| Abstract: | Three methods for measuring the soluble organic fraction of diesel engine exhaust particulates i.g. thermogravimetry, Soxhlet extration and vaccum volatilization are comparatively evaluated. (It appears that vaccum volatiliation method is simple in operation, possible to process dozens of samples simultaneously and the sampling filters both with and without teflon coat are compatible with this method). Comparative tests show that total volatile fraction in sampled particulates measured by vaccum volatilization is equal to the soluble organic fraction measured by Soxhlet extraction. Soluble organic fraction and dry soot emissions from 6110 type diesel engine under different operating conditions are measured by vaccum volatilization and presented in the paper. |
