Abstract

Absorption and extinction due to the smoke produced by the atmospheric combustion of diesel fuel have been measured using a CO2 laser spectrophone at a wavelength of 10.6 μm. The absorption coefficient normalized to the aerosol mass density is 0.84 ± 0.076 m2/g, and the total scattering coefficient (the difference between the extinction and absorption values) normalized in the same way is 0.15 ± 0.014 m2/g. The largely fibrous aerosol was found to be 80% carbon, with most of the remainder consisting of hydrocarbons which are comparatively transparent at 10.6 μm and physically resemble the unburned fuel. The normalized coefficients of this study approximate those of diesel automobile effluents. This is not surprising since the aerosol composition and morphology appear to be similar.
