Abstract:
A set of associated information models purposed to investigate and optimize coupled physical and chemical processes in the piston combustion engine is developed. It differs from prototypes by enhanced physical consistence, by improved chemical resolution, by the module-oriented structure and respective computer-aided tools, as well as by the higher constants reliability. In addition the following results are of a great separate importance: an original technique of the approximate solution of the flame equation, a two-scale averaging procedure applicably to the kinetics?diffusion problem and finally a factorization approach to computing of the minor toxic constituents in the charge. Designed models enable in practice to simulate multiple fine features of the engine dynamics including non-stationary regimes and alternative fuels. Furthermore the elaboration may be easily applied to other energy transfer combustion systems.
