and combustion in the cylinder of a diesel engine liquid alternative fuels (АF). In our opinion, in view of difference of physical and chemical properties АF, it is possible to apply to alternative fuels the developed mathematical model of mixing processes and combustions liquid hydrocarbonic fuels an oil origin which substantive provisions are stated above.

       To the physical properties of fuel influencing dynamics of a fuel jet and atomiaztion with other things being equal, viscosity, a superficial tension and density concern. At increase of viscosity grows distance a fuel jet that reduces a share volumetric mixing and results in hit on walls of the chamber of combustion of a lot of fuel. With downturn of viscosity of fuel average diameter of drops of fuel decreases and becomes more homogeneous atomize. However thus the corner of dispersion of a fuel jet increases, and distance decreases. The the superficial tension is higher, the drop is especially steady against influence of external forces and the more than its sizes. The less superficial tension, the is more thin and is more homogeneous atomization some fuel that promotes acceleration of mixing processes and combustions.
