PhD funded by ADEME and PSA.The first part of this research work was devoted to a bibliographic synthesis on the carbonaceous aerosol; an analysis of its composition, structure and physico-chemical behaviour is discussed. This section introduces a second chapter, dedicated to the development and presentation of numerical tools to describe all chemical and microphysical processes involved. The formation of condensable secondary species is particularly discussed, they are produced by photooxidation in the atmosphere (gas / particle transfers). An innovative aerosol modelling approach, considering particle morphology, is proposed. Indeed, the scientific community has described up to now the different processes assuming spherical particles. Although this approach is classic for the formulation of processes, it seemed important to introduce a fractal morphology parameter into the description of these processes. Indeed, we see that the gas / particle exchange surface is of major importance for heterogeneous chemistry processes (absorption, surface catalysis, etc. ). The fractal dimension parameter thus makes it possible to quantify the surface / volume ratio of particles. The importance of mobile sources contribution on the total load of particulate matter in urban areas has driven us to study the evolution of particles emitted by a single vehicle. In actual emission conditions, the fractal particle model tracks the evolution of the particles (compositions, sizes, etc…) from the exhaust pipe to the ambient environment. We observe that combustion particles are particularly well described by the fractal approach. Sensitivity analyses are presented. The impact of the sulphur content of fuels is analysed, which will explain the outbreak of nanoparticles at the exhaust, phenomenon observed by some authors. Due to these adverse effects on catalytic systems, sulphur is involved in future fuel regulations by 2004 in Europe and the United States.
