| Tartalmi kivonat: | This work discuss some results of the extended measurement campaign focussing the in-situ microphysical characterisation of the emitted diesel particulates of different fuel types at diferent operational condition of diesel engine. For measureemnt of the spectral repsonses and the size distribution of the diesel emission customised multi wavelength photoacoustic spectrometer and single commercially single mobility particle sizer were uesd. Basee on the size distribution data we experimentally demonstarte that at idle the emitted aerosol assembly have bimodal distribution in all type of fuel and working point of engine. We also demonstarte that the spectral responses of the diesel aerosol is characterisits for the type of fuel and the operational condition of engine. Using posterior temperature treatement we manifest that especially at idle the volatile fraction of the emitted aerosol can dominantly removed above 150C temeperature. Finally, we also experimentalla demonstarted that the biodiesel content of the diesel fuel even in its relatively small blending even in a relatively small (<7%) mixing ratio can significantly modify the climate and health relevant microphysical feature of the diesel emission. |
