Abstract

Diesel engine emissions are under scrutiny in various fields. Due to its complex air quality and climate relevancies, the parallel measurement of size distribution and the spectral responses of thermally pretreated diesel particulate matter (DPM) provides a powerful opportunity to better understand its environmental impact and serve as a novel method for emission-based fuel development. In this study, we demonstrate the experimental results of number concentration, size distribution, and absorption spectra measurements of DPM as function of the operational conditions of diesel engines using different fuel types by 4-PAS and SMPS. The numberconcentration and the population statistics including TNC, TVC and GMD values as well as the absorption responses including OAC and AAE data at different operational wavelengths were measured at each operational mode of the engine using pure petroleum based B0 and FAME mixed diesel fuels at three different TD temperatures. The thermal evolution of the investigated emission was also investigated at all measurement conditions. The results demonstrate the applicability of multi-wavelength PA spectroscopy for the qualitative investigation of diesel emissions and thermal evolution using a multi wavelength PA instrument - thermodenuder unit combination.
