Abstract

Diesel combustion has been studied under simplified experimental conditions by means of 2D-laser light scattering techniques and chemical analysis of gaseous and condensable material sampled by a fast-acting valve. Two model fuels consisting of a simple alkane hydrocarbon and an aromatic/aliphatic mixture have been used in order to verify the effect of the fuel specificity on the combustion process. For both fuels the combustion proceeds through the formation of CO and subsequent oxidation to CO(2), which is anticipated with respect to the appearance of a scattering signal due to soot formation. It is shown that this is the only pathway through which soot oxidation takes place in characteristic time scales comparable to those of its formation.
