Abstract

The formation of soot particles is one of the most complex problems in combustion science, still by for not well understood. However, intense experimental and theoretical researches within the last two decades improved the fundamental understanding and led to detailed picture of the soot particles formation process. This paper discusses soot combustion fundamental processes in term of the in-cylinder combustion and emission. The new research requested both simulation and experimental researches to study fundamental process involved in diesel engines in order to define possible strategic scenario toward zero emission level. Our investigations can be divided into groups, which are however closely linked with each other: 1. The application of chemical kinetics to problems relating to the theory of combustion and explosion processes. 2. Mathematical formulation of the concentration of reactants. 3. Experimental and simulation results of soot in-cylinder concentration. 4. The influence of antismoking additives on thermal and combustion efficiencies. This paper presents data from tests conducted by internal combustion diesel engines, a testing laboratory and results of numerical simulation. The results of calculation are compared to experimental data showing good agreement for soot particles concentration in diesel cylinder.
